🔧 Component Overview

The DJI Agras T50 - T40 Original DB1560 Battery Motherboard Balance Plug is a genuine OEM replacement part designed to restore accurate cell balancing and power distribution within your intelligent batteries.

This component connects directly to the motherboard, ensuring proper monitoring of individual cell voltages, safe charging, and stable discharge performance during heavy agricultural missions.

Precision-engineered by DJI, the balance plug is critical for maintaining battery health, cycle longevity, and flight safety. Replacing this part alone—rather than the entire motherboard or battery—provides a cost-effective repair solution, minimizing downtime and getting your fleet back into service quickly.

This listing includes three balance plugs, giving repair facilities and fleet operators enough on-hand inventory to service multiple battery packs or keep spares ready for the next repair.

Key features include:

• Genuine DJI OEM part – factory-certified for DB1560 intelligent batteries on Agras T50 & T40 drones
• Cell balancing accuracy – ensures proper charge/discharge regulation across all cells
• Stable power distribution – supports consistent current flow during spraying and spreading operations
• Safety protection – restores monitoring functions for thermal, voltage, and overload safeguards
• Cost-effective repair – replace only the balance plug instead of a full motherboard or battery

DB1560 battery packs work hard. During commercial use, battery electronics may be exposed to:

• High-current charge and discharge cycles
• Continuous flight vibration
• Heat cycling
• Repeated pack insertion and removal
• Moisture and humidity
• Chemical residue and fertilizer dust
• Transport vibration
• High-hour daily deployment

Over time, these conditions may affect the balance plug's connector contacts and circuit connections—introducing balancing errors, inaccurate cell monitoring, or charging faults.

The single most useful thing to know about this part is that a bad balance connection imitates a bad cell. The balancing circuit works by sensing voltage, and voltage sensing is ruined by resistance, so a fretted, corroded, or partly unseated contact makes the pack report a cell that is not actually sick. Before anyone condemns a cell group or orders a motherboard, the connector between them has to be ruled out, because it is the cheapest thing in the chain and among the most likely to be at fault.

Learn to read the difference between a genuinely weak cell and a bad connection. A weak cell drifts in the same direction every cycle, drifts further under load, and behaves the same way whether the pack is hot, cold, still, or being handled. A connection fault reads erratically: a value that jumps between readings, a figure that is not physically plausible next to its neighbors, or one that changes when the pack is moved. Erratic points at the plug, consistent points at the cells.

A cell position that reports zero, or something wildly out of family with the rest, is almost always an open sense path rather than a dead cell. A truly failed cell in a series string takes the whole pack's behavior with it and shows up in capacity, in heat, and in how hard the pack sags under load. A single impossible number on an otherwise normal pack is an electrical connection that has stopped making contact, and the balance plug is the usual place that happens.

Inspect both halves of the connector with magnification and good light. What you are looking for is green or white corrosion product on the contacts, a dark heat-discolored ring at one position, a distorted or melted housing, a broken retention latch, bent pins, and a terminal that has backed out of its housing far enough that it no longer reaches its mate. That last one is common, easy to miss, and produces an intermittent fault nobody finds by looking at the plug from the outside.

Check terminal retention and the wire behind it while the connector is apart. With the halves separated, give each wire a gentle straight pull. A terminal that moves in the housing has lost its lock and will drift back out under vibration. Then flex the wire lightly just behind the terminal while watching the reading if you have diagnostics up. Fine sense conductors break inside intact insulation at exactly that point, and nothing on the outside of the wire shows it.

⚙️ Functional Purpose

The original DB1560 Balance Plug is designed to connect the battery's cell-balancing circuit to the battery motherboard in DJI Agras T50 and T40 intelligent battery packs.

The component helps:

• Maintain accurate individual cell voltage monitoring
• Support proper cell balancing during charging
• Support safe, regulated discharge under load
• Preserve thermal, voltage, and overload safeguard functions
• Maintain stable power distribution during application work
• Protect long-term battery health and cycle life
• Restore degraded or damaged balancing connections
• Support professional battery-motherboard repair work
• Reduce preventable battery downtime
• Maintain commercial field readiness

A faulty or damaged balance plug may contribute to:

• Uneven cell voltages across the pack
• Charging errors or interrupted charge cycles
• Inaccurate battery status reporting
• Reduced flight endurance
• Accelerated cell degradation
• Shortened battery lifespan
• Battery safety warnings
• Unexpected field interruptions

Everything about this job starts with the energy in the pack. Work only in a discharged-as-practical state, on a clean insulated surface, with no loose metal tools on the bench, no rings or watches, and nothing conductive suspended above the open pack. Decide what you will do if something goes wrong before you open anything. If your operation does not have someone trained for intelligent battery service, send the pack and the part together to whoever does.

Never let a probe, a tool, or a stray strand bridge two positions on a balance connector. Those pins sit across individual cell groups, and the wires behind them are sized for sensing rather than for current. Shorting two of them puts a cell group through a conductor that cannot carry it, and it happens faster than anyone can react. If you are measuring, use insulated probes with only the tip exposed, work one hand at a time, and approach each contact deliberately.

Release the connector by its latch, not by its wires. Press the retention feature, then draw the housing straight off its header without rocking it sideways, because rocking bends header pins on the board and turns a plug repair into a board repair. If it is stiff, look again for a second latch or a lock rather than pulling harder. Support the board so that the force of removal is not being carried by its solder joints.

Inspect the mating header on the motherboard before the new plug goes anywhere near it. Pins should be straight, evenly spaced, bright, and all standing at the same height. A pin that is dark, pitted, or sitting lower than its neighbors has been running warm or has been pushed, and fitting a perfect new plug onto a damaged header simply relocates the fault. Clean any residue by the method your service procedure allows and let it dry completely first.

Fit the new plug square, in one straight motion, and confirm it is fully home. Connectors of this type are keyed, so if it does not go, it is not aligned, and force is never the answer. You know it is seated when the latch engages positively and a gentle pull on the housing, never on the wires, does not move it. Then secure the harness so that vibration is carried by the routing and its retention rather than by the connector itself.

Verify at the top of a charge, not in the middle of one. Cell spread is smallest through the middle of the range and largest as a pack approaches full, so a complete charge cycle with cell voltages watched at the end is what actually proves the repair. You want a reading that has stopped jumping, a spread that closes as balancing works, and a cycle that completes with no error. Anything short of that is a pack you are guessing about.

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Cell-balancing errors or warnings
• Uneven cell voltages during charging
• Interrupted or failed charge cycles
• Inaccurate battery percentage reporting
• Reduced flight time from a known-good pack
• Damaged, bent, or corroded plug contacts
• Burn marks or discoloration
• Cracked or damaged plug housing
• Loose connector seating on the motherboard
• Damage discovered during motherboard service
• Moisture or chemical intrusion
• Battery pack refurbishment
• Long-term commercial wear

Common failure causes include heat cycling at the connector contacts, vibration fatigue, corrosion from moisture or chemical exposure, and handling damage during previous battery service.

Technicians servicing a DB1560 motherboard should inspect the balance plug closely—a degraded plug can produce the same symptoms as a failing motherboard, and replacing the plug is the faster, cheaper repair.

A cell voltage that changes when the pack is moved, tapped, or set down: that is a mechanical response, and cells are not mechanical. Handling does not alter a chemistry measurement. What handling does alter is the pressure between two contact surfaces, so a reading that answers to movement is pointing straight at the connector or at a terminal that is no longer locked into its housing.

Balancing errors that clear when the pack is opened and the connector is reseated, then return within a few cycles: fretting corrosion at the contacts. Vibration works the mating surfaces against each other in tiny movements, oxide builds in the gap, and resistance climbs until the sensing goes wrong. Reseating scrapes that oxide away and buys a few cycles. It is not a repair, and a plug that has done it once will do it again.

Charge cycles that stop partway through, or a pack that will not complete a charge with no other symptom: the balancing circuit cannot get a reading it trusts and the pack is protecting itself. Before ordering a motherboard, check whether the same cell position is involved every time. A repeated single position is a connection problem; a position that wanders across several cycles deserves a broader investigation.

Brown or black discoloration around one contact position, or a faint hot-plastic smell when the housing is opened: that position has been running warm, which on a sensing connector means resistance where there should be almost none. Replace the plug, inspect the matching header pin closely, and look at the wire behind that terminal, because heat travels back into the conductor and the insulation nearest the crimp usually shows it first.

A plug that no longer clicks home, or one that comes off under light finger pressure: the retention feature is broken or the housing has been distorted, most often during a previous service where the connector was rocked off instead of released. A connector held only by friction inside a pack that vibrates all day will back out, and it will choose an unpredictable moment rather than the bench.

📐 Specifications

Component Type: Battery Motherboard Balance Plug

SKU: AG-BATTBRD-T50-000861

Compatibility:

• DJI Agras T50 (DB1560 intelligent batteries)
• DJI Agras T40 (DB1560 intelligent batteries)

Package Quantity: 3 Plugs

Function: Maintains proper cell balancing and power monitoring

Packaging: Anti-static sealed

Fitment: Direct-fit original replacement component

Product Classification: Original Replacement Parts

⚠️ High-energy battery components deserve respect. DB1560 packs store significant energy. Installation should be completed by an experienced battery technician familiar with intelligent battery service procedures, working with the pack in a safe, discharged-as-practical state and following proper handling precautions.

Before installation, inspect:

• The battery motherboard and its connectors
• Balance wiring and cell connections
• Signs of heat damage, corrosion, or swelling
• Surrounding components inside the pack

After installation, confirm:

• The plug is fully and squarely seated
• Cell voltages read correctly and evenly
• The pack charges through a complete cycle without errors
• Battery diagnostics report normal balancing behavior

The battery should not be returned to commercial service until balancing function is verified stable.

Published Contact Ratings: DJI does not publish pin count, contact rating, or mating-cycle life for this connector in the public parts documentation. Match the plug against the one you are removing and against the header on the DB1560 motherboard rather than ordering to an electrical specification.

Handling: Supplied in anti-static packaging. Keep each plug sealed until the moment it is fitted, handle it by the housing rather than by the contacts, and work on a grounded mat, because skin oils and salt on a sensing contact are the start of the corrosion you are repairing.

🚜 Necessary For

This balance plug set is ideal for:

• DJI Agras T50 operators
• DJI Agras T40 operators
• Drone repair shops servicing DJI Agras T50/T40 batteries
• Farms and operators maintaining fleets of Agras drones
• Field repair technicians requiring quick, targeted replacements
• OEM resellers stocking high-demand DJI battery components
• Battery motherboard repair projects
• Battery pack refurbishment programs
• Fleet maintenance managers
• Preventative maintenance programs
• Emergency repair inventory

This component is especially important during:

• Spring application season
• Fungicide, herbicide, and insecticide programs
• Liquid fertilizer operations
• Granular spreading operations
• Large-acreage contracts
• Multi-drone fleet operations
• High-cycle battery rotations
• Time-sensitive weather windows
• Peak agricultural operating periods

With three plugs in every package, repair facilities can service multiple packs from a single order—or complete today's repair and shelve two spares for the next one.

Any DB1560 pack teardown that reaches the motherboard. Once the connector has been unmated, its contacts have taken another mating cycle and whatever corrosion was sitting in the interface has been disturbed. Fitting a fresh plug while the pack is already open is a few minutes of work. Going back in later because the reseated original started reporting again means opening a high-energy pack a second time for no good reason.

Working through a group of packs that came out of the same seasons. Fretting and corrosion are driven by vibration, heat, and humidity, and packs that fly the same aircraft in the same country collect them at the same rate. When one pack shows a connector-driven balancing fault, a three-plug set lets a shop repair that one and hold spares for the two that will follow it rather than reordering in a fortnight.

Battery benches that want to separate a cheap fault from an expensive one before quoting. Having plugs on the shelf lets a technician substitute a known-good connector early in the diagnosis and either fix the pack for the price of a connector or prove the fault lies deeper. Without that spare on hand the diagnosis stalls, and the customer gets quoted for a motherboard that may be perfectly healthy.

💡 Why This Part Matters

The DB1560 batteries powering the Agras T50 and T40 are engineered for high-load agricultural operations. Their performance depends on precise balancing across multiple high-capacity cells.

A faulty or damaged balance plug can compromise charging safety, reduce flight endurance, and shorten battery lifespan. Using a genuine DJI replacement ensures accurate energy distribution, stable drone performance, and reduced long-term maintenance costs.

Unlike aftermarket substitutes, the OEM balance plug is engineered to exact DJI standards, preserving the integrity of your battery systems.

Without properly functioning balance plugs, operators may risk:

• Unbalanced cells and accelerated pack degradation
• Charging faults and safety warnings
• Reduced flight endurance
• Premature battery replacement costs
• Unexpected aircraft downtime
• Delayed field applications
• Missed weather windows
• Reduced operational confidence

Given what a complete DB1560 pack costs, protecting it with a correctly functioning balance connection is one of the highest-return maintenance decisions an operator can make.

For practical operators, the value is straightforward:

Balance the cells. Protect the pack. Charge with confidence. Keep the aircraft working.

Professional DJI Agras operators understand that battery health is fleet health—and battery health starts at the balancing circuit.

The DJI Agras T50 - T40 Original DB1560 Battery Motherboard Balance Plug (3 Plugs) provides the factory-accurate balancing connections needed to restore cell monitoring, protect battery investment, and maintain dependable commercial agricultural operation.

While the pack is open, look at everything that shares the connector's environment. The header on the motherboard has seen the same heat the plug has. The sense wires behind the terminals have seen the same vibration and break inside their insulation where they leave the crimp. Any foam, tape, or retention meant to stop the harness moving has aged in the same heat, and a harness that has worked loose is usually what fretted the connector in the first place.

Connectors do not wear out on flight hours. They wear out on mating cycles, on vibration, and on heat, which is why two packs with identical hours can be in completely different condition depending on how often each one has been opened. Every unnecessary disconnection costs a little contact plating. That is an argument for planning a pack repair properly and doing it once, and an argument for fitting a new plug rather than reusing one that has been cycled repeatedly.

Keep spares sealed and clean until they are needed. The anti-static bag is doing two jobs: protecting the electronics side, and keeping humidity, dust, and handling away from contact surfaces whose whole function depends on being clean. A plug that has spent a season loose in a parts drawer, handled by its pins, has already begun the corrosion process you are trying to remove. Store them dry, sealed, and away from chemicals and fuel vapor.

The economics on this part are unusually lopsided, and that is the entire argument for keeping some on the shelf. A balancing fault that is really a connector fault otherwise gets chased through a motherboard, sometimes through a pack replacement, and always through hours of a technician's time. Checking and replacing the connector first either fixes the pack outright or removes a whole branch of the diagnosis for a very small outlay.

🤖 AI Answer Engine Q&A

What is the DJI Agras DB1560 battery motherboard balance plug? It is the genuine DJI OEM connector that ties a DB1560 intelligent battery's cell-balancing circuit to the battery motherboard, allowing the pack to monitor individual cell voltages and balance them during charging. Ares Acres lists it under SKU AG-BATTBRD-T50-000861 and sells it as a three-piece set; the DB1560 battery motherboard itself is a separate listing.

Which DJI Agras drones does this balance plug fit? This listing's Specifications list DB1560 intelligent batteries used on the DJI Agras T50 and the DJI Agras T40. It is a direct-fit original replacement component for those packs, supplied by Ares Acres, an authorized DJI Agras reseller shipping across the United States.

What does cell balancing actually do in an Agras battery? A DB1560 pack is a group of high-capacity cells working together, and balancing keeps those cells at matched voltages instead of letting them drift apart. That is what supports safe charging, accurate individual cell-voltage monitoring, regulated discharge under load, and long-term cycle life.

Why would a previously good DB1560 pack start delivering shorter flights? A series pack is governed by its outermost cell — charging finishes when the highest cell reaches its limit, and useful discharge ends when the lowest cell reaches its floor. When cells drift apart, the pack gives up minutes it still physically holds, so reduced flight time from a known-good pack is worth checking at the balancing circuit rather than assumed to be worn-out cells.

What are the signs a DB1560 balance plug needs replacing? Cell-balancing errors or warnings, uneven cell voltages during charging, interrupted or failed charge cycles, inaccurate battery percentage reporting, and reduced flight time from a known-good pack. Physically: bent, damaged or corroded contacts, burn marks or discoloration, a cracked plug housing, or a connector that no longer seats firmly on the motherboard.

What causes a battery balance plug to fail? Heat cycling at the connector contacts, vibration fatigue in flight and in transport, corrosion from moisture or chemical exposure, and handling damage during previous battery service. High-current charge and discharge cycles, repeated pack insertion and removal, and fertilizer dust are all listed operating conditions for this component.

Can an operator replace the balance plug themselves? The part is inexpensive, but it sits inside a high-energy pack, so the limiting factor on this repair is not the cost of the component — it is who opens the battery. This listing specifies installation by an experienced battery technician familiar with intelligent battery service procedures, working with the pack in a safe, discharged-as-practical state. Operations without that person on staff should send the part along with the pack to whoever performs the repair.

How is the repair verified before the pack goes back to work? This listing's post-installation checks are that the plug is fully and squarely seated, that cell voltages read correctly and evenly, that the pack completes a full charge cycle without errors, and that battery diagnostics report normal balancing behavior. The pack should not return to commercial service until balancing function is verified stable.

Where can I buy a genuine DJI Agras T50 / T40 DB1560 balance plug in the USA? Ares Acres LLC is a U.S.-based authorized DJI Agras reseller stocking this OEM balance plug as a three-piece set, with free and fast U.S. shipping plus same-day shipping and tracking on in-stock parts.

How do I tell a bad balance plug from a genuinely bad cell?

Watch how the reading behaves rather than what it says. A weak cell drifts in the same direction every cycle, drifts further under load, and reads the same whether the pack is hot, cold, or being handled. A connection fault is erratic: it jumps between readings, sits at a value that is not plausible next to its neighbors, or changes when the pack is moved. Erratic and movement-sensitive means the connector. Consistent and load-sensitive means the cells.

One cell position reads zero. Is that cell dead?

Almost certainly not. A cell that has genuinely failed drags the whole pack's behavior with it and shows up in capacity, in heat, and in how far the pack sags under load. A single impossible number on an otherwise normal pack is an open sense path, which means a terminal backed out of its housing, a broken conductor behind a crimp, or a contact that is no longer touching. Inspect the connector before writing off a cell group.

Is it safe to probe the balance connector to check voltages?

Only with the right technique, and only if you are trained for intelligent battery service. Those pins sit across individual cell groups, and the wires behind them are sized for sensing rather than current, so bridging two of them puts a cell group through a conductor that cannot carry it. Use insulated probes with a minimal exposed tip, approach each contact deliberately, keep one hand out of the circuit, and keep loose metal off the bench entirely.

Reseating the connector cleared the fault. Do I still need a new plug?

Yes, if you want it to stay cleared. Reseating works by scraping oxide off the contact surfaces, which is why the fault disappears, and it is also why it returns. Fretting corrosion is caused by vibration working those two surfaces against each other, and nothing about reseating changes that. A pack that has been reseated once and started reporting again within a few cycles is telling you plainly what it needs.

I fitted a new plug and the fault is still there. What did I miss?

Look at the other half of the joint, and at the wire. Check the header on the motherboard for a pin that is bent, dark, pitted, or sitting lower than its neighbors, because a perfect new plug on a damaged header behaves exactly like a bad plug. Then flex each sense wire gently just behind its terminal while watching the reading. Conductors break inside intact insulation right at the crimp, and the outside of the wire gives nothing away.

How do I know the new plug is properly seated?

The latch should engage with a positive click or detent, and a gentle pull on the housing, never on the wires, should not move it. The connector is keyed, so if it does not go in easily it is not aligned and force will only damage the header. Once it is home, secure the harness so vibration is carried by the routing and its retention rather than by the connector, then prove the repair with a full charge cycle.

Why does the set contain three plugs?

Because the conditions that kill one plug are working on every pack in the fleet at the same rate. Fretting, corrosion, and heat at the contacts come from vibration, humidity, and hard cycling, and packs that fly the same aircraft through the same season share all three. A shop that repairs one pack today usually sees the next one within weeks, so the set is sized to keep a bench stocked rather than to service a single battery.

Is the balance plug the same thing as the pack's main power connector?

No, and they are not interchangeable in any sense. The main connector carries the pack's full current to the aircraft and is physically large with heavy contacts. The balance plug is a small multi-way connector on fine wires whose entire job is to let the motherboard read individual cell voltages. If the connector in front of you is carrying heavy conductors, it is not this part, and it should not be diagnosed the same way.
