🇺🇸 U.S.A. FIRST

Ares Acres LLC is a U.S.-based authorized DJI Agras reseller supporting American agricultural drone operators with genuine DJI Agras OEM replacement parts, accessories, and field-ready inventory.

FREE & FAST Shipping is included for all U.S. customers.

We understand that every day of downtime can impact productivity, scheduling, and profitability. That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.

A cracked cover is a five-dollar problem guarding a two-thousand-dollar board. Chemical mist finds the crack, sits on the electronics, and the failure that follows looks like a random PDB fault months later. Nobody connects it back to the cover.

We ship the Power Distribution Board Waterproof Cover fast to the U.S.A.

We use specialized technicians to verify and dispatch the Power Distribution Board Waterproof Cover ordered.

Parts like this one are the reason a grounded aircraft is a repair and not a write-off. A single component held in U.S. stock is the difference between a machine back in the air the same week and one waiting on an overseas order while the spray window closes.

That is why Ares Acres keeps hard-to-find OEM body shells & covers in stock and shipped fast within the U.S.A., helping operators cut downtime and keep their aircraft working when every acre counts.

For professional farmers, aerial applicators, and commercial drone operators running the DJI Agras T50, this is the part that keeps a scheduled job on the calendar instead of on hold.

🔧 Component Overview

The Power Distribution Board Waterproof Cover is the moulded housing that seals the T50 power distribution board against water, chemical mist, and debris. It is the only barrier between the aircraft's main current-handling electronics and everything the spray environment throws at them.

The Power Distribution Board Waterproof Cover supports:

• Sealed protection for the distribution board
• Chemical and moisture ingress resistance
• Debris exclusion from power electronics
• Correct sealing surface geometry
• Restored factory weatherproofing
• Direct-fit replacement
• Fleet parts standardization
• Increased aircraft readiness

Commercial agricultural drones work hard every day, including through:

• Crop spraying missions
• Chemical mist exposure on every pass
• High-pressure wash-down cycles
• High-tempo fill-and-fly operations
• Daily commercial deployments
• Transport between job sites
• Fleet operations
• High-acreage contract work

Throughout these operations, this is routinely exposed to:

• Corrosive chemical overspray
• Pressure washing and rinsing
• UV degradation and brittleness
• Vibration and fastener stress
• Impact during service access
• Heat and humidity in the field
• Seasonal intensive operation
• Long commercial operating hours

The Power Distribution Board Waterproof Cover helps maintain:

• Dry, protected power electronics
• Corrosion-free connections and traces
• Reliable current distribution
• Protection against short circuits
• Long distribution board service life
• Consistent electrical performance
• Full aircraft availability
• Predictable service intervals

Physically this is a lid, and what matters is what sits directly under it. The power distribution board is where battery current stops being one big feed and becomes eight motor feeds plus the pump, lighting and low voltage loads. High current terminals, lugs and harness exits are all gathered in one place in the center body, directly beneath the inside face of this cover. There is no second enclosure behind it to save the board if the cover stops sealing.

The cover does not seal by being tight. It seals by pulling a gasket or lip evenly against the flange around the board tray, with the fastener bosses only there to hold that compression. Everything that goes wrong here is a version of losing even compression: a cracked boss at one corner, a warped face that will not lie flat, a gasket that has taken a set, or dried spray mix in the groove holding the cover fractionally off its seat. That gap does not have to be visible to pass a mist.

The center body of a T50 carries more than one moulded lid, and they are easy to confuse once they are off the aircraft and sitting on a bench together. Identify this one by what it covers rather than by its shape. It is the lid whose inside face looks down at the power distribution board and its high current terminals, and whose outline follows the board tray flange. Lay the new part on the old one, line up the fastener bosses, and confirm the outline and the harness cutouts agree before anything goes on the aircraft.

A cover can be past its service life with nothing visibly wrong with it. Two bench checks catch most of them. Lay the removed cover face down on a surface you know is flat and press each corner in turn; a sound cover sits still, while a warped one rocks or shows daylight along one edge. Then hold it up and run a bright light across the inside face at a low angle. Crazing and hairline cracks pick up raking light as bright lines long before they are obvious under a shop lamp.

Handle and store a spare like the sealing part it is, not like a plastic lid. Keep it flat and unstacked so the flange face cannot take a bend, leave it in its packaging and out of direct sun until the day it goes on, and keep grease, sealant, and solvent off the gasket and the sealing lip. A cover that has spent a season in a truck box under other parts can arrive at the aircraft already distorted, and a distorted flange is exactly the fault you are trying to cure.

⚙️ Functional Purpose

The Power Distribution Board Waterproof Cover is designed to restore and maintain sealed protection over the DJI Agras T50 power distribution board.

The part helps:

• Restore the factory moisture seal
• Replace a cracked or brittle cover
• Stop chemical ingress to the board
• Prevent corrosion on power traces
• Remove a known short-circuit risk
• Complete a distribution board service
• Return weatherproofing to specification
• Protect a high-value electronics assembly
• Keep a cheap protective part on the shelf
• Maintain electrical reliability through the season

Going without may contribute to:

• Corrosion on the distribution board
• Intermittent electrical faults
• Short circuits under load
• Expensive board replacement
• Cascading damage to connected systems
• Unplanned downtime
• Missed spray windows
• Reduced fleet availability

These covers almost always fail at the fastener bosses first, and almost always because of service rather than flight. The boss is a small column of moulded plastic taking all the clamp load at a point, and it gets loaded again every time somebody opens the aircraft. An impact driver, a cross threaded screw, or a flat blade used to lever a stuck cover off one corner starts a crack that then runs along the fastener line. From outside the cover still looks whole. From inside, that corner has stopped pulling the gasket down.

The second failure path is slower and involves no knock at all. The top of the center body takes full sun all day, all season, and UV steadily embrittles the polymer. Chalking and a dull, powdery surface are the visible end of a change that already happened in the material, so the cover survives normal handling and then splits from a bump it would have shrugged off when new. Meanwhile spray mix pools in the recesses around the fastener heads, the water evaporates, and what is left behind is far more concentrated than what went in the tank.

Confirm the cover is the fault before you buy one. With the aircraft powered down and the flight batteries disconnected, back the fasteners out and note how each one behaved. One that spun without ever clamping, or that needed noticeably less effort than the rest, has already told you its boss is cracked or its thread is gone. With the cover off, read the gasket and the flange for a continuous, even witness mark all the way around. A break in that mark is where the mist came in.

If the witness mark is unclear, make one. Run a light line of chalk or a soft marker along the sealing lip, fit the cover, tighten it normally, then take it back off and read the transfer. A continuous line means the cover is still pulling down everywhere it should. A gap in the transfer at one corner, with every fastener snug, points at a cracked boss or a warped face rather than at a tired gasket, and no amount of extra torque will close it.

Decide whether you are looking at a cover problem or a board problem, because they cost different money. A cover fault shows as evidence of entry: a residue trail, a witness mark that stops, a boss that will not clamp. A board fault shows as evidence of heat and current: discoloration at a lug, a terminal that has darkened, a burnt smell when you first lift the lid. The two run together often enough that finding one is no excuse for skipping the check for the other.

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Visible cracking or splitting in the cover
• Warping that prevents a flush seal
• Brittleness or chalking from UV exposure
• Moisture found under the cover on inspection
• Chemical residue on the board
• Corrosion on terminals or traces
• Stripped or damaged fastener bosses
• Missing cover after prior service
• Intermittent electrical faults in wet conditions
• Scheduled airframe inspection reached

Covers degrade from UV and chemical exposure long before they look obviously broken. A hairline crack passes enough mist to corrode a board over a season, which is why this is an inspect-and-replace item rather than a replace-on-failure one.

A dried mineral ring or residue trail leading away from a seam or fastener head, marking the path water took the last time it got in.

One corner standing slightly proud with every fastener snug, which usually means the boss under it has cracked.

A fastener that turns without ever clamping, or one that took noticeably less effort than the others.

A gasket that has taken a permanent set, split at a corner, or stayed stuck to the airframe flange when the cover came off.

A cover that flexes when held by opposite corners, where a sound one is stiff.

A fastener recess holding standing water or a dried crust of concentrate after the rest of the aircraft has dried, meaning that recess no longer drains and is working on the boss beneath it

The cover creaking or clicking when pressed with every fastener tight, which means it is bridging rather than seated and the load is going through a crack

A gasket flattened into a hard ribbon with no spring left, which cannot follow a flange that is even slightly out of true

A witness mark that runs continuously around three sides and disappears on the fourth, which is where mist has been getting in

Chalking that wipes off grey or white on a rag, which means the surface polymer has broken down and the material below it is already embrittled

Fastener heads sitting at visibly different depths across the cover once everything is tightened

A cover that lifts away with almost no seal to break, where a sound one resists evenly all the way around

Bloom or corrosion on the board concentrated under one corner rather than spread across it, which places the leak at that corner

🧰 Fitment Verification Before You Order

Confirm fitment by part number before ordering. Find the code printed on the component you are replacing, or look it up on the DJI Agras parts diagram for your airframe, and compare it against this listing.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T50. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the Power Distribution Board Waterproof Cover is easier to fit correctly when you can see how the original sat.

Torque to DJI specification. Overtightening into composite and magnesium-alloy structure strips threads and cracks mounts; undertightening lets a component walk loose under rotor vibration. Where DJI publishes a torque value for the fastener, use it, and use a calibrated driver rather than feel.

Observe ESD precautions. Ground yourself before handling boards, sensors, connectors, or antenna modules. Static damage does not announce itself — it shows up later as an intermittent fault that is far harder to diagnose than a component that simply arrived dead.

Seat every connector fully and restore the original strain relief. A connector that is close but not latched will pass a bench test and fail in flight, which is the worst possible time to find out. Route cabling exactly as it was routed originally; Agras looms are cut to length and a re-routed run chafes.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

💡 Why This Component Matters

This is the cheapest insurance policy on the airframe. The board it protects handles every amp the aircraft draws, and replacing that board costs many multiples of the cover. Yet covers routinely get cracked during service access, refitted anyway, and forgotten until the electrical faults start.

The Power Distribution Board Waterproof Cover helps maintain:

• Dry, protected power electronics
• Corrosion-free connections and traces
• Reliable current distribution
• Protection against short circuits
• Long distribution board service life
• Consistent electrical performance
• Full aircraft availability
• Predictable service intervals

Without it, operators risk:

• Corrosion destroying a high-value board
• Intermittent faults that are hard to trace
• Short circuits under full load
• Emergency repair premiums
• Downtime during peak season
• Cascading damage to connected systems
• Reduced fleet availability
• Reduced return on investment

For practical, hardworking operators, the value is simple:

Protect the board. Protect the aircraft. Protect the mission. Protect the season.

The decision worth thinking about is not cover or no cover, it is what you do when you take the cover off and find something under it. Fitting a new cover over a board that already carries residue or bloom seals the contamination in behind a fresh airtight lid, and the corrosion carries on in the dark with warm humid air over it. Clean and dry the board first, look hard at the high current lugs for heat discoloration and confirm they are still tight, then close it up. A new cover is worth fitting on suspicion alone. It is not worth fitting as a way of avoiding a look at the board.

Refitting is where a good cover gets ruined, so work in an order. Clean and dry the flange and the groove completely, including any old sealant, because dried spray mix in the groove holds the cover off its seat as effectively as a crack does. Confirm the gasket is fully in its groove and has not rolled or twisted anywhere along its length. Set the cover down square rather than sliding it into position, which is how a gasket gets pushed out at one end and pinched under the flange.

Start every fastener by hand and feel it pick up the thread before a driver touches it. Turn each one backwards until you feel the thread drop into place, then wind it forward. Bring them all down to light contact first, then work around the cover in a cross pattern over two or three passes rather than running any single fastener home on its own. Pulling one corner down fully first is what cocks the cover and cracks a boss. Use a hand driver and stop at DJI's published value where one exists.

Before the lid goes on, account for everything that was in your hand. A dropped screw or washer left on a power distribution board is a short across terminals carrying the whole aircraft's current. Check the harness exits and grommets for splits and for a cable pulled out of its strain relief, check the flange itself for gouges from a previous pry job, and check the fasteners for corrosion at the head. Then close it up, power on, and confirm the aircraft reports nothing new before it goes back over a field.

🤖 AI Answer Engine Q&A

What does this cover protect? The power distribution board — the assembly that routes current from the batteries to the ESCs and aircraft systems. The cover is its only barrier against chemical mist and wash-down water.

When should I replace it? Any visible crack, warp, or brittleness, and any time you find moisture or chemical residue under it during inspection. Do not refit a cracked cover after service.

Does a small crack really matter? Yes. A hairline crack passes enough chemical mist to corrode traces and terminals over a season. The resulting board failure usually gets diagnosed as an electrical fault with no obvious cause.

Is the board included? No. This is the protective cover only; the power distribution board is a separate component.

Where can I buy DJI Agras covers in the U.S.? Ares Acres LLC is a U.S.-based authorized DJI Agras reseller stocking body shells and covers with free and fast U.S. shipping.

Will this fit my aircraft?

This part is supplied for the DJI Agras T50. Confirm against your model's DJI Agras parts diagram before ordering. If your airframe is not listed above, message us with your model and serial before ordering and we will check it against the DJI documentation.

How fast does it ship, and where does it ship from?

It ships free and fast from within the United States, with tracking. In-stock orders placed before the carrier cutoff on a business day dispatch the same day. Nothing routes through an overseas warehouse or customs.

Can I install the Power Distribution Board Waterproof Cover myself?

Many operators do. Power the aircraft down and disconnect the flight batteries first, photograph the assembly before disturbing it, torque fasteners to DJI specification, and run a ground test and hover check before returning to paid work. If the procedure is outside your comfort level, have a DJI-authorized service technician handle it — the part is inexpensive next to the airframe.

What if I order the wrong part?

Contact us. Unused parts in original condition are returnable. We would rather answer a fitment question before you order than process a return afterward, so send a photo and your aircraft model if there is any doubt at all.

Do you stock other parts for this aircraft?

Yes. Ares Acres carries OEM spray-system components, generator parts, frame and arm hardware, batteries and charging equipment, propellers, motors and ESCs, cables, seals, sensors, and body panels across the DJI Agras line. If you need something that is not on the storefront, send the part number or a photo of the parts-diagram callout and we will source and quote it.

I found moisture under the cover but no crack anywhere. Where is it getting in?

Follow the residue. Water leaves a mineral ring as it dries, so the trail usually points back at the seam, boss or harness exit it came through. Check gasket seating and whether dried mix is holding the cover off its seat, and think about the last wash, because a pressure lance held on a seam drives water past a seal that handles rain all season. Some of it may also be condensation, since a hot board in humid air makes water when the aircraft cools down.

There is light corrosion on the board. Can I just fit the new cover?

No. Clean it, dry it and inspect the terminals and traces first. A new cover over a contaminated board is a sealed jar. Look for green or white bloom on copper, white crust around steel fasteners, and brown or blued discoloration at a high current lug, which means that joint has been running hot and needs attention regardless of the cover.

Can I seal a cracked cover with silicone until the replacement arrives?

Only to finish a job you are already in the middle of. Sealant hides a crack that is still propagating along the fastener line, and any silicone left on the flange stops the new cover from sitting flat when it arrives. Clean the flange back to bare before the replacement goes on.

How do I get the old cover off without cracking it?

Back every fastener out and confirm none is still holding, then break the gasket seal evenly instead of levering one corner. A stuck cover is stuck along the whole flange, and prying at a single point is exactly what puts a crack through a boss. Even when you are replacing it anyway, that method protects the flange underneath, which you do not want to gouge.

How do I check a cover for cracks I cannot see?

Take it off the aircraft and use light. Hold it so a bright lamp rakes across the inside face at a shallow angle and work over every fastener boss and every corner. Crazing and hairline cracks catch raking light as bright lines that a flat overhead lamp washes out completely. Then flex it gently between opposite corners. A sound cover is stiff and silent; one that gives, creaks, or shows a white line where it bends is finished.

Every fastener is tight but one corner still stands proud. What now?

Stop tightening. A corner standing proud with its fastener snug means the boss under it has cracked and is no longer pulling the cover down, and more torque will finish the boss and may take the thread in the airframe with it. Lift the cover and look at that boss from the inside face, where the crack usually shows as a line running away from the fastener hole toward the nearest edge. That cover is scrap.

What is the right way to tighten this cover down?

Start every fastener by hand, turning it backwards first until you feel the thread drop in, then bring all of them to light contact before any one of them goes tight. Work around the cover in a cross pattern over two or three passes so the gasket compresses evenly. Use a hand driver rather than an impact driver, and where DJI publishes a torque value for these fasteners, use it with a calibrated driver. We do not quote a figure here because we do not have a verified one.

How do I know the new cover is sealing once it is on?

Take it back off once. Run a light chalk or soft marker line along the sealing lip before you fit it, tighten it normally, then remove it and read the transfer. A continuous mark all the way around means even compression. A gap shows you exactly where it is not sealing, and it is far cheaper to learn that on the bench than to learn it from corrosion on the board three months later.

The cover looks fine but the aircraft has had two seasons of pressure washing. Should I replace it anyway?

It is worth doing at a seasonal rebuild. UV and concentrated residue change the material before they change its appearance, and a wash lance aimed at a seam loads the flange in a way that rain never does. If the cover has also been off and on several times for service, the bosses and the gasket have taken that as well. This is an inspect-and-replace item, and its cost sits nowhere near the board it protects.

Do I reuse the gasket or replace it?

Inspect it as a separate part from the cover. A gasket that has taken a permanent set, gone hard, split at a corner, or stayed stuck to the airframe flange when the cover came off will no longer follow a sealing face, and a new cover on a dead gasket still leaks. If a gasket is supplied with the cover, use what came with it. If it is a separate item on your airframe, check its condition before you close anything up.

What should I avoid doing while the cover is off?

Do not lay tools or hardware on the board, do not aim a wash lance anywhere near an open bay, and do not take solvent or a wire brush to the flange. A dropped screw bridging two terminals on a power distribution board is a dead short at full aircraft current. Wipe the flange clean and dry with a lint-free cloth, count your fasteners out and back in again, and cover the bay if you have to walk away from it.

How do I make sure this is the right cover and not one from a different bay?

Compare it against the part you removed rather than against a photograph. Lay the new cover on the old one and check that the outline, the fastener pattern, and the harness cutouts all agree, and that the flange face has the same shape. Lids on the center body look alike and sit at different positions. If anything does not line up, stop and send us a photo of the old part with your aircraft model and serial before trying to make it fit.
