DJI O4 Relay Specifications: 8 km FCC Range, 6500 mAh Battery & Frequency Bands (Canada)
🇨🇦 CANADA — DJI O4 Relay Specifications: Frequency Bands, Regional Power Limits, Transmission Distance & 6500 mAh Battery for Canadian Operators
🇺🇸 Reading from the United States? See the U.S. edition: DJI O4 Relay Specifications: 8 km FCC Range, 6500 mAh Battery & Frequency Bands
This Canadian edition is written for Canadian DJI Agras operators in the orchards and vineyards of the Okanagan, Niagara and Quebec’s fruit belt. It covers the 2.4/5.1/5.8 GHz bands, regional EIRP limits, maximum transmission distances by region and the 6500 mAh battery, with the regional-label vocabulary DJI uses left intact. The procedure, specifications and warnings below are identical to the original edition linked above — the hardware does not change at the border. What changes for a Canadian operator is the regulatory and purchasing context: the aircraft this DJI O4 Relay supports falls into Transport Canada’s medium RPAS class (25–150 kg) and flies on an Advanced Operations pilot certificate under the November 2025 rules, with a Special Flight Operations Certificate for anything outside that envelope, and pricing is shown in Canadian dollars. Ares Acres stocks the O4 Relay signal repeater system and antennas referenced in this guide as genuine DJI Agras OEM parts, ships them to Canada with free standard shipping, and shows CAD pricing at checkout.
DJI O4 Relay User Guide v1.0 publishes the radio bands, region-specific transmitter power limits, region-specific maximum transmission distance, power consumption and internal-battery capacity.
Quick Answer: The manual lists 2.4000-2.4835 GHz, 5.150-5.250 GHz and 5.725-5.850 GHz operating bands. Maximum transmission distance is 5 km SRRC, 4 km MIC/KCC/CE or 8 km FCC under unobstructed, interference-free conditions at a flight altitude of 2.5 m. Power consumption is 10 W, and the internal battery is Li-ion, 6500 mAh.
Operating frequency
The guide lists three frequency ranges: 2.4000-2.4835 GHz, 5.150-5.250 GHz and 5.725-5.850 GHz. DJI notes that 5.8 GHz is unavailable in some countries and tells users to check local regulations.
Transmitter power (EIRP)
| Band | Manual-listed EIRP |
|---|---|
| 2.4 GHz | <33 dBm (FCC), <20 dBm (SRRC/CE/MIC) |
| 5.1 GHz | <21 dBm (FCC/NCC), <23 dBm (CE) |
| 5.8 GHz | <33 dBm (SRRC/FCC), <14 dBm (CE) |
Maximum transmission distance
| Region/system | Distance |
|---|---|
| SRRC | 5 km |
| MIC/KCC/CE | 4 km |
| FCC | 8 km |
These values are not a promise of field range in every environment. DJI states that they are measured unobstructed, free of interference, and at a flight altitude of 2.5 m.
Power and battery
Power consumption is listed as 10 W. The internal battery is Li-ion with 6500 mAh capacity.
Field placement still matters
The operating section separately recommends placing the relay at least 2 m higher than the crops and keeping the antennas unobstructed. Those field instructions should be considered alongside the laboratory/standardized range statement.

Canadian Operator FAQ: O4 Relay Specifications
Does Ares Acres ship the O4 Relay signal repeater system and antennas to Canada?
Yes. Ares Acres ships genuine DJI Agras OEM parts, including the O4 Relay signal repeater system and antennas referenced in this guide, to Canada with free standard shipping, and Canadian customers see CAD pricing at checkout.
Do I need an SFOC to use the DJI O4 Relay with my DJI Agras in Canada?
The DJI O4 Relay itself needs no aviation authorization. The DJI Agras aircraft it supports falls into Transport Canada’s medium RPAS class (25–150 kg) under the November 2025 rules and is flown within visual line of sight on an Advanced Operations pilot certificate; a Special Flight Operations Certificate is still required for operations outside that envelope, such as beyond visual line of sight or payloads Transport Canada treats as dangerous goods. Confirm current requirements with Transport Canada and your provincial regulator before operating.
Is this specification reference different for Canadian operators?
No. The specification reference described here is identical in every country; only the regulatory framework, the purchasing path and the units used in this guide differ. Confirm current requirements with Transport Canada and your provincial regulator before operating.
