DJI O4 Relay long term storage and maintenance guide

DJI O4 Relay Storage & Maintenance Guide: 30-50% Charge, Hibernation & Six-Month Recharge

September 17, 2026

The O4 Relay has an internal Li-ion battery, so storage requires more than simply powering it off. DJI specifies storage temperature, state of charge, hibernation recovery and a periodic full-charge interval.

Quick Answer: For storage longer than three months, keep the relay from -10°C to 30°C (14°F to 86°F) and store it at 30%-50% battery level. Do not store it fully discharged. If the battery enters hibernation after deep depletion, recharge it. DJI instructs users to fully charge the battery at least every six months to maintain battery health.

Long-term storage temperature

For storage longer than three months, DJI recommends an environment from -10°C to 30°C.

Store at 30%-50% battery level

DJI recommends storing the relay between 30% and 50% for extended periods. Do not store the battery for a long time after fully discharging it, because over-discharge can permanently damage the cells.

Recover from hibernation by charging

If the battery is depleted and stored for an extended period, it can enter hibernation mode. Recharge the battery to bring it out of hibernation.

Fully charge at least every six months

Unlike some manuals that use vague maintenance wording, this O4 Relay guide gives a clear interval: fully charge the battery at least every six months to maintain battery health.

Keep the relay dry and assembled

Store the product in a dry environment. Do not detach the antennas during storage, and make sure the USB-C port plug is securely fastened.

Avoid heat and do not disassemble

Do not leave the product near furnaces, heaters, direct sunlight or inside a hot vehicle. DJI also warns not to disassemble the product because the internal battery may leak, catch fire or explode.
