Charging and use

Charging
  • Always use a manufacturer-approved charger, never a wall or car outlet directly.
  • Don't charge near flammable materials or on carpet or wood.
  • Never leave a battery unattended while charging.
[1]
Temperature
DJI's M300 battery is rated for use from −20 to 50 °C; below 15 °C it self-heats when installed and powered on. [1] Skydio lists X10 battery charging from 5 to 45 °C. [2]
Handling
  • Don't install or remove a battery while the aircraft is on.
  • Don't place batteries on conductive surfaces or loose in a pocket or bag.
  • Keep terminals clean and dry.

Cycle life
DJI rates the M300 battery for 200 cycles and does not recommend use after that. Check your own model's rating. [1]
Fire
DJI says to put out a battery fire with sand or a dry powder fire extinguisher. [1]
Long term

Storage

Pro tip
Follow the storage temperature
Skydio lists X10 battery storage at −20 to 45 °C for under 3 months and 25 ± 3 °C for longer. [2]

Shipping and travel

Watch out
Don't ship batteries for repair
Ohio Drone Repair asks you to keep batteries with you: they aren't needed to start, and they are a shipping hazard. [3]
Good to know
Flying with drones
The FAA notes lithium batteries can be classified as dangerous goods when you travel with a drone; check your manual and airline first. [4]
