Elevate your Autel Robotics Alpha flight time with this Autel Alpha Battery Kit. The Alpha is the first drone in the Autel quadcopter series to adopt a dual-battery design which can provide an additional 40+ minutes of flight time. Autel Alpha Dual Battery Design With the dual-battery design of the Autel Alpha, the batteries are inserted in the tail of the aircraft and arranged side by side. The batteries are hot-swappable, with a maximum flight time of 48 minutes. The duration of pulling lasts about 30 seconds. Autel Dual Battery Design Considerations With a dual-battery design, firmware version of both batteries must be the same. Always use the batteries in pairs to extend their lifespan, and paired batteries must be charged and discharged together.
