I know the MINI II uses LIPO batteries but what type are used in the Remote Controller? I suspect it is NOT LIPO.

Hello there Astro Bob. Thank you for reaching out and for the inquiry. The type of battery for the DJI Mini 2 remote controller is Li-ion battery. The battery capacity of the DJI Mini 2 remote controller is 5200 mAh and it takes 4 hours to fully charge the remote controller using 18W charger. Thank you.
