RadioMaster 2S 7.4V 5000mah 37wh Li-Ion Battery

Highlights at a glance

5000mAh ultra large capacity: The battery life far exceeds that of ordinary 18650 batteries (2500-3000mAh), so you don't have to worry about the remote control running out of battery during long outdoor flights.

2 x 21700 high-energy density battery cells: large capacity, light weight, and better energy density than traditional lithium polymer batteries.

Official factory adaptation: designed specifically for RadioMaster TX16S/TX12/Boxer/GX12 remote controls, with perfectly matched dimensions.

7.4V nominal voltage (2S): Suitable for all RadioMaster remote control voltage requirements.

XT30 main discharge plug: can provide sufficient current for external high-power high-frequency heads (such as 1W ELRS modules).

JST-XH balance head: convenient for balancing charging in lithium-ion (Li ion) mode.

Lithium ion (Li ion) batteries are safer and more stable: compared to lithium polymer (LiPo) batteries, they are less prone to bulging and are more suitable for low current devices such as remote controls.
