Li-ion 18650 / 21700

Looking for ultimate battery life? Consider the 21700 / 18650 lithium-ion battery packs. They sacrifice short-term burst power in exchange for extended running time. These battery packs are perfect for slow-peed cruising, mountain diving, and cinematic exploration when paired with a GoPro or DJI O3 Air. 
However, for  FPV and RC car racing, high-discharge LiPo cells are the preferred choice.
