GoPro Enduro Rechargeable Li-Ion Battery

A 1720mAh Enduro cell — GoPro’s cold-weather battery, and worth buying even if you never shoot in the cold.

It holds usable capacity down to 14°F where a standard battery gives up, and charges around 13% faster, so the turnaround between takes is shorter.

More recording time per battery means fewer swaps, which matters most when the camera is sealed inside a housing or strapped to a helmet and getting to it is a job in itself.
