Description
The only compatible high-drain 21700 battery for the KR-S40 and KR-S80 strobes. The high-drain specification is critical — strobes require rapid discharge for flash recycling, and standard 21700 cells cannot deliver the current needed. Using the correct high-drain cell ensures reliable recycle times and full-power output across a full dive.
Compatible With
Note: This is the high-drain version for strobes only. Kraken video lights use a different 21700 cell — do not use this battery in video lights.
