Nitecore NL2150DW – 5000mAh 21700 Battery for the R40 v2 Flashlight
The Nitecore NL2150DW is a 5000mAh 21700 battery made specifically for the Nitecore R40 v2. The "DW" cells work only in the R40 v2, so this is the spare to buy if you carry that light.
It charges through the R40 v2 itself, either from the light's USB-C port or in the two charging docks that come with it. It has Nitecore's usual protections, including a pressure relief valve and high-temperature resistance. A second battery is handy for long patrols.
