Nitecore NL2150DW
Replacement Battery for the R40 V2 Flashlight
The Nitecore Nl2150DW is a 21700 replacement battery for the Nitecore R40 V2 flashlight. Packed with a huge 5,000mAh energy capacity, this battery keeps your flashlight running for hours, and charges up quick without ever leaving the light thanks to the in-body USB-C charging port.
If you already own an R40 V2 or are looking to get one soon, we recommend snagging yourself a spare NL2150DW as it is proprietary, and no other 21700 cells will work.
