Who makes the Nitecore NL2150HPi-21700 battery? (i4000r flashlight/f21i powerbank)

Nitecore that seems to use a proprietary 21700 battery that is meant for their i4000r flashlight or F21i powerbank. The main quirk is that it seems to have + and – terminals on BOTH ends of the battery. Nitecore obviously isn’t producing these themselves, and they want $25+ per battery for replacements.

Mostly looking to see if I can source cheaper alternatives for the future to make it worthwhile.

“Nitecore obviously isn’t producing these themselves”

Not sure

Not Nitecore but it’s same, you can put + and - or Piña Colada distributor and what you want on the circuit.
Nitecore put + and - on the circuit top and no Piña Colada distributor :frowning: .
But if anyone found Nitecore equal cells cheaper, I take too. since TM03 I wait :smiley:
