Klarus 21GT-50 21700 Battery

5000mAh | 15A Discharge | Button Top

Klarus comes out with some of the most power-packed cells on the market, and their first ever 21700 sized cell is no exception. The Klarus 21GT-50 is only larger than an 18650, but boasts nearly double the power at most with an impressive 5000mAh capacity. The 15A drain will take care of most high-drain devices, and can charge back up to 100% over 500 times within 2 hours. The built-in PTC keeps you and your devices safe against over-charge, over-discharge, over-current, and short-circuit accidents. Klarus recommends this 21700 battery for compatible flashlights, powerbanks & battery packs.

Spare battery
December 23, 2022
Expect this spare should last as long as the original.

Not as good as past
March 14, 2022
I have ordered this battery several times from this website and never had a n issue this is the first time that the battery performance is not good at all in the past the battery lasted 3 days with this one I am lucky to get a day and a half. And charging time has doubled. I am disappointed but I am going to try to order another one and see if I have the same issues maybe it was just one bad battery.

Great for Flashlights

I run these batteries in my Jetbeam lights. They seem to shine brighter and longer than the original 5000mAh batteries.
