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.

Great for Flashlights

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

Works great in my light. Yes its a little long, but matched with proper charger its a high output powerhouse.

I have used the Klarus G15 flashlight over a year now and carry it almost every early morning prior to daylight. Even on the coldest mornings the performance is excellent. If I don’t use it on the brightest setting, I only have to charge it once every 2 weeks. Great battery, long run time.

Just bought a KT21X and wanted a spare battery for it. Love their flashlights and their batteries are the best also!
