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, smart locks and powerbanks & battery packs.
