Next-Generation 5500mAh Battery
From Nitecore's latest battery generation, the NL2155HPi stands out with an impressive 5500mAh capacity, making it an excellent choice for high-drain devices thanks to its continuous 20A discharge current. Compared to its predecessor, the NL2150HPi, the NL2155HPi features a bigger capacity and a bigger discharge current. The NL2155HPi is part of Nitecore’s upgraded i-Series line, offering enhanced performance while remaining fully compatible with existing i-Series flashlights that use 21700 batteries. Featuring Nitecore's hallmark safety standards and precision engineering, the NL2155HPi reinforces the brand's reputation as a reliable source of rechargeable Li-ion batteries.
Premium Build with Safety Features
The NL2155HPi incorporates a built-in intelligent protective circuit and a pressure relief valve, safeguarding it against overcharging, over-discharging, and short circuits. Crafted with top-tier materials, such as nickel-plated stainless steel protectors that fortify it against impacts, ensure efficient conductivity, and fend off oxidation, the battery is further coated with a durable metallic film, bolstering its resilience against abrasion. Designed for longevity, it can withstand over 500 full recharge cycles, making it both cost-effective and environmentally friendly.

What People Are Saying
Mitchel K.Fenix HMR65R-T V2.0 Review
Super stoked on the new V2.0 version of this headlamp. The new ratchet system is a great improvement. The update headband is fantastic. And the purple colour scheme is super cool. I’ve owned multiple Fenix lights over the past few years and I won’t consider any other brand for future purchase. Happy customer.

Rob M.Pocket size protection
There are five reasons why I purchased this Klarus XT1C flashlight. It can be programmed for one button instant strobe. One,Defense from bears or people. Two, Offence, red light keeps you hidden at night. Three, USB-c battery usually an upgrade. Four, small pocket sized and five, Klarus is a good brand name.
