Most 18650 batteries place the protection circuit on the negative base, which can be easily damaged or shorted during rough use. The SPERAS RC34 innovatively integrates the protection board onto the positive pole, significantly reducing the risk of short circuits and providing much faster reaction times against overcharging and over-discharging.
Yes! The RC34 is a standard 18650 size (3.7V) and is universally compatible with any high-drain device that accepts button-top 18650 batteries, including other flashlight brands, headlamps, radios, and cameras.
