RC34 18650 3400mAh Rechargeable Lithium Battery

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.

You can charge the RC34 directly inside your SPERAS flashlight if it has a built-in USB charging port. Alternatively, you can safely use any high-quality external lithium-ion battery charger (such as the SPERAS ALL4 or NL8 chargers).
