PCB-protected lithium-ion battery with a possible 15A discharge current and components of the highest quality standards, merged into a performance battery by Keeppower. With a 15A discharge current, a capacity of 2600 mAh, a Japanese cell, and IC, the R-series is an all-rounder. The cell used is the Sony Konion (US18650VTC5), and quality components from Seiko were used for the PCB, assembled by Keeppower.

The Keeppower 18650 lithium-ion battery is PCB protected (positive terminal raised) and equipped with Seiko (Made in Japan). The protection circuit with short circuit, overcharge, and deep discharge protection is suitable for almost all flashlights. The Keeppower 18650 batteries are particularly recommended for flashlights, LEDs, mechanical battery holders, and all applications where high safety and high performance are required.

Please check the dimensions of the cell before purchasing! Due to the built-in electronics, the cell is not suitable for every application! Height and diameter are larger than a standard 18650 cell without PCB.
