Introduction
The BL2150U is a premium quality 21700 lithium-ion battery with 5000 mAh capacity specifically designed for high-intensity torch use.
Featuring a built-in micro-USB charging port, BL2150U makes charging easier than ever before! You can charge the battery directly with a USB cable and 5V adaptor. No extra charger is needed anymore!
Of course, it still can be charged on an external charger if desired.
The all-new Li-ion battery provides the voltage and power needed for extended runtime and higher lumen capacities than the 18650 battery.
Besides the short circuits, overcharge/over-discharge, and overheating protection, BL2150U also has three sets of overheat protection - pressure relief, microporous, and PTC cathodal block to ensure safety.
