Product description

Wuben 21700 protected high-drain battery

4800mAh with up to 20A of discharge, enough for high-drain flashlights running on Turbo modes without the voltage sag a weaker cell would show under that load.

Overcharge, over-discharge and short-circuit protection are built into the cell, specifically matched to WUBEN's own A21 and TO50R flashlights, and compatible with most other devices built for 21700 cells, solar lighting systems, fans, gimbals and bike lights among them.

Specifications

  • 21700, 4800mAh, 3.7V
  • Up to 20A max discharge
  • Overcharge/over-discharge/short-circuit protection
  • Matched to WUBEN A21, TO50R

A solid pick for outdoor workers, night guards and anyone who needs dependable runtime rather than a cell that quietly underperforms its stated capacity. The WUBEN 18650 is a smaller-format cell with built-in USB charging.
