Powertac 3200mAh High-Discharge 18650 Rechargeable Battery

Powertac 3200mAh 18650 – High-Discharge Power with Built-In Protection

Not all 18650 batteries are equal. The Powertac 3200mAh High-Discharge 18650 is built specifically for high-drain devices like tactical flashlights — with an internal PCB protection circuit that prevents over-voltage and under-voltage damage, extending both battery and flashlight life. At 11A continuous and 15A pulse discharge, it delivers the current that high-lumen lights demand without voltage sag.

Why PCB Protection Matters

Unprotected 18650 cells can over-discharge below safe voltage levels, permanently damaging the cell and potentially the device it powers. The Powertac 3200mAh includes an internal protection circuit that cuts off at 2.5V (under-voltage) and 4.2V (over-voltage), keeping the cell within safe operating parameters on every charge cycle.
