ZB2L3 18650 Li-ion Lithium Battery Capacity Tester

ZB2L3 18650 Li-ion Lithium Battery Capacity 

The ZB2L3 Battery Capacity Tester is a compact and easy-to-use electronic load tester designed to measure the capacity (mAh) of rechargeable lithium batteries such as 18650, 14500, 16340, 26650, and other 3.7V Li-ion cells.
It performs a constant-current discharge test and automatically calculates battery capacity based on the discharge time and load current.

The module uses a resistive load (external power resistor) and displays real-time voltage, discharge current, and accumulated capacity on a digital display. This makes it a useful tool for comparing battery health, verifying battery quality, and evaluating cell performance.
