18650 Li-ion Lithium Battery Capacity Tester ZB2L3

Description

 18650 Li-ion Lithium Battery Capacity Tester ZB2L3

The first test should be fully charged battery.
2. Connect the battery and load, use micro USB power supply (do not use desktop or laptop USB power)
3. Direct start test need only one press of the “OK” button, the tester can automatically develop an appropriate termination voltage of the battery full charge voltage, and will start flashing after the test three times. Need to develop artificial termination voltage only when the battery voltage display state by pressing “+” or “-” buttons to modify the termination voltage display beginning with P, behind the representative voltage resolution 0.1V, set up after pressing the “OK “start testing.

Error codes and their meanings:
Err1: battery voltage is above 15V
Err2: battery voltage is lower than the termination voltage
Err3: Battery can not afford to load or discharge current line too much resistance
Err4: over-current (current exceeds 3.1A)
