XH-M239 Lithium Battery 18650 True Capacity Tester Module MaH mwH Digital Measurement High Precision

Description:

The minimum discharge stop voltage of 18650 battery is 2.75V. In general, when the voltage is reduced to 0.875 times of the rated voltage (3.24V), it should be charged, and if it continues to be used, the voltage will drop rapidly, and it may be damaged by overdischarge, which will affect the life span. (recommended discharge termination voltage set to 3.5V)
