The 3S 18650 Lithium battery charger and balance protection board is a charging and protection module for 3 pcs Lithium batteries pack. It is highly integrated and can be used as portable power bank.
With MPPT charging ICs equipped, this board works as charger and supports 15-24V power supply for charging. Four indicators are equipped as battery status reminder.
The Lithium battery charger and balance protection board works constantly to monitor each cell’s voltage, the current of charge or discharge, and the temperature of the environment to provide overcharge, over-discharge, overcurrent and over-temperature protections, etc.
The battery charger and balance protection board is designed for 3 pcs 18650 Lithium batteries in series, which aren’t included in the package. You need to prepare the Lithium-ion batteries with 3.6V typical working voltage and 4.2V overcharge protection voltage. Besides, any other batteries especially LiFePO4 battery are prohibited.
