Description
4S-30A: 4 Series 30A 18650 Lithium Battery Protection Board 12.8V with Cable
BMS (Battery Management System) is designed to monitor the status of batteries, control the charging/discharging process, etc. Four LiFePO4 18650 batteries can be connected to the HX-4S-F30A charge-discharge controller module at the same time.
The module has short-circuit, overcharge, and over-discharge protection. One of the charge controller's functions is balance charging.
