BMS (Battery Management System) – a battery management system that is designed to monitor the status of batteries, control the process of charging/discharging the battery, etc. RoboticsBD
Two batteries (18650) can be connected simultaneously to the HX-2S-D20 charge-discharge controller module. The module has protection against short circuit, overcharge and over-discharge. One of the functions of the charge controller is to turn off the power supply for the batteries when the maximum capacity of at least one battery is reached. This BMS controller is designed for more than 30,000 hours of operation. The maximum allowable current is 20 A. RoboticsBD
B+ : Battery positive pole
B- : Battery negative pole
BM : Mid-point of a battery assembly
P- : Negative charge / discharge terminal
P+ :Positive charge/discharge terminal
If the maximum permissible value of the supply voltage is exceeded, the charge controller activates the “protection” mode. In order to restore the module, it is necessary to re-apply voltage to the input of the BMS board or wait a while until the charge controller automatically disables protection.
Power is supplied to the module from an external power source. The voltage range of the module is from 7.4 to 8.4 V. For charging, you can use a step-up voltage converter with a current limiter. Please note that this module is not a charger.
