Heltec BMS - active balancer 3-4S 5A

The principle of operation of this balancer is to transfer charged particles by means of a capacitor which is connected to the battery by the BMS, thus starting the balancing process. This balancer is equipped with a new ultra-low internal resistance MOS that allows efficient balancing of battery voltages. The board is made of PCB with 2oz copper thickness, which ensures reliable operation. The balancer allows you to adjust the balancing current from 0-5A. The more balanced the batteries are, the less current is needed.

The balancer is equipped with a manual switch for sleep mode, where the current consumption in sleep mode is less than 0.1mA. The accuracy of the balancing voltage is better than 5mV! The quiescent current of the balancer is approximately 12 mA. It is recommended to use the balancer for battery capacities in the range of 60-300 Ah. The balancer is equipped with undervoltage protection, which automatically stops the power supply when the voltage is lower than 3.0V. Standby power consumption is less than 0.1mA. With this active balancer from HELTEC, you can be sure that the batteries will be balanced, contributing to their longer life and optimal performance.
