Battery balancer operation

The battery balancer aligns the voltage between two consecutive 12V batteries. When the battery charging voltage of the 24V battery exceeds 27V, the battery balancer turns on and starts monitoring the battery voltage - the green "on/standby" LED lights up. In the case of a voltage difference, the battery balancer releases a higher voltage battery, allowing the second battery to fully charge. Two intermediate LEDs report this. A red alarm will sound if the imbalance is too high and the device cannot equalize the voltage between the batteries. If the alarm is always on when the battery is fully charged and not extinguished, appropriate measures must be taken to eliminate the imbalance. Install another balancer in parallel or charge each battery separately.
