Equalizer to be used for 12V batteries which are connected in series to keep battery voltage balance. When two or more batteries which are connected in-series are in charging/discharging/free status, the battery voltages may become off balance over time and different one from the other. This battery equalizer will equalize/balance battery voltages when it detects there is a 20mV difference between two batteries. It will shunt current from one battery (the higher voltage one) to the other battery (the lower voltage one) until their respective battery voltages are almost the same. This will extend battery life and improve battery performance.

Battery equalizers can be used for 24V, 36V, 48V and any other N*12V battery system.

You will need:

1 unit for a 24V system;
2 units for a 36V system;
3 units for 48V system;
