Energy transfer 24V 48V Lead acid lithium battery bank equalizer balance charge

Battery equalizer HA01 is used for the 12V lead-acid batteries which are connected in
series to keep battery voltage balance.
When two or more in-series connected batteries are in charging/discharging/free status.
The battery voltages maybe become different. 
The battery equalizer will equalize/balance the battery voltage when it detect there are
20mV voltage 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 battery voltage
almost becomes same. This will improve battery’s performance and extent battery’s life
time.
Battery equalizer can be used for 24V, 36V, 48V and any other N*12V battery system.
