Application
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. One battery voltage is high and one is low.     
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.
