The battery equalizer is used for the 12Volt Flood/AGM LeadAcid Batteries which are connected in series to keep battery voltage balance. When two or more in series connected batteries are in recharging/discharging/free status.The battery voltages maybe become different. One battery voltage is high and one is low. The battery equalizer wil equalize/balance the battery voltage when it detect there are 20mV between two batteries. It wil shunt curent 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 perfomances and extend battery's using time.

Features:
Extend battery using time.
Reduce battery repalcement, save time and money.
Seal housing design, firm and stable to use.
Insulation component, safer in use.
