24v battery equalizer hao1
when two or more batteries connected in series or parallel charge and discharge, voltage differences begin to occur.
while some batteries are overcharged, others may be undercharged.
batery equalizer wili equalize/balance the battery voltage when it detect there are 20mv between two batter is. 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 lifetime by at least additional 2 yrs
