3S 4.2v li-ion lipo balancer board balncing board full charge battery balance board with free shipping with Equilibrium
The balance board is suitable for the li-ion battery pack without balance functions,so as to equalizing charge lithium battery charge function, make the battery pack each series charge at the same time.
Balance Voltage for each single cell: 4.2V
Balance current for each single cell :66mA
Balancer is just a Auxiliary function, The balancing means when the battery charging,each series battery need with the same voltage.when ONE cell voltage get 4.2V ,the other cells not, the first cell voltage will discharge to wait the other cells rising to the same level.
battery internal resistance differences within 5 milliohm, voltage within 0.03 V voltage, capacity vary within 50 ma
Cut-off Voltage is according to the BMS setting.
