The balance board is suitable for the li-ion battery pack BMS WHICH without balance function,so as to equalizing charge lithium battery charge function, make the battery pack each series charge at the same time.
Note:The balancing board must need BMS to use together,and the BMS is without balancing function
Parameter:
Balance Voltage for each single cell: 4.2V
Balance current for each single cell :66mA
Size: L25mm*W22mm
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.
Note:
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.
Note:the balancer starts balancing when the one cell get 4.2V, The Cut-off Voltage is according to the BMS setting,but the bms cut-off voltage needs more than 4.25V which is much better.
