5S 21V 4.2V Balance Function Protection Board 68mA 5S Li-ion Lipo Lithium 18650 Balanced 3S 4S 5S 6S 7S 8S
The balance board is suitable for the li-ion battery pack BMS WHICH without balance functionso 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 togetherand 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 chargingeach 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 settingbut the bms cut-off voltage needs more than 4.25V which is much better.
