5s Placa De Proteccion 21v Pack 18650 Sin Proteccion Carga/desc Itytarg

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.
