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 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. 3S 4S 5S 6S 7S 8S 4.2v li-ion balancer board 18650 li-ion balncing full charge battery balance board Package Included: 1pcs * 18650 Balance Function Protection Board Before purchase: 1.
