Description: 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. Note:The balancing board must need BMS to use together and the BMS is without balancing function Specifications: 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. 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 3S Cnnection instruction: B4+ Without connection B3+ Connect battery positive; B2+ Connect the point between battery 1 and battery 2; B1+ Connect the point between battery 2 and battery 3; B- Connect battery negative; 3S balance board can use as 2S Size: 2.1x2cm/0.83x0.79inch Quantity: 1 Pc Note: Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid Due to the difference between different monitors the picture may not reflect the actual color of the item.
