บาลานซ์บอร์ด 4s 4.2v 66mA สำหรับแบตเตอรี่ลิเทียมไออน(Li-ion) ถ้าไม่เข้าใจการทำงานสอบถามได้

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 4.2V
กระแสการ Balance :66mA
ขนาด: 25mm X 22mm
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.
