7S BMS Balancer Lithium Li-ion 18650

4.2V Battery Protection Board Balancing

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.

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.

Parameter:

• Balance

Voltage for each single cell:

4.2V

• Balance

current for each single cell

:66mA

• Size:

L37.5mm*W26mm

Note:

• The balancing

board must need BMS to use together, and the BMS is without balancing

function

• 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
