HX-JH-001 / 18650 BMS for (3S / 4S) config

The balance board is suitable for the li-ion battery pack (4S or 3S).

Note:The BMS is without balancing functio!

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 is activ, each series battery must have the same voltages. When ONE cell voltage get 4.2V, the other cells are not, the first cell voltage will discharge to wait the other cells rising to the same level.

4S Connection instruction:

B4+ Connect battery positive;

B3+ Connect the point between battery 1 and battery 2

B2+ Connect the point between battery 2 and battery 3

B1+ Connect the point between battery 3 and battery 4

B- Connect battery negative
