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

Features:

1) high-accuracy voltage detection circuit;

2) terminal of the charger using high voltage device;

3) Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit);

4) MOS transistor can control the battery charge and discharge;

5) low standby current consumption.

Brief Parameter:

5S 100A 21V LMO

1.This protection board is 3s 4s 5s in common use lithium battery protection board (you can adjust for how many strings to be used), the default delivery is 5S ternary lithium.

2.Specified chip, stable performance, support disconnection protection, over-current protection, over discharge protection, overcharge protection, with balance, etc.

3.Common use for “same port” and “different port”, the protection board uses 15 high-power of ultra-low resistance MOS tube (discharge of 8, charging of 7), in the same port mode can support the discharge current 60A, charging current 60A; different port mode discharge current 80A, charging current 60A.

4.Can use for LMO.Ternary lithium battery.LCO(3.7V)battery packs etc.
