Good quality assembly. The circuit control are 3 x DW01-P battery protection. This IC is designed to protect lithium-ion/polymer battery from damage or degrading the lifetime due to overcharge, overdischarge, and/or overcurrent for one-cell lithium-ion/polymer battery. - Overcharge detection voltage: 4.250±0.050V cut current charge and release at 4.050±0.050V. - Overdischarge detection voltage: 2.40±0.1V cut current discharge and release at 3.0±0.1V. - Overcurrent detectio voltage 150mV±30mV through shunt resistor 0,025 Ohms and 1K resistor conected to the 3 x DW01-P sense pin. The 1K resistor define de overcurrent voltage of DW01 to aproximated 25A limit. If need less current recalculate de sense resistors. Balancer circuit are comparator that detect voltage diference of 3 batterys and discharge the batterys thru 680 Ohm resistor. Simple design circuit. You have to check the voltages to see that the tolerances of the safety parameters of the batteries are met. I have verified all this in diferent conditios and work well for this chienese circuit whith her limitations. This circuit not control the current of charge and need the external circuit of charge adequate.Read full review

The product does not have a balancing function! When one of the maximum voltage is reached, the protection is triggered and the remaining batteries remain undercharged.

It does not have any mounting holes nor any data at all, except how to wire it up as shown on the web site. No information about what the two pins T1 and T2 are for. A schematic would help or at least tell us what they are for.

I'm really positively surprised with this item. I tested it for overvoltage, cell balancing with good results. I have not done short test yet.
