I brought this charger/balancer form Banggood T610 - https://goo.gl/KLukPU and i am very happy. But what about over-discharge protection? So, i brought this 3S protection board. I have tested the cutoff voltage and it is at about 2,33V. This is ok if you are draining your batteries with high current, because you have a fair amound of voltage drop. But it is low if you are using low current. You have to apply charging voltage to overide the "lock" after the over-dischard cutoff and the voltage must be above 2,9V in each battery to do that. I also did the some tests to this 2s protection board https://goo.gl/kJ4qX4 and it is really good and cheap.
