You could buy them if you need cheap batteries where you dont care about real size and weight vs capacity but otherwise pass

Recharging them only put in 5000 to 5100mah in them and remember that capacity has to be less than the amount of energy that you pushed in not equal to it

In other words those cells are not the rated capacity and when i discharged them they didnt seem that well balanced some cells dipped low before others

I didnt try them under real load because i dont plan on using them since they fall short of the rated capacity
