Hello I have bought some lithium ion batteries. From a VW e-Golf. nice Samsung 108ah batteries and 1/2 battery 55Ah The idea is to use two of the larger ones and one half unit. making 4kw .. But I am struggling to find a charger that will do this .. Does any one know how i can charge the batteries. I had heard some one had used a computer power supply and altered it? but I can't find any of that information... Any help would be great thanks as I am struggling.. I have all this power here to really push my cityel along but do not want to use the batteries till I have a charger and a BMS.. HELP!!!
