    Understanding Charging and Chargers

    Hi well i was looking at large power-supplies in general and hoping to find a good variable voltage supply, then i wanted to build a current limiter in, i didn't like the idea of fast charging the cells all of the time, especially if they had just been used. I thought it would be good to slow...

    Understanding Charging and Chargers

    Thanks for the input Fechter, it is starting to make more sense to me. It could be a bit of a gamble buying an old industrial switch mode powersupply but i guess there is always a way and hopefully i would get there eventually. It's just i'm not sure that some of the chargers for sale (for...

    For some people building their own packs out of separate cells is a good option. At least you will know how to maintain your pack and how to upgrade the pack itself. In case you want to go for more Ah or a higher voltage. The initial choice of the C rating for the cells you are going to use...
