I know many of you couldn't give a flying F**K about lithium ion battery charging but I'm really sick of using lead acid batteries to store my solar and wind energy, they suck !! Now I have a stack of lithium ion batteries pulled mostly from old laptops, now I'm sure a li-ion battery bank would be much better, hence the need for a charger that works off of my wind generator and solar panels.
Lithium-ion batteries for off grid systems
This is about the simplest li-ion battery charger I could find on the net, I've put together quite a few of them and found this one to be what I've been looking for.
I'll be using this design to do 4 cell parallel charging, the LED's on each cell are an added bonus showing me when a bank of cells is fully charged.
