I have a similar project to thread658-127532.
First of all, I should let you know I am looking for a cost effective way of doing this, and I have absolutely no exp. with battery charging and circuit design... But I'm handy, have done IC projects from kits.
I would like to make a custom battery pack from surplus LI-ION batteries wired together to produce a greater voltage and Ah. The batteries are 7.2 volts, 2000 mAh, and I'll probably put them in sieries and parallel to get 21.6v 4000 mAh (6 bateries). Then DC-DC converters to get my desired voltages... 12v and 20v
The batteries are quite cheap ($3 can ea.) and I've seen some universal chargers that could charge the individual batteries, but nothing that could handle the whole pack.
Is there a product I could buy? Could I build my own charger relatively easily?or reverse engineer one?
any help/thoughts would be nice!
