I am assuming that you have more than enough to build you own chargers. However, even for the cheapest one (that I know of), the components would cost more than buying one. Here is the one I built a few years ago cost me about $28 (not counting the redesign). You can buy a real simple one from HK for your lipos (just hook the Lipos up in parallel-or make a current limiting circuit from spare parts). Heck, it would cost you that much in gas just to go get any parts (I think).
I am anxious for you to build your own because of all that you might learn. Let me know your plan. TIA

P.S. I am sure that you already know that the TL431 shunt regulator is adjustable to whatever your needs are.
