I have 4 batteries in series. I want to charge them at once with 120 volts.
Seems to me 12.6 times 4 equals 50.4
Seems to me alternators normally charge batteries at 14 volts. So, it seems to me if I charged at 60 volts DC, I would be pretty close to perfect.
So if I take 120 volts, and stick a diode in it the right direction, I'm gonna kill one leg of the AC current, and have 60 volts peak charging my batteries.
Obviously it is not this simple, so what am I missing?
