Re: [EVDL] LED Taillights - a money saver in gas cars? - >rangeextenderin EV's? - an

The PC supply I'm looking at here does 25 amps at 12 volts (300 watts), and
it's better than average. I don't know what it would take to raise the
voltage, control overcharging, and make it run off of a DC input. Maybe it
could supplement the aux battery, maybe with the addition of some alternator
regen during deceleration, to the point a large DC/DC is not required.
Might be able to find a 12 volt only "brick" type supply surplus someplace.
