AC Input to DC Chargers

[Brian Young]

Yep, Im planning to do that. One of my chargers
specified a 13 amp supply to meet its max output
rating.

Another thing, Im finding that my car battery doesnt
have the duration it once did. I used to charge my RC
batteries at the field, but have been supprised
recently by a dead battery when Im trying to go home.
Has anyone put heavy duty batteries in your car to
compensate for this?
