So does the vehicle's regulator "protect" the battery ? I'm guessing
that the length of the cable from vehicle generator/alternator to the
trailer battery is enough to drop the charge voltage down to where the
trailer battery doesn't get enough voltage to boil it. In effect, a
trickle charge. Unless someone has rewired it with a fat cable.
Always willing to learn,
