Adding another battery under the hood question

Maybe not.

There may be only ONE battery now for everything.

Anyway, if there ARE two individual batteries now, most people boost their house capacity by adding a battery in the house section, NOT under the hood of the truck.

And that initial story about burning something up with a battery that is too high a capacity......is total bunk.
