Other companies besides xs that makes 14volt battery,,, and are there any build log for cutting a hole in the truck floor and building a bank. I'm Intrested in 14 volt batteries, and building a battery compartment to house five big batteries, I'm looking for some build logs like wat Steve Meade did but a little simpler.
