So I bought a trailer, and I'd like to put a small winch on said trailer for yarding broken rigs and such onto said trailer. My first idea was to simply throw a battery box inside the toolbox on the front tongue, and remember to charge the battery before needing it.
However, that seems like a recipe for leaving me with "dead trailer winch battery" at the times I would most likely use it.
My trailer has a breakaway box, and I just fixed the fused 30-amp key-on 12 volt feed that goes through the 7-pin connector, so now my breakaway box says "charging" whenever I have the truck plugged in and running.
My question... can I put a battery on the trailer and just splice into the charge wire for the breakaway box and have the battery charge from that? Or am I asking for trouble? Do I need a battery isolator? Do I need to upgrade the wiring/circuit for the 12v key-on circuit in order to charge a larger battery? Can I mount the bigger winch battery permanent, and do away with the breakaway battery altogether and just wire the breakaway switch up to the regular battery?
What's the "right" way to do it? I know there's people with enclosed trailers that have batteries and such... how do you keep those charged?
Gimme some thoughts here ya'll.
