Wiring a trailer battery for a winch.

[bheiting]

Purchased a 14k deckover trailer to haul whatever needs hauled.



Welded tabs to mount a third ramp in the middle so i can load rhinos, atv's ... etc. FWIW i mounted one of the ramps off my 12' trailer and it fit perfectly between the two larger ramps. :-laf



Anyways ...



I welded up a winch mount and want to mount a marine battery on the trailer.



I ran a 10g wire from the 7 pin connector.



My question is;



How do i prevent overcharging the battery?



The breakaway kit had a small 12 volt battery with a "charger".



The charger has three wires;



Blue to breakaway switch



Red to trailer battery



Black to vehicle +



this is apparently a voltage regulator to the trailer battery



can i just switch the small battery out for a marine battery and use it for the winch?



thanks

When I got my Four Wheel Camper(slide in truck camper) they wired in a heavy gauge cable from the truck battery to the truck bed. Near the battery is a battery separator. When loaded, the camper is connected with, what appears to be, a 12V trolling motor plug. Any decent RV service center should be able to advise you and provide the correct parts.
