I'm planning to upgrade the winch on my trailer, which will also entail putting a full size deep cycle battery onboard. I'm failing at finding high amperage DC battery chargers, just the 800mA units for breakaway batteries. If I draw down this battery winching a dead pile on flat tires 100' and up onto the trailer, I don't want it to take a month to get the battery back up to full power.
Is there something in between the $300-500+ full RV inverter systems that have a ton of features I don't need (like shore power charging, built in inverters, etc) and the $8 throwaway 800mA and less "maintainer" type changers?
--- Update to the previous post...
Figures, I finally find something right after I post. Twice the price I was hoping for, and I'd need to figure out a proper mounting location since these are very much unsealed units, but this is the sort of thing I'm looking for
Finally found something close to what I'm after, and probably within the limitations of the "trailer" aux power circuit without having to run additional plugs, nor will it draw down my main batteries when the truck is shut off since it doesn't start charging until 13.1v.
