trailer battery charging
Moderator: -Scott-
If your vehicle is allready equipped to charge a second battery then you would only need to switch off your second vehicle battery and switch on your camper battery, otherwise the best way would be have a hotwire from the vehicle to a setec or similar in the camper to charge it's battery.
Another way is buy an inverter, power it from a hotwire then use it to run a 240v battery charger.
Hope this helps.

Re: trailer battery charging
Yep, that's fine. Use a fairly heavy guage cable, probably 8ga or lower and make sure you fuse that line close to the power source and use a fuse/breaker of lower rating than the wire used. (ie Cable rated at 50amp, fuse/breaker at 40amp or less). You will get a fare voltage drop because of the length you are running so cable the heavier the better.pro093 wrote:i have a dual battery set up just wondering if i could run a set of wire,s

Otherwise, you maybe could use a 12v regulator like used with solar panels and use lower gauge cable and more or less trickle charge the trailer battery. Not too sure on that one, would require more research.
Umm .. no. That's very inefficient, expensive and pointless.Lucky Phil wrote:Another way is buy an inverter, power it from a hotwire then use it to run a 240v battery charger.

Do not do this with the vehicle in motion. 240V running between trailer and vehicle could pose a SERIOUS risk to rescue personnel in the event of an accident if any wiring gets exposed.Lucky Phil wrote:If your vehicle is allready equipped to charge a second battery then you would only need to switch off your second vehicle battery and switch on your camper battery, otherwise the best way would be have a hotwire from the vehicle to a setec or similar in the camper to charge it's battery.

Go with a double fused heavy guage wire connected with Anderson plugs at the trailer hitch, like most of the caravanning fraternity use. If need be, someone else can recharge your battery, or you could help out by recharging someone elses.
