Hey all, as the title says, I've finished my dual battery setup. I must say I'm very impressed with the way it's working, the main battery voltage just stays a lot higher now (doesn't drop below 12.5 ever), and the second battery powers the fridge beautifully. I started running the fridge on full blast this morning at 10am, so I'll see how long it is before it cuts out. I've also wired it up in such a way that I can flick a switch and join the two batteries when I want to. Otherwise it's all automatic, the solenoid joins the two batteries if the starter battery has gone above 13.2 volts, and separates them when the main battery has dropped below 12.4 volts. So yeah, I'm a happy camper!
Here's some pics.
^ The Starting Battery
^ The Battery Separator (aka 'Smart Solenoid')
^ The mass of wiring, all this is for the stereo, lights, and dual battery
^ The main battery volt guage
^ The second battery volt guage
^ The second battery lives under that little trap door
^ What it looks like under the trap door
^ The Second Battery
^ The main reason for the dual battery
^ The all important chilled goodz to keep The Goodz refreshed at all times and to keep his meat chilled for the all important BBQ
