Single battery system

[spinner]

I was wondering if it is possible just to run a bigger battery instead of running a dual battery system. I would like to keep the space behind the battery free to put an ARB compressor in the future. I currently run a uhf, 100w spotlights and have a 12v socket put in the rear tray. I also have a cheap fridge that I plug into the rear 12v plug but only have it plugged in whilst driving to a camping location then I run it on gas. Should I be looking for a battery with bigger amp/h. I am not all that electricaly minded so any help would be great.

Your alternator/battery will handle that without even blinking. When you need to change the battery you can consider going up a size or two or as big as you can fit. I only run a single battery because the space behind is taken up by the cruise control and have never had a problem although, like you, I don't run a fridge except when the engine is running.

Page 20, not sure how it would be for the spot, but for a 50L waeco it could power it for 6 days easy.

You should have no trouble running a larger battery in the same spot. You will need to obtain a battery tray though. The plastic one mitsi's supplied won't hold anything larger. Some guys here fit 2 batteries there by moving the cranker forward towards the power steering. If you do this, it will give you more room for the compressor behind your single battery.
