    As close as possible & practical. However NOT inside a small enclosed space WITH the battery where gas could build up. Although most unlikely you should never risk putting ANY electrical equipment which has a potential to create a spark in an evironment which could possibly become explosive. With AGM/Gel batteries the risk is minimal, but they can gas in some situations. The risk is far higher with wet batteries.

    Wet batteries should never be inside the vehicle.

    You wouldn't have the link by chance?

    I mounted mine above the glove box, out of sight and can be accessed easily if needed. My aux batt is under bonnet so as close as I could while remaining out of elements and engine heat. If I had a rear battery which may happen one day, I would relocate to the cargo barrier.

    Please note this is an excel spread sheet.

    Thanks to Symon from the Myswag forum for the spreadsheet, hopefully doesn't mind me sharing it here.

    I already have some decent sized cable coming from
    the Aux battery to the bullbar a run of about 500mm,
    terminating at a 50amp anderson plug. I should be
    able to wire my weather proof MPPT reg up inside the grill
    I think. Also need to change the 50 amp anderson to a fully fitted job

    Still playing with the setup on the GQ , might pee off the 20 watt and just use the 100 watt for now .
    Just have to solve the age old question of where to put the reg without running the wires too far although it looks like yours is sorted .
    Thinking that the trip to the corner country next month will let me know the problems with the system if any and then I can fix it before next years 6 month trip hopefully to the cape .
    Fancy looking Anderson plug you have there .

    Like you I have a small 10 watt panel, Im thinking that would be OK to hook up to
    start battery to keep it "busy",
    Must also figure out how to have a solar outlet at the back I have that cig,merit and guage
    for the small cut out, this would come in handy depending on the camp site,,
    position of the sun etc, somehow I need to get my Patrol fixed first.lol

    Yeah everyone's rig is setup slightly different TD , and we all have our own ideas sometimes right sometimes wrong .
    Still haven't finished my setup I'm busy doing other stuff and charging up a mates dead ride on mower battery which has gone from 5 volt and .1 amp to 11.65 volt and .78 amp after one full day on the GQ 100 watt solar and holding .
    So will keep it up for a couple more days and see if it restores the battery , I notice the equalisation charge is pulsing 16.5 volt into it to try and shock it into life .

    Well just doing a quick hunt and found the VE 75/15 with Bluetooth dongle for $195.
    Dongle is $65 alone so about a $20 saving..

    Look at this on eBay http://www.ebay.com.au/itm/391646943763
