1000ah battery , wow ,you must have had some serious suspension mods to carry that weight !! roflmao ,, easy to see its school holidays and the kids have the computer.

Still alot lighter than two batteries plus tray plus cable plus solenoid etc.
29kg from memory. And readily available from RACV etc, just not promoted as they are not standard fitment!

You wrote , 1000ah , now , no way does a one thousand ,yes that is what you wrote , a 1000ah battery weigh 29kg , as for running a 45lt engle for 4 days straight without recharging a 100AH battery you will kill the battery , do some math , 45lt Engle uses 1.9 ah per hr x 24hr x 4 = 182.4 ah ,, back to school Craig ,,,,,

Hi Craig,

there seems to be a bit of confusion over your battery size of 1000A/H. I presume you mean 100 A/H. It's horses for courses as far as a dual is concerned. I carry over 130kgs of batteries in my vehicle plus management systems and cables but then I run an 80 litre combo, a 40 litre engel and I'm out for 2 months. When I'm 200 klicks off the nearest track, I can't afford to lose my starter. If you're going to stick with one battery, then you have no doubt upgraded yours from the standard 70 type hi crank batteries that come standard in most vehicles these days. I presume also that you've moved to a deep cycle battery of sorts still with enough CCA to start the vehicle.

I would also say that you would keep a very close eye on your fridge and battery state during that 4 days out bush to ensure your battery state. I'd imagine that you run the car for a while as well to recharge? Again this requires a fair degree of knowledge and effort that you're prepared to put in and one that may not be as necessary with the degree of comfort that an auxillary battery can provide. One thing that Gezz may not know is that if you flatten or even discharge a normal vehicle battery to a certain level (despite it managing to crank the vehicle over in the morning), the battery is being damaged. Do it several times and you will severly impact the life of the battery. Standard vehicle batteries are not made for constant and excessive rates of discharge.

Gezz, I'd reccomend you have a read of member John's blogELECTRICITY FOR CAMPING. It will explain a good deal about DC power and just what your fridge will drain out of your battery.

Sorry, my mistake, just went and checked. 1000CCA.

I will admit when I am wrong! .........But in the Jack, we have been stopped without restarting car for 3 nights, I admit that all interior lights were off etc, and the fridge is wired with 6B&S (not through existing accessory plug). I have run fridge on #4 in the Paj (2010 DiD Auto) in the driveway for 2 full days without an issue as an experiment (Friday night to Sunday night).
As the new car is an auto, I will ALWAYS carry the thumper pack when we go away as well so we can run the fridge off that for extended times without hassle.

Yes the Cold Cranking Amps makes sense. I've opted for a Hydrid battery as a vehicle Aux. It's a sealed lead-acid Deep cycle that still produces 700CCA. The Thumpa is a good idea and something that Gezza might consider as an alternative to a fitted dual battery system.

Cheers Mick
