Today a mate and I went to a Mitchells camping store in Darwin, We were picking up some new gear for my tours this year.

Well Mal owns a camping hire business, he noticed a Waeco D/S battery unit that the sales man couldn't tell us about.

All he could tell us is you can run your fridge, jump start you car, and run this and that.

When asked about how long it could keep a fridge running for all we got was a blank face.

Has anyone used one of these things and can you run any fridge on it how long can it be run at any one time etc?

My mate would appreciate any replies.

Cheers Steve.

Hi Steve

Was it one of these small 32 amp units ?



It will run your fridge for about 15 hours max.

Hey Derek,

the solar unit arrived in good order. Very impressed. Thanks for that and all your advice. Can't wait to get out and use it.

Cheers. Mick O.

Steve,

it sounds like their deepcycle 35 amp hour battery unit. I picked one up the other day as part of one of their packages. Got the 50 litre fridge, mounting kit, wiring kit, thermal cover and the battery unit for $1050. Battery unit normally sells for about $299. Don't know anything much about it as I haven't bothered to unpack the box. I have seen them though and they have a digital voltmeter, several plug sockets (Merit and cigarette type) as well as pins for plugging in the charger or hooking it line with another battery. You can also connect two of them to form a 70 A/H unit. Very good construction and portable but I doubt whether it would have the grunt to crank over a diesel.

Cheers. Mick.

You need to know the Ampere Hour capacity of the battery, the total load (the total cuurent draw of the frig, lights and anything else that you intend to connect to it and the likely duty cycle of the frig (how long it is going to run in time in a 24 hour period).
As an example the battery capacity might be 80 ah, the frig might draw 5 amps and the duty cycle is 30% (or 8 hours in 24). Multiply 5 x 8 to get 40 (ah) which is the total load in 24 hours (half the battery capacity)
BUT the frig will only run until it reaches the low voltage cutout at about 11 volts so you need to know how much power you can take out of the battery until that 11v point is reached.
In the example above I'd hazard a guess at about a day and a half.

Steve,

To the best of my knowledge the Coolpower RAPS 36 power pack is the only one available from Waeco. If you need more power you need to couple them together.

Waeco used to distribute the Thumper range of portable power packs but no longer have any arrangement with the manufacturer.

Some Thumper models are also designed for high cranking situations.
Thumper

ABR, an advertiser on this site, also has portable power pack solutions and either of these choices will give far more flexibility than the Coolpower IMO.
