not being an owner of dual battery system, i'm considering the raps 36 for my waeco cf50. Waeco claim it gives 36amp hrs, which should, depending on conditions, give around 36 hrs use.
My question is, does any own/have any experience with one of these batteries?

Wow......how do u come to the conclusion it will last 36hrs? For the money that these thumper type batteries go for i would be spending the money on putting a dual battery system in. My 55amp battery will run my 70lt Waeco for about 24hrs.

brewman,
the raps 36 is supposed to provide 36 amp hours.
now according to the waeco website, the fridge uses an average 0.75 amps/hr, with a temp. gradient of 30C if i recall correct.
So if we assume they are exaggerating slightly and it uses closer to 1 amp/hr thats 36 hours

the cost is $350. and no install needed.

jondg,
ask anyone with a raps 36 and you will get a vastly different answer, and ask how many people will guarantee you O.75 a/h at an ambient of 30c from their Waeco.

At $350 for a 36a/h battery supply, you would be better to get a 75a/h Optima for a similar price, but double the power.

The moral is: don't believe all the unsubstantiated advertising blurb out there.

Hi there,, I must be up front and say I represent Waeco in both Tassie and Vic for Waeco. I'm a keen 4 x 4 driver and have been using the Raps 36 since Xmas. I also use the CF50, feeding three children 2 adults comfortably for weekend aways. I've had some sensational results from the 36. eg at the recent caravan & camping show we ran a display CF50 for 51 hrs before having to charge her up with a Waeco 6amp auto cut off charger. Temp in Melb was around the 17 to 18 degree mark so the fridge did not have to cycle often it equalled a 0.7 of amp power draw for that running peroiod. Hope this helps and have fun travelling OZ.

Greetings Jon

Battery systems, such as the thumper you are looking at, should not be discharged greater than 50% of capacity.

You will also need a more robust 12 volt lead to properly charge you thumper in car.

Battery FAQ will give you a good insite into batteries.

Regards

Paul

Paul, have you considered adding the FAQ into the Members File Swap area. Battery info is a continuing question and people like me are still confused?

Cheers

Good idea. I await my new computer (old one dead). I need to get my backups restored. I will endeavour to do something before I go away for 3 months starting middle of June. If not after I return.

jondg, i've got a cf80 that runs off a 200amp/hour deep cycle battery charged by a 80 watt solar pane and hooked to a car battery switch when running. this will give me approx 1 week of uninterupted running (sunshine dependant). i suppose it all depends on how long u need the fridge to run for as to which style of energy system u use. good luck
