Battery & Fridge Newbie

[tiger99]

Hi Gurus,

I'm currently researching a simple battery solution to power maximum 40 ltr fridge. Camping is not our thing so just needing something for day runs up the.beach. Get home and throw it on a charger for the next day. Planning on putting it in the seat well. Anyone have a system that works like this? What size battery would be sufficient? What sort of charger would I need? Would I need to charge it every day? Does a battery box fit in the seat well and still allow for the cover to close? Any other advice? Thanks

Pete

Hi Pete, I just did this with a thunder dc-dc charger and a 130ah- check out this link for some cool ideas.Those with Dual Batteries - AGM location?

Additionally have you thought of a thunder weekender or an arkpak? Bulky and probably won't fit in the seat well but would be perfect for your setup.
Cheers

If you are buying a second battery anyway, and a battery box by the sound of things, I can't see why you don't just put in a second battery wired to the car and either in the third seat area or under the hood. You won't need to worry about charging and they are great just for times when you buy meat and aren't going home. Just use the fridge. Also good to keep drinks cold when off to the park or beach. It's not exclusively used for camping, they are much handier than that.

Depending on your budget, you could go for a simple battery box with Ciggy socket

https://www.tentworld.com.au/buy-sale/projecta-battery-box

Or a fancier one with inbuilt charger

http://www.bcf.com.au/Product/Ark-Powerpack-2-Battery-Box

You'd ideally be fitting a 100Ah AGM battery in either of those. Good for a few days.

Or you could go the plug-n-play option of the Waeco. A smaller 44Ah battery but lighter weight.

And the fancy version https://www.tentworld.com.au/primus-...ower-pack-44ah

Kickass also have a range of kits https://www.australiandirect.com.au/...tteries/120403

Wait till supercheap or alike when they have a sale and get a deep cycle battery. . We went with a century 100ah .. buy a cig connection with leads .. and a cheapy battery box (stop spilage) also buy a minimum 10amp charger to top up

Expect 1/2 hrs out of amp hour (ah) rating of battery on fridge / freezer

Gday mate.

I have done this quite cheap.

you can get a 130AH Deep Cycle AGM Battery for $269 here, or maybe cheaper elsewhere. http://www.aussiebatteries.com.au/ba...-cycle-battery

I had one given to me by a mate, second hand, but still good.

I bought a Projecta Battery box http://www.ebay.com.au/itm/PROJECTA-...0AAOSwCi9Z00MQ for $36.

I bought a heap of Anderson Plugs on Ebay for about $1.50 each and fixed 2 of them to the battery box. I dont need cig lighters and stuff, but no reason they couldnt be mounted if you want them.

Ive also just bought a Projecta IDC25 DC-DC Charger for $245, which I will also fix to the top of the Battery Box.

I have a CF40 in the back and its on all the time.

Battery fridge

Hi
If your only using it as described , to state the obvious, you don't need a battery at all.
Just run a cable from the battery to the back of the car and add a new outlet where the fridge is normally . I run a 38l fridge off the car battery and have no problems running for at least 24hrs with out using the car.
I go camping allot and because the car is often used from day to day it is not an issue. I take a jump starter with me which are very cheap to buy as insurance just in case.

Probably the easiest and smartest idea!! Even if you only upgrade your start battery to one with higher amperage (depends on what size is in there now). I know the standard battery that came in my NW didn't have enough reserve to power a penlite!! Cheap and only just did the job...only lasted 18 months as well....so definitely a larger battery required to run accessories like a fridge.

[tiger99]

Thanks for everyone's replies. I like the idea of using the start battery but have concerns about running flat. I replaced the original (18 mths) with a larger RACQ battery which I suspect is a piece of sh!t. I've left the car doors open for half a day and come back to a flat battery, so doubtful it would stand up to a fridge. So my options so far:

1. Run off car battery. will require upgrade to better battery plus purchase of rear cabling/fittings and a portable jump starter. $300 + $80 + $200 =$780

2. Battery box in rear + 110 AGM + cabling/fittings + tie downs + 10 Amp multi-stage charger. $36 + $269 + $80 + $10 + $110 = $505

3. Waeco Raps 44 + multi-stage charger. $300 + $110 = $410

4. Kickass complete portable dual battery kit DC-DC (includes cabling/fittings/battery/240 charger/dc-dc ) $1131

So it's either option 3 or 4. I'm leaning towards the raps 44 as I don't think I'd be driving enough klms between trips to give the battery a good enough charge and will only be doing day trips. Would 44AH be enough to run a WAECO CFX40 as a fridge for a whole day in 32degrees ? Would a 10 AMP charger have it charged up to capacity overnight? Appreciate any further comments & feedback

Thanks,

Pete

Option 1 = $580, or you've left something out

[tiger99]

Sorry $580 option 1

You don't need a separate charger for the RAPS44. We used our 36 for ages with the fridge on it charging it from the rear light socket. Left the RAPS in the car all the time, and put the fridge in as needed, so the battery was always charged
