SQOD Squad - Stupid Question Of the Day (10 Viewers)

[Willy beamin]

picked up a Dometic cfx 75dzw, I have a large family - Anyhow this unit has a selectable 3 stage battery protection system built in - per the manual - There are three set-able battery protection levels; "Hi" equates to 11.8 volts (High cut-out), "Ned" equates to 11.2 volts (Medium cut-out), "Lo" equates to 10.1 volts (Low cut-out). These are the voltages sensed at the refrigerator under load at which the compressor will shut down to protect your vehicle battery. If you have a small battery in a smaller vehicle, you should select high so that you are able to restart your vehicle easily. If you have a larger vehicle and larger battery capacity you should select the medium setting. If you have a dual battery set up and the secondary battery is able to be isolated from the starter battery you should select the Low setting.

My question - Should I be good just running this off my main battery seeing how this is my daily driver? If I was to not drive it for a few days in a row I'd unplug to cooler or plug it into my house. Trying to not go with the extra weight and expense of a dual batt system. I read the manual but was looking for real use perspective from users who run on a single battery

everything hooked to my main battery is:
40" LED Light bar
9" LED Spotties
CB
Rear bumper LED's
Winch
Fridge???? - Am I pushing it? I don't use everything at once anyhow

How many amps does the fridge draw when the compressor is running?

And who is "Ned"?

 

[Willy beamin]

Ned is medium
Mode. New wording i guess ha no specs listed that i coupd find to answer that question. I did find a review on 4xoverlandadventures 14.61 amps consumed over a 24 hour period. When running the fridge draws between 5.0 amps and as low as 3.5 amps. So 4.5-5 on start up but after a few minutes drops well below 4 amps.

I don’t have a Dometic, but it’s setup sounds similar to my National Luna.

My two cents:
-Set it to medium...
-Plug it in to an extension cord in the driveway to ease your battery.

If you set to high protection...at least on mine...it can be too protective and you end up with warm contents.

Medium likely best.
Plug in when you can, and good to go.

I have an ARB 63 qt fridge hooked up to my main battery (no dual batteries here), and it's not a problem. Caveat being I have a group 31 Interstate AGM battery, and I use a fancy Odyssey battery conditioner on it regularly to ensure it's getting a full charge. I also have a circuit breaker in between my battery and fuse box the fridge is wired to, and I flip the breaker to the off position whenever I'm not using the fridge (which means almost always off since it's not my daily driver).

@mcgaskins Im surprised the 16 isnt your DD. Goes to show how great these are when you choose the 12 year old 570 to DD. I get it though, rack up miles on the one that already has a lot.

Are you keeping the Tacoma?

The LX is one of the best daily drivers around, and I honestly love driving it. The AHC is brilliant, and it doesn't hurt that the LX has 115k more miles on it so I feel less bad about piling the miles on The Tacoma is listed on Expo right now, but if I won't mind if it doesn't sell. I got an offer for $2k less than ask and turned it down because I'd rather keep it and enjoy then sell for much under ask. I'll just keep that one and sell one of the 200s instead if it comes to that.

Thanks for this. I had the same question. I put a big 90+ amp hour battery in but still running on “high” voltage cutoff but was wondering if medium was more appropriate.

It also depends on whether you have dual batteries or not. Further, it depends on what your particular battery can handle, especially if a single battery, and how low it can go yet still have the grunt to start your engine. If you have two batteries that are isolated, you just want to make sure that you’re isolated fridge battery doesn’t go so low that it damages its ability to recharge.

Battery issues like these are often difficult to figure out, and frankly I’m still tweaking things too. This is why companies like redarc and others are devising new ways of dealing with battery recharge, etc.

Maybe post a link to the exact units you are after...

Here is the link to Toyota.com.au LandCruiser 200 Accessories & More | Toyota Australia you will need to select the vent shades.

I have a single X2 Power AGM battery. Plan on experimenting this weekend by letting it go to the voltage cutoff on "medium" and if it will still turn off.

As others pointed out, the ARB manual recommends "low" for dual batteries, "high" for starting batteries, but no explanation of what "medium" is for. My hope is that it's for "big ass AGM".

If you decide to go with the low setting as you mentioned from ARB… Make sure that your batteries are operating in isolation from each other. Otherwise, it could run both batteries down and then you’re in trouble. I think the low setting assumes you have isolated batteries. Some people don’t, or… They think they are isolated, but are actually linked depending on their battery management set up. Some battery management systems automatically connect both batteries when one battery is low. That can lead to two dead’s. :-0

if you run a fridge off your main "only" battery, carry a charged jump pack.
I have a knock off Dometic that only has the low setting. it was too low to start the truck. quick bump off the jumper pack and I was back in business.

That said; the only time I have had an issue with the battery and fridge, the battery shifted and one of the caps for the water got knocked off. the battery only had full water in half the cells.

I also ran dedicated power to the rear corner where the jack is stored and added a voltmeter there to monitor battery voltage.

Is there any way to tell what OME coils I have? I bought my 2011 LC already lifted, but have no clue what parts were used. I can't see any stampings or such. Any ideas?

 

[Willy beamin]

Normally theres a white tab / flap of paper with the markings on it OME####

My domestic fridge slide came in today and I'm trying to seek out clean ideas on securing it to the rear cargo tie Down points. I don't have a drawer system so please let me know what's worked for you and pics are always greatly appreciated.

Thinking this will work? Yes or no that's a horrible idea because???

My quest for OEM 2013-2015 LX570 wheels have come up short for our '08 LX570.

I was wondering if can mount the LC 2008 wheel (pictured) and then cover it with an OEM LX570 wheel cap?

Where are the tie points on the fridge itself? End handles? Side? Both?
