Clean install. In the planning stages of adding solar/lithium and it's nice to know that 900ah can fit in the battery box.

I remember watching this video a few years back but forgot about them calling out the terminal design. And is it me, or is the bolt on the Battleborn battery that he says is too small and the equivalent of a 6 awg cable look to be the same size used on the Lithionics battery main connections?

After taking a look at their financials, I wouldn't put much hope into that. And just today they had to do a 1 for 10 reverse stock split to get their share price over $1 to maintain their Nasdaq listing. Down 99.7 percent over the past 3 years.

Yeah, I was too in the beginning, but now support isn't returning my calls or emails. I'll give them a few more days to respond and then I'm going to send it back. Can't blame them if they can't get it to work with my AC unit, but at least respond and let me know...

Down from a high of $258.74 in Dec 2022. Ouch!

All things being equal, on the battery closest to the load. Though all things are never equal!

On all my trailers I cut the ground wire and bolt it to the frame not far from the hitch. Makes it easy to test and repair when brake and/or lights issues arise.

I think they continue to call this obviously bad design a "feature" but in the near future start producing batteries with an "new and improved" way of protecting them from thermal runaway. I also think they stop blaming customers who have batteries that fail at the terminals and just replace batteries still under warranty with no questions asked. If not, I don't see how they'd be able to prove that the terminal damage was caused by "misuse" or from just expansion/contraction due to the use of three different metals and a piece of plastic in their design if a class action suit is ever initiated. I think this is the only way they can continue as an entity and save some of the reputation they've built over the years. I also think they'll have to come WAY down on the price going forward to entice people to buy them again after all this bad publicity.

It will be interesting to see if your temp sensor is as far off as mine was. I've had the unit shut off at 70-71 cabin temp because the internal thermistor was reading 64 which is as low as the unit allows you to set it. Usually don't need to go much lower than that anyway, but sometimes I do just to remove excess humidity. To fix this I added a resistor in parallel to the thermistor to trick it into reading a hair lower than actual cabin temp and seems to be working great now. Need it to warm up some and get the Breez Max working to finish testing and adjusting before giving a final opinion on this unit.

Turbro actually is in the Cielo database on their website. Only one remote though and it's the wrong one. You can see the difference in my post a few posts back.

Well, spent about an hour on the phone with tech support and they weren't able to get any of their remote settings to work with my Turbro. They ended up having me send them each remote command through the WIFI connected Breez Max and now will use that info to try and program a new template for the Turbro. They said they should have it done by Tues. Pretty strange since @Treasure Coast Vaultdidn't seem to have any trouble setting his Breez Max up with the seemingly identical Pioneer unit. Told tech support this info and it didn't seem to help any... Maybe not so identical after all? Why didn't I let @jd1923try setting his up first?

I did find the "Turbro" brand on the website, but as you can see in the pic the only remote they show is much different than the one I have (mine on the right). Sent them all the info they requested and just waiting for them to get back to me.

Ah, maybe I read it wrong and Turbro isn't in the database at all? Waiting to hear back, but will bring up the fact that the Pioneer Inverter units look to be identical and see if they can recommend which remote model to use for my Turbro. There's a bunch of Pioneer models in there...

Might want to wait on that. Installed my Breez Max today and couldn't get it to work correctly using the auto detect for the remote, nor by trying to manually enter the Turbro info. It's shows the Turbro brand in the manual setup, but only one model remote and it isn't the one I have. Got it to to turn the Turbro on but it would turn the built in LED's on and off when it was trying to change the temp. Going to contact support in the am and I'll let you know how it goes.

I'm no Electromechanical engineer, but there has to be a better way to protect a battery from thermal runaway. How are others doing it? It also seems as though their design doesn't work as intended (at least for the battery in the video).

Thanks, I did a little reading and fully understand how the transfer switches on Ollies work now. My only expedience with a transfer switch was on a boat that my father owned. It had a transfer switch that switched between onboard invertor power and shore power and I'm almost certain that setup needed battery power for it to work correctly.

I would still check the battery voltage. If it's too low it might be causing the issue with the relay. Seems weird that you had battery problems and then the relay decides to give up at the same time.

I don't have an auto transfer switch on mine, but I don't think it will work without 12v going to it. Maybe your batteries are completely dead? Maybe use jumper cables from your TV to get enough juice to get it to work? I'm sure other will jump in who are more knowledgeable on this. Good luck!

I love your math and will be using it as my sales pitch for new Nev-R-Lube axles to my wife. She'll then return the favor by letting me know what she'll be spending that saved money on!

I find it works fairly well if you keep the phone close to the internal antenna mounted in the cabin. Usually adds 2, sometimes 3 bars for us. .

Oh, I have no doubt it will work with my Turbro, I just don't think it will have the ability to override functions programed into the control board of the unit itself.

In a perfect world, it would work just as you describe. With the Turbro/Pioneer inverter units, at least, this doesn't seem to be the case. Yes, the compressor does ramp up and down as needed but the internal supply fan works no differently than standard compressor units do. The fan has low/med/hi settings and is not a variable speed ECM motor like residential mini-splits have. Probably a money saving move and feature they thought people wouldn't miss in an RV. I sure miss it... especially in heat mode where the fan locks on high speed and doesn't allow any adjustment. Looking forward to testing with a Cielo thermostat soon to see if it can override this feature but my hopes are not high...

They also replaced the plywood subfloor with a composite, which is a big plus.

Section 551.71(F) of the NEC is specific to RV parks only so not applicable to your situation. And as @Snackchaser stated, wiring to only one side of a double breaker is fine per the NEC. Might not be needed though if your local AHJ hasn't adopted the new code yet.

I thought I read something a while back that the new code requires GFCI protection in a residential setting but RV parks were exempt. Don't have a new code book but will see what I can find. Edit: looks like the updated NEC 2023 code 210.8(A) does include any 125 through 250 volt outlets installed in a garage or accessory building be GFCI protected. The code covering RV parks was not updated so only pedestal outlets 20 amp and under are still required to be GFCI protected. Contact your local construction services dept to see if they've even adopted the new code or not, and if they have, I would just install a 30 amp single pole GFCI breaker for that outlet.
