Re: What is the baseline power draw, and how can it be reduced?
If you do a lot of camping without shore power, I recommend that you consider installing the Victron SmartShunt. It measures all power going in/out of your battery, removing the guesswork. I have an older Lion Energy battery with the idiot lights and they aren't really that useful. If your battery is in the tub at the front of the trailer, it would probably be better to get the IP65 (more waterproof) version. The 300A version of either shunt is fine for a T@B.JHornby said:I have the newer fridge that only runs on electric. I don't think I have a shunt. (Not really great at this electricity stuff.) I have a victron app that can see whatever the NuCamp installed Solar Controller puts out, which I mostly use to see how many amps are coming in off solar, but when it comes to figuring out the state of charge of the batteries, I just push some button on the Lion Safari batteries that has some sort of idiot lights on top of them that shows state of charge wherein 5 lights - full charge and 0 lit up would be zero, and there are 5 lights total on each battery. So if you get down to say 1 or 2 lit up on each battery, you are in danger of running out of power. I am attaching a snapshot of the app output after I turned off the electric heat I have running off shore power in my garage right now to dry the cabin out after our last trip. Obviously there is no solar input because the 320S is inside the closed garage.

Re: What is the baseline power draw, and how can it be reduced?
If you have a Victron controller, that monitor is lightyears better than any of the bluetooth "monitors" in the batteries, especially if your Lion batteries are "old" as you say. The way that lithium battery voltages "drop" make any "blinky light" display or even various voltage readings very misleading.
The best investment to make to sort this out would be a Victron shunt. This would simply remove any question about "is 13.2 volts 70 percent of capacity or 30 percent capacity" of my lithium battery.
The shunt will give you much more and better information about exactly where your batteries are.
The next thing we should look at is the setup of your Victron solar controller. If you are not very familiar with the workings and readouts of the Victron devices, we should have a look at them with you and make sure your solar setup is correctly set up for charging a lithium battery. Show us the setup page.

Haven owner's detailed YouTube review
I posted this video with a Facebook link a week or so ago, and the owner over there graciously posted it to YouTube.
A very detailed, hands on review.
https://www.youtube.com/watch?v=05nXWzvtED4&list=WL&index=1Re: Isolating a non lithium compatible WFCO converter when upgrading to lithium
On our build - 2024 400 . We installed 900Ah of lithium batteries and a 3000w Renogy inverter / charger . Since the new 3000w inverter is charging our lithium batteries , we isolated the standard WFCO converter charger to its own breaker on the WFCO breaker panel .
BTW, We had no issues with the stock WFCO charging our lithium batteries . The auto detect feature worked just fine .
Our 3000w inverter / charger is charging our batteries at 75 amps , if we turn on the stock WFCO charger , along with the inverter charger , we can charge up to 130 amps if needed . Also , its good redundancy , that we have the stock WFCO 55 amp charger incase the inverter charger stops working . Usually we leave the stock WFCO charger breaker off , and let the inverter charger do its thing since we can customize the battery charge parameters unlike the stock WFCO charger . So for shore power charging we have either 75amps(inverter charger) , 55amps (stock WFCO) , or both at 130amps . Also have 620w of solar on the roof .
The stock breaker box setup has the converter , 1200w inverter and rear cubbies on the same breaker . We removed the stock 1200w inverter completely when we installed the 3000w inline inverter . The rear cubbies feed , we moved to another breaker in the breaker box . In essence just leaving the converter breaker by itself that we can turn on or off at will . Usually we just leave it off.

Re: Isolating a non lithium compatible WFCO converter when upgrading to lithium
When I'm plugged into shore power I have a switch and shut off the batteries. Camper 12 volts is supplied by the WFCO. The batteries are then charged by a Victron 30A smart charger. When I unplug from shore power the batteries are switched back on.
Re: Cracks on exterior wall of Avia
To fill in this question about what the sidewalls of the trailers are since around mid 2023: the new sides are "NTXT".
I can't find the exact thread, but this is what one of the Admins learned about this last year:
"In late 2023, no specific date, they made the switch from Azdel to
NTXT. They did this at the same time they started laminating their own
walls in house. I know in the past the wall lamination was outsourced.
I was told that NTXT and Azdel are similar products but the NTXT is
less porous and NuCamp feels the glue adheres better to it than Azdel
during lamination. So if you have an Azdel sticker on your trailer that
is what you have. If you have a new trailer built late 2023 or later
with no Azdel Sticker then you will have NTXT. Of course you can always
confirm this with NuCamp by providing them with the build date of your
trailer."
This is a link to the manufacturer.
Re: Snap Pads
We have had snap pads on our 320's stabilizers and trailer jack plate for 5 years now. Works great. Grips asphalt (and the concrete on my incline garage driveway), gives you a wider footprint on grass and sand and minimizes rust on stabilzer foot plates.
Re: Isolating a non lithium compatible WFCO converter when upgrading to lithium
I don't even let the newer "auto detect" WFCO charge my Lithiums.
