Re: 2023 400 with the 400 ah Lithium mod. Victron Inverter.
What an awesome setup. I just came across those same batteries while doing my research into the upgrade so I’m glad to see someone with experience. I have a 2023 tab and am most likely going to move forward in the coming weeks. I have a couple questions.B0atguy said:Wow, its been a year already since the last post here .
There are some new Lifepo4 / Lithium batteries on the market now and prices have dropped considerably on them as well over the past year . All that kind of gave me the push to upgrade to more than 400ah Lifepo4 Renogy batteries I have now . They have performed great , just want some more AH !
They are now making some Lifepo4 300ah "mini" batteries that are extremely compact in relation to the AH they are producing . After a bit of research , finally bit the bullet on 3 - 300 AH "mini" battery for our 400 . 3 of them are about a perfect fit in the 400 battery bay, with all that is needed is to remove the center wood divider . Still keeps our under bed drawer intact as well . I did have to "hack" off one side of the battery handles to get them to fit, but all in all it worked out pretty good . Out of the many brands of these (all Chinese , and all the same basically ) , I went with the Dumfume brand . Will Prowse (and others) have given pretty good reviews and tear downs , so I went all in . Now I am up to 900AH , and all 3 fit perfectly in the stock (2024) 400 battery bay . Cant beat the price . They are approx $1 . per AH (as of 8/2025). So , right around $900. for 900 AH . So far so good . Charged up great , and are working perfect so far . Also using a Renogy 300 bluetooth shunt to go with our Renogy One Core monitor panel . Works great for keeping tabs on battery usage !
Here are a few pictures of the install .
1. Renogy specific, can you set an AC input limit like the Victrons? For example could I make it so the inverter only pulls 1000 watts from shore power and supplies the rest of the needed energy from the batteries?
2. More general and probably kind of dumb, but is any extra wiring needed to allow the inverter to power the rest of the trailer including the AC? I know the inverter I have now that came with it only powers a couple outlets so will any extra wiring be needed?
Thanks in advance!

On a side note: We did 4 days of dry camping this week in 85 degree heat, we were able to run the AC from 9pm to 8am and it used about 30% of our 920AH, We were able to charge during the day at close to 900w. It did require that I play solar tracker a few times during the day.

Thanks , I will read this info over but prefer the simple method best . 👍🏻

There was more to the antenna story. Question: are Staples or Office Depot paper clips better for TV reception?

Re: Norcold 3163 3-Way Fridge -- cannot source replacement part
Well I did write "made to work" for a reason, if it was a direct replacement it wouldn't be a problem in the first place. You'd have to modify the mounting tab or create a new one. The orifice is in the threaded part so possibly this can be moved over. But do have a close look if there is a size difference between the orifices, the 3163 is somewhat unique in that it uses an adjustable flame size. The typical RV fridges run full blast with a thermostat turning the burner on and off.
Re: Very low hot water pressure solved
Big thanks for posting this. Upon de-winterizing this Spring, my hot water was down to a trickle. After finding your post, I removed mixing valve, and looked at the valve's input screens. The hot water screen was packed with black plastic flakes. Never would have figured this out on my own. Have replacement brass check valve ($11) on the way. Ready for the season.
Re: battle born battery
I worked for a business jet manufacturer in Wichita and what BB is doing is absolutely stupid. You don’t have to be an engineer to know how to make the PROPER connections when high dc amperage is involved. I bought a “22 Tab 320 and wanted to upgrade the factory battery to the 200ah lithium system. I looked at the BB but went with Renogy due the the cost. I don’t know when the BB issue started but BB but they need to wake up and clean house in their engineering staff. Some decision maker doesn’t know what he’s doing.
if you put ANY kind of washer between the battery terminal and the connecting cable, you’ve introduced resistance and resistance produces heat. The more amperage, the more heat.
