If you buy a current manufactured unit it does drop to 13.6V. I am not sure when the change was made but I bought a second one 4-5 months ago from etrailer and it is working fine and drops to 13.6V once the battery is fully charged. Now I have a 14.6V power supply sitting on the shelf....

Check the current capacity of the 100AH and 200AH batteries. If you want to run an inverter you might be better off with 2 vs 1. as they may be ale to supply a higher current.

It looks like it is connected properly. Did you drain down the battery so that the solar would charge it? If the battery is fully charged you won't see any charge current on the monitor

I shut off the fridge overnight and turned it back on in the morning and it had been working perfectly. This is a great time of year to visit Grand Teton NP.

I did not see any ice on the freezer and the fridge walls are warm.

So the fridge is an isotherm 85L, the freezer is a compartment inside the fridge space. The freezer is working fine but the fridge gets warm. Are the walls of the fridge cooled or is the freezer supposed to keep the entire fridge cold? The walls in mine are not cooling at all.

There is nothing worse that getting ready to head out for 3 weeks and finding out that your fridge is not working. It is an 85L Isotherm compressor fridge. It cooled down when I turned on, then it warmed up and the compressor runs constantly. I guess I will have to use my Dometic portable fridge...

Pretty sure I have seen that, is it at the Peterson Automotive Museum?

Check out the Anderson Power Pole SBE80, I am not sure how easy it is to get but it looks like a good fit. https://www.mouser.com/ProductDetail/Anderson-Power-Products/SBE80HDLRED?qs=yoCgdRjoRtGFj7R1M1bczA%3D%3D Louis

The Titan Missile Museum in Green Valley is in interesting couple hour tour.

I bought the Optronics flush mount lights, they have a slight downward tilt and are fully waterproof. Not cheap but should last forever. Optronics 12-L.E.D. Low Profile Exterior Scene Light (UCL41CB)

Did you top balance before your capacity test? I would hope that the cells will deliver their rated capacity. Louis

Thanks for the info, I will start hunting for some good plywood. Louis

I am thinking about converting my Grandby to a NS sleeping arrangement as I am pressed up to the sides while sleeping EW. The existing plywood for the sliding section of the bed is 1/2" plywood, I am trying to find out if that is sufficient or if I should use 3/4". Has anyone made this change or...

Have you already ordered a BMS? I have an extra one you can have if you pay shipping. It is rated at 100A draw and has bluetooth. Link to the BMS: https://batteryhookup.com/products/12v-lifepo4-smart-bms-w-low-temp-cutoff?rfsn=2267412.b1bf25 Louis

I moved from Phoenix to Redmond to get out of the heat, temp today 108, Phoenix, 106......

I have the 50A version installed in my Grandby. The charging function works well, the only issue I have had with it is the Bluetooth adapter for remote control and monitoring. I have a Lithium battery in my camper so I needed the Bluetooth to configure the charging parameters. Once that was done...

Steve, The BMS is normally internal to your battery and is not part of the camper. You would have a battery isolator between the truck and the camper, and possibly a solar controller and a 110v charger. A DC-DC charger would allow you to have better control over the charging, you would want...

I agree that the PD Lithium charger is a waste of money. My solar has been keeping the battery charged. If I was at a location where power was available I might use it for a short time to top off the battery if needed but nothing beyond that.

I installed the Victron 712 in my camper and I find I never use the display, the phone display is much better. You can buy the Victron smart shunt instead and save a few dollars. I purchased a PD Lithium compatible charger and it is not very smart. It is a 14.6V power supply, there is no way to...

When I did the build on my Grandby shell I pulled back the side paneling, it was pretty easy and then I was able to see all of the tubes. I ended up having to have some additional tube welded in to support all of the stuff I added. I have a few pictures in the camper build that I started.
