So I have completed the "rabbit hole" and installed the Victron Multiplus II.
I started with 2 Lion Energy UT1300 batteries and this spring added 2 more, then I had the chance encounter with another owner and ended up with 2 more, total of 6 now. We initially were just going to use a stand alone inverter but after the cost of the "extra" items and not powering the whole rig I decided to go with the Multiplus with all of the added things that it does it just made sense. I used a extra power cord that I had, another story for another time, and cut it in half to go from the front storage to the power distribution panel as well as the Progressive Industries EMS. Power comes in the RV to the EMS then to the inverter then to the power distribution panel. Although the cord is a little heavy it was the "easy button" and worked very well. One issue with the new Multiplus is it is tall almost floor to ceiling in the front bay, I could have moved it up a little more but that thing is heavy and installing the cleat that it hangs on was done by measuring and I was not doing it again. The problem with it being so close to the floor is the bottom cover for the wiring is held on by 2 screws that are install from the bottom, pain in tookus to reinstall but a short screw driver does the trick. I also installed a board to protect the Multiplus from "stuff" that will be stored in front of it. There are 2 battery switches, Blue Sea 600 amp battery switches, one for the inverter and one for the main. A new style Lynx power distribution block, at some time there will be an update for it to show power flow and what the fuses are doing but that is not out yet. I did not realize this was like this until it came there is a circuit board inside it and hopefully an update will be along. I also installed the Cerbo GX and Touch 50 , this will be used to set the incoming power from shore connection so the Multiplus knows what power is available. To install the Touch 50 inside the RV I needed an HDMI and USB extension cables, coming this week, but I did have it all running in the front bay. 4/0 wire was used for all connections, 10 feet of red and black was enough with about a foot of each left over. I did get the VIctron MK3-USB interface to program the Multiplus, you can buy the Multiplus preprogrammed but I chose this route to learn, howson helped me with that and was very patient in teaching, there is still more to learn but it is working.
There is also an Easy Start on the ac which we did a test run and it worked well drawing 120 amps from the battery bank.
I used 1/4" x 1" copper bar to tie the batteries together in pairs then 4/0 wire to connect the pairs and pulled negative and positive off of opposite ends. This is what Lion Energ shows to connect batteries. I used the copper bar as I had some and it saved on crimps and wire, sorry I do not have a picture of that.
Not much to the install, I am not a very good documentarian when it comes to that I just work at the task and get it done with out thinking of taking a lot of pictures.
Here is the finish install.
And the new Lynx Power Distribution with the circuit board
And of course with all of the important "stuff" placed
You can see the 2 different shelves because this was supposed to be just 4 batteries so I had to add another. Not much space left but it works and I did get rid of some stuff that was not needed.
Thanks to all who have done this type of install and posted here it helped a lot. If there are any questions please ask.
