Lithium Battery Question

What breakers would be tripping? I took the batteries to NAPA to have them checked and they said they good, 13.5V and 14.4V.
He was referring the auto-breakers in the front storage area. They are lined up like in the image below. I have an arrow pointing to what they look like in our RV. Typically they take about 10-15 seconds to reset.

So, you would just follow the wiring in the front compartment from the pump assembly back towards the battery. It would be heavier gauge wire and should be tied to a breaker that is rated for the pump motors amperage.
Given that you are likely in cold weather, the fluid would be thicker and that would increase the amperage draw on the pump. It is entirely possible that this is causing the breaker to heat up and trip. It then cools off and automatically resets so operation can resume. Your leveling system and the kitchen slide and the dinette slide operate off of the same hydraulic system so the same breaker would be involved. Your bedroom slide operates via electric motors not hydraulic like the others.

As a best practice, I would suggest that you inspect every electrical connection that you can find in the front compartment (and the rest of the coach for that matter) to ensure that all of the connections are tightened securely.
I found numerous loose connections in the front compartment after taking delivery. It is a small investment in time to take a nut driver to the breaker buss and ensure that they are tight.

Also you could check the installation instructions for the hydraulic pump assembly and ensure that the installed breaker meets the specification that they call out. You might find that there is some room to increase the breaker rating, as I believe the instructions call out a x to x breaker rating. Remember, breakers and fusing are designed to protect the wiring.

I've had the same issue in the middle of summer. Think I'll try changing the braker and upgrading the wires to include another battery isolation switch that is dedicated to the hydraulic pump. I've ordered the parts and will let you know if this fixes the problem. Thanks for the support.

In the front compartment there will be a row of auto-reset breakers on a bus bar. They do get weak and many have replaced the 60A with a larger one. The picture attached may or may not match your installation. Follow the wire from the hydraulic pump solenoid to this row.

Well...it is Winter and the sun is low in the sky so not really good time of the year to get solar charging. Add in a few cloudy days, and you'll have dead batteries quickly. Is there any way for you to plug in the RV, even a simple 120v outlet would do the job.

Adding Lithium would allow the RV to have power longer, but without plugging in and in Winter and clouds...again...it will not be enough. In summer, if you have direct access to sun (no trees making shade on panel) then it might keep up.

You current batteries should have no issue bringing in all the slide and the level up jack IF they a fully charged. Just plug in the RV and allow the converter to keep batteries fully charged. Think of the solar as helping batteries stay charged while driving from one RV site to the next.
I am thinking that I will have two Battle Born batteries in a 310RL or is 3 way better, as we dry camp at tractor shows with no power or water?
On a separate question, will a Honda 3000watt generator run two or 3 air conditioners?

It will run one for sure and maybe two. The key is the inrush current of the AC's, so installing "Soft Starts" is a must if you want to run more than one at the same time. It is the starting current that would kick out the gen. I have a 380 MP with three AC's. I have 6000 watts of inverters and 300 AH of batteries. I could run two with no problem. When I started the third it kicked out. I installed the soft start and no issue with it. Mine were pulling around 8 to 900 watts or power each. thx

In addition to what reactancexl said, if you have any type of surge protector, you might need a "grounding plug" to make a the surge protector allow the power through.

Voltage test on the batteries doesn’t confirm their ability to hold a charge. A load test should have been performed at NAPA this would let yo7 know of the conditions of the cells Good, Weak or Bad.

Installed the 80A breaker along with the 4 AWG wires today. I was able to raise all the rear stabilizers without any interruptions Thanks for the assistance.

Morning, not sure of the actual draw, but you could figure it out with a clamp on amp meter.
Below is the fusing requirement from the installation instructions.
Hope it might help.
