Lithium batteries

[Andypar]

We have a 2020 3901 and I recently replaced the 2 wet cell 12v with 2 100ah Lithium batteries. Replaced the charger in the breaker box as required to properly charge the batteries. No issues until the last week. While at the shop for some warranty issues one of the 12v breakers started popping. They only way they could stop it was to put a wet cell back in it.
Any thoughts?

I just purchased 2 Lithium batteries to replace my 2 wet cell batteries. What charger did you switch to? Do I need to add anything when charging by the pickup alternator?

I also purchased 600 w of Renogy Solar panels to install.

What I found out is the auto reset breakers don't like the 14.5 voltage. I replaced the auto reset with a manual reset breaker and the issue went away. I have 800 watts of solar.
