    So if you have a 60a converter like me, with 4 lithium batteries; they are only getting 15a each.

    That's not a lot, but way faster then a converter into a wet cell battery. 15a in till it's done, per hour. KEN

    I have 2 Battleborns and the 9160ALV convertor. The one time that I drained my batteries down the OEM wiring got pretty warm until they got charged back up so be careful with a larger convertor.
    I also had an issue with the OEM resettable breaker tripping. I going to change it because its not big enough for a large amp draw that occurs when batteries are drained low.

    Yes, 50A per 100AH battery. So if you have 4 - 100AH batteries you can use a 200A charger.

    There's a lot more information needed to understand why you have that issue.
    Wires get warm normally, that's why they have a temperature rating. A normal 90℃ (194 ℉) rated wire would feel way too hot to touch, yet be totally safe.
    Breakers trip both on over current and/or temperature for many reasons... loose connections, over current, corrosion, faulty breaker.
    Check all of those things first, but NEVER put in a larger breaker than the wire is rated for.
    Believe me, it well worth the aggravation to reset the breaker than have your RV burn down.

    Just FYI, If you go that way, be sure you can actually get one. WFCO told me a few days ago all the 75s were back ordered 'til mid May sometime. (I was looking for a stand-alone so if yours is integrated into the panel, those might be available, but...?)

    Have you considered doing a dedicated 20A receptacle that goes directly to the charger? Every shore power post I have seen has either a 50amp or 30amp hookup as well as a 20amp standard outlet. Same goes for every generator. This would remove most of your concerns except possibly the gauge of wire from the charger to the battery bank.

    Battle Born says a 100 amp battery should not be charged at over 50 amps. Not sure about other brands.
