Lithium battery upgrade

[Kthompson]

I know this horse has been beat to death many times, but after hours of searching, I never found my answer. I’ve been a lead acid guy for ever. Now that it’s time for new batteries, I want to get rid of my 4 - 6 volt 225 ah flood acid batteries. After all of my research, I found the Vatrer 12 volt 460 ah lithium battery with self heating and its own 250 amp BMS. After getting different answers, I am somewhat sure that the 460 ah lithium battery has more usable power than the 4 225 ah lead acid batteries. Instead of doing a dc to dc charger, and an alternator protecting battery isolator, I’m wanting to do it cheaper and easier. Since I have a 3000 watt inverter that feeds certain 110 volt plugs in my coach, why can’t I just plug in a lithium battery charger to that? I figure that I might need to disconnect the house batteries from the chassis battery/house battery isolator, so the alternator will only be feeding the chassis battery. Does anyone see any problem(s) in doing this?

I bought one of these but have not played with it yet.

I still have the LA house battery that will be changed out for lithium and I think I can use this to control time being charged by the alternator . My other battery bank is lithium and the solar charges that most of the time.
