Sorry for the repost. I tried to include a link to my Progressive Dynamics reference and it canned my post. I tried to find it and could not. Black holes are real.

I'd like to swap the two wet cell house batteries for two lithium. Does anyone know if the existing charging equipment: converter/inverter, generator, battery management system and alternator will properly charge the lithium batteries?

Has anyone personally done this and can verify the following:

Question: “My Present RV has a 45-Amp Converter/Charger. Can I Install a Larger 60-Amp or 80-Amp Unit to Further Reduce My Recharge Time?”

Answer: “No, your RV wiring system is designed to safely handle 45-Amps increasing it to a 60 or 80-Amp charger could cause a thermal event! When updating to a Lithium Battery System, stick with the same size Converter/Charger as presently installed in your RV! Again with the faster charge rate that Lithium Batteries can accept even a 45-Amp Lithium Charger can recharge a 100-AH Battery, (100-AH divided by a 45-Amp charge rate) that would equal about 2.2 hours plus the extra time required at the end of the charge due to a lower charge rate, would equal an estimated recharge time of approximately 3 Hrs.” (re: Progressive Dynamics FAQ)
