FAQ: Charging Lithium Batteries With an Alternator

I have two 100ah lithium house batteries in my RV charged by the stock alternator on a 2023 Ford F450 RV chassis with 7.3L gas V8. When I start the engine the house bank lithium batteries draw up to 92amps until the bank is fully charged and seems to stop when the bank reaches about 14.6v. Is this 92amp charge rate going to damage my alternator? One of the other videos you have on this channel says that if you only have two 100ah batteries you don't need to do anything, but then other sites suggest I should be using a BIM or a dc to dc charger. The key is I don't want to end up with a bad alternator out on the road. Suggestions? Thoughts? Thank you!

Can a lithium ion battery be used in a portable generator for starting?

Do you offer a sketch for the DC-DC converter? Are temperature controls required [with DC-DC converter] for the alternator at low RPMs?

Are there any concerns with the alternator overheating at idle using the LiBIM-225, I jave a 15 year old 160 amp alternator
