Lithium batteries and alternator protection.
The six 6 volt lead-acid house batteries in my class A DP have gone bad. I am looking to replace them with 6 Battleborn 100Ah 12v LiFePO batteries. Eventually I will be adding solar. I am not look...

Almost all vehicles for the past 15-20 years or so, use some kind of a smart charging system. The voltage from the alternator is controlled by the engine computer and can vary over a wide range.
Smart charging started in cars but moved to all Ford produced vehicles fairly quickly. The size of the alternator did not matter.
What additional information do you want ? To see it in action, turn just the headlights on for about 5-10 minutes. Hook a multimeter directly to the battery. Start the MH and hold it at a high idle. The initial voltage will be in excess of 14V. It will drop within a few minutes. After about 5-10 minutes of high idle, the voltage will drop down to about 12.6V - 13.2V. This is lower than any conventional alternator/regulator.
