If you charge a lithium battery directly, there are a couple of issues even if the regulator has lithium settings:
1. Lithium batteries charge so well they look like a dead short, so burning up alternators and belts is a real issue. 2. If the BMS decides to cut the battery off from charging, it will wreck your alternator. The DC-DC charger takes care of lithium-specific charging, limits the total draw on the alternator, and if the BMS kicks off the alternator is still hooked to the start battery. Re 24 volts: You can buy 24 volt batteries or sometimes buy 2 12 volt batteries. Not all batteries can be put in series and not all can be put in parallel, you need to read the descriptions.

I am thinking about this too. I need to replace my Heart Inverter/Charger, so there is that. I have fairly new Balmer Regulators, so I am pretty sure they have a lithium battery setting. Also, I am on 24 Volt, so if it is available would there be an advantage to using 24V instead of putting 12V in series? Bill Coleman Entrada, Erie PA
