I have one of those, they are Zener diodes. The actual cost of the diode is about $1.00 😉 *Probably* I would be OK because of connected loads and the start battery, but I am not 100% sure and you could get a nasty spike. My shore power charger does have a lithium setting, but my alternator and solar regulators do not. I am liking the DC-DC charger solution so far. Another benefit is current limiting, from what I have been reading a lithium battery can take a LOT of charge and look like a dead short to an alternator. If you get a 40 amp DC-DC charger, it limits the charge to 40 amps even into a dead battery. Joe

I have to say I thought I knew this stuff and it seems massively confusing with a ton of directly contradictory information. One big issue seems that if the BMS disconnects for any reason, that will do a lot of damage to your alternator and perhaps other equipment too. Add to that my regulator does not have a specific lithium setting, I would need to get into the custom menus and try and make one. What seems to be the best bet is just to connect the alternator to the start battery and use a DC-DC charger to charge the lithium bank. Some of them also take solar input, so that saves me buying a solar controller with lithium settings, which is something else I don’t currently have.
