Hi Chuck
I just replaced my Trojan 6Vs with a couple a 12V Renogy LiFePO4s in parallel. Because the Lithium's need to charge to 14.4 rather than 13.6, I installed a BIM (Battery Isolation Manager) from Battle Born Batteries. to keep from overworking the alternator or overcharging the chassis battery.
Also, you'll need to replace the house battery charger with one specifically for the Lithiums.
It's a lot more expensive, but I don't think I'll ever have to worry about having enough battery ever again.

Subject: [GMCnet] Battery replacement ?
Good day to all. I am researching battery replacements for our 76 Eleganza II. It has a Progressive Dynamics 40 amp converter-charger with charge
wizard. We have a 850 CCA starting battery up front and 2 six volt Trojan golf cart batteries in the rear. My questions concern the rear batteries.
Should I stay with 2) 6 volt Trojans in series or go to 2) 12 volt Trojan golf cart batteries wired parallel? Should I stay with Deep cycle flooded
or go to Deep Cycle Lithium, or Deep Cycle AGM, or Deep Cycle gel? Will my 80 amp alternator and PD 40 with wizard charge the Lithium, AGM, and gel
type batteries correctly? The Trojan Lithium Ion has a state of charge gauge on top and a microprocessor that turns the battery off if a problem is
detected. When problem goes away the integrated controller turns the battery back on. It states the TrojanTrillium is a direct replacement for lead
acid batteries and chargers with AGM and gel settings with I-E profile. ( which I don’t know what is).
Any comments or experiences are welcome. Thanks..
