I still don't get it, with Li batteries.
The cost is outrageous.
They don't tolerate the cold. My wet cell deep cycle batteries live behind my front bumper and have worked perfectly down to -15F.
Additional devices must be purchased and added into the charging system. I.E. BMS, DC to DC chargers, etc.
4 100 amp GC batteries cost about $400 and last me 5-6 years. That's less than $100 a year for batteries.
We spend the winter months near Quartzsite on BLM property with 500 watts of solar. generator only runs for microwave and hair dryer.
Yeah, Li batteries charge faster, thus the DC-DC charger to protect the alternator. They weight less but that's not an issue for my coach.
For the additional cost of Li batteries, I wouldn't get any more service.
