toddb: I'm about $850 for 250a/h of AGM Lifeline 31XT batteries. Where are you pricing the $950 lithium and what are the a/h and size? I'm also curious on yours and others thoughts on the fire risk. I realize there are different chemistries. I believe it was the Airbus A380 that has fires early on due to lithium battery issues and Texas Motor Speedway recently banned all electric vehicles from drag racing due to fire risk and not having proper fire gear to deal with it. https://www.thedrive.com/news/29192/tesla-cars-and-other-evs-banned-from-texas-drag-strip-due-to-battery-fires
I will study the Victron Energy website.
The biggest problem I see for lithium batteries is that are killed if they freeze. Do they freeze at 32 degrees like a conventional battery? We often use the camper throughout the winter as we are TX based. Driving through 15-20 degree weather seems like it would potentially freeze & kill them. In storage at the house we can see several days in a row with lows in the low 20s. It is likely I will forget to take them out or be traveling when a front comes through and won't be able to remove them. That's a huge plus for solar on the roof is that I will not kill batteries when not in use as they always get charged.
