Just curious - why Lithiums are so heavy?
100 AH, flooded, 66-69 lbs. 100 AH, Li, 29-31 lbs. Brain-dead sellers jumping on a new bandwagon, "One-fifth the weight of a traditional battery", yahooo.... More usable capacity, yes, but not...

Electric car battery works in different conditions, it has (I think) liquid cooling system that drop-in batts don't.
I'm not sure it really goes down to 5%, what you see on display is not necessarily it, they might show you only % of a "usable charge", but I don't have electric car. Common recommendation for drop-in 12V Li, and 24-36-48 batts of scooters, ebikes etc is running it in 20%-90% SOC.Are the RV lithium ion batts ok with standard RV converters?
It needs slightly higher bulk voltage, and Float voltage is zero - charging must stop when full. But let's not deviate.
So... Anybody saw 20 lbs Gr31? ;)
I think I remember reading that. When my car turtles (is completely dead) its not actually dead. The BMS controls that I believe. I have never turtled either car so don't actually know what happens.
