Lithium Confusion
I currently store my coach in my garage plugged into 30 amp service. My new coach came with lead acid batteries. The coach has a progressive dynamics PD 4060 charger in a mighty mini power center. ...

I have an Iota charger with an LiFePO4 charge dongle. Here's the charging profile for CALB 180 batteries, from 80% discharge back to fully charged. Note that the battery was 100% charged after 3.5 hours.
The charger stays at 45a and targets ~13.5V. When the battery voltage rises up to 14.7V or so, meaning the cells are charged, it tapers the amps down to zero. Then it floats the battery at 13.5V and, wont charge it again for two weeks. After two weeks it wakes up and charges it back up to 14.7V. Repeat PRN. Near as I can tell, this is the recommended charge profile for LiFePO4 prismatic cells.
