Question on switching to LiFePO4 batteries.
I'm going to replace my 2 lead acid batteries in my Bigfoot truck camper with two 100ah LiFePO4 batteries. I've previously installed a 4 way battery selector switch to allow me to keep one of my batt...

A followup post and question.
I received the batteries with around 70% charge (13.2 volts). One of my concerns was if the batteries would be able to start my Onan Microlite 2500 generator (there was no surge rating for these batteries). My generator was able to be started with one battery so there should be no problems with two batteries in parallel.
I know LiFePO4 batteries should be stored around a 50% SoC for maximum life, but how important is this from a practical standpoint? I dry camp fewer than 10 times a year. If I were to give the batteries a full charge and disconnect them, top them off before going out, fully charge them when I returned (if they were significantly discharged), disconnect them and leave them that way for my next trip, how much am I really degrading their life? I realize I could boil some water in my microwave to get the charge level down but I wonder if it is really worth it.
