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...

mblof, hat you say makes sense for normal batteries. My concern is since LFP batteries have very low internal resistance they may be able to charge/discharge each other faster than what they can handle. Since my batteries only have a max 50 amp charge rate capacity I was concerned that the charged battery would try to charge the discharged battery so fast that it trips the 50 amp BMS limit (or worse - doesn't trip it) and then resets and starts the cycle over. It seems that constant tripping would be bad for the battery being charged (and perhaps the battery doing the charging).
I just don't know if this is a practical concern in the real world.
StirCrazy, I don't have autostart on my generator, this is a 2000 Bigfoot truck camper with an Onan Microlite 2500 propane generator. For some reason it wouldn't start when the batteries were low but starts fine with a fully charged battery. It would carank fine with low batteries but once it fired it would kick the starter motor out and faild to continue running. I gave up on trying to figure out what the problem was and put the 4 way switch in so I could reliably start the generator.
