Best Rv batteries

2oldman, BMS does protect from severe overheating, among other things.
What it doesn't "know" is that cycle life shortens significantly when running 10-99% cycle and/or using it (or even storing) at temps over 85, getting progressively worse all the way to 132.

Heat and cold isn't that big a deal if you plan accordingly during installation. Having a way to see cell temps and voltages is a plus. During the past 3 summers seeing ambient temps up to 90-95 I have not seen a cell temp above 80f, 65-75f cell temps seems to be the norm during summer. These are in a front compartment with no special cooling.
With cycle life claims of 2,000 of actually using the entire stored energy of the battery or 4-7,000 cycles with psoc(only time will tell). If you lost a little life out of them will you actually notice?
If a person can't figure to get out of 132f temps the battery is the least of the problems. ;)

Last thing when advising to use 90-30% or 80-20% or whatever % how about putting that in voltages I'm curious to see what you would actually set your parameters to. We are talking about Lifepo4 cells so it should be easy to figure this.
*If* you have perfectly matched cells.
