It seems LFPs get their 100AH rating from running at 100 amps for an hour They then derive a 20 hr rating of 100 assuming Peukert is so low it does not count Meanwhile monitors are told to use say Peukert 1.1 ? for LFP instead of say l.3 for FLA
So that means if the rating was done at 100 amps then with at least some Peukert the 5 amp real 20 hr rate would be more than 100
Which might explain what some are seeing with their LFPs doing more than rated
That is on top of the mystery 100 vs 120AH thing that keeps coming up
Whatever, IMO just stay well above the low knee since it is not clear where that is
You can enjoy your LFP without pushing your luck on accidental low shut down
