[HELP] Lifepo4 parameters on inverter with AC charging option (UPS mode)

How to factor in my charging voltage of only 13.6v and my lvd of 11.0v?

Actually i am planning to do a capacity test with bms. I will let the bms hand lvd.
Then capacity test each cell with 2.5v lvd.
Then capacity test with bms but i will set lvd at 11v.

I will post the results here.

BTW my sinopoly were bought used @ 110 usd (for the 4cells).
Data sheet indicate these were actually 100AH.
But sellers sell these and mark them as 90AH.

But i got bloated ones.

With used bloated cells you need to test.
