A neighbor ran his 16S LiFePO4 EVE 280 battery bank down to zero while he was gone for an extended period. I am trying to see if it can be brought back to life. I have charged up some of the cells and then tested capacity, and measuring 250-280AH on various cells.
Based on a single test it appears the cells retain significant capacity, although I have no idea of what type of cycle life they will have moving forward (they are 2 years old).
Curious to hear from others that have attempted to revive LiFePO4 batteries that have been totally discharged and what happened when put back into use?
