I researched what was going on and it appears that it's normal for the cell to bleed down to 3.35v like mine did. Not sure but it's performing normally so that's all I care about. My pack only sags to about 35.8v under 40 amp load and only to about 38v under a 20 amp load and that's very very good.

Check out this pack...it sags all the way from 39v to 32.7v under only a 20 amp load. That's a crappy lifepo4 pack. Not sure who the maker is. Definitely not Thundersky.
