FWIW, at one point I was charging my 36v ping with a lifepo4 charger at home and a lead charger at work.
Lead charger put out 42v, and the lifepo4 charger 46. As an experiment, I fully charged the pack with 42v. 3.5v. Plugging in the 46v charger, 3.8v, the charger would run for about 90 seconds or less. So that told me not much watthours above 3.5v for sure.
I don't have data for a 3.4v charge, but I bet its not a huge amount of wh above it. My pings have always dropped to 3.3v fairly quick when riding, then ran in that area for much of the ride.
But in any case, for the bms to balance the battery, you gotta go higher than 3.4v in most cases. Most bms won't start balancing till they reach 3.65v if not more.
If you got great cells, it may be balanced and nearly fully charged at 3.4v. But if that is the case, likely you are riding happily. Not looking up how to fix your batttery here.
