Built this summer 14s5p, maybe has had 20x+ cycles and worked flawlessly. Last 3 charges stopped at 55.5-56V.

That's the charger and 40A bms. On charger able to change power output (2A-12A) but not final charge voltage like on luna chargers.
All 14 blocks appear to be balanced (3.99V+/-) and the welds are solid. Tried another plastic 4A charger, same result.
What could be causing this behavior?
Is there anything I can do short of replacing the bms and seeing if that'll fix the issue?
Thanks
