Anyway, almost immediately after reaching a full charge I could ‘twice see’ the current and voltage ‘momentarily cycle’ from zero amps/14.3v to about 5.5a/13.9v (per LinkLite) only to (after each rapid cycling...) quickly return to zero amps/14.3v and holding ...Per previous evaluations, this seems to be a ‘tell-tale’ sign of end-of-charge BMS cell balancing - thereafter (PD charger still in boost mode) both current and voltage continued to hold FIRM at zero amps/14.3v to denote the completion of this balancing act...

The way I understand it with dropin batteries once the batteries reach full voltage (14.x whatever recommended by manufacturer) they need to be held there for a period of time so the cells can balance.
What you're describing it sounds like the cells aren't going through the full balancing period but without being able to see the individual cells or mini packs inside it's just a guess.
