Battery charging overvoltage or bad readings?

[Debunker]

I buyed a 52v battery with charger, all labeled 52v, 20ah.

Afer a few hours of charging, lcd on the e-bike show 61v, I disconnected the charger and discharged to 58 as the limit of a 52v should be 58.8v. I knew LCD may be innacurate, but I can't take a reading of the charger while charging without messing with the wires, and if charger or battery is defective, I want to return them.

Charger gives me 64v measured without charging, sometimes it gives me 61v... Battery suposetly have a BMS, reputable builder, should I worry?

Measured with what? Using what method?

So far it sounds like your last thread did; you might want to reference it for suggestions.

My 48v pack show 55.2v fully charged on SW900, should I worry?

Hi lads, I just finished my 2nd charge after dropping to 45.5v the pack, cause tomorrow I plan a large ride, and now the LCD SW900 shows a charge of 55.2v. Suposetly the charging should stop at 54.6. I remember the first time I charge them right away with multiple re-plugging to allow BMS to...

When is the last time you changed the battery in your multimeter?

Multimeter,

Well, that tells us *what* was used, but not how you tested.

Doesnt' matter...the point was for you to look at your original thread for information, testing, suggestions, etc, since it's easily possible the same problems exist in this similar-symptom thread.
