New 52 volt advance charger problem

[ebikeer]

I just bought a Luna Charger 52V Advanced 300W and charged to %100. The battery voltage when fully charged came out to 59.3 on my multimeter and 59.6 on the dashboard. Is this normal or is something wrong ?

You get a free volt, but really not sure what the +/- % tolerance is.

Id run it down and charge at 80 or 90%,also borrow another mulitimeterto recheck. I’d not be happy if it really is overcharging.

I wouldn't trust either meter to be all that accurate... if (big if) the battery charged to the nominal 58.8 and your DVM reads 59.3 then the error would only be (59.3 - 58.8) / 58.8 ≈ 0.85% error. Inexpensive DVM's might only be 1-2% accurate...

There may be internal pots you could tweak for optimal performance. There used to be a video showing how but it was deleted.

So it should be 58.9 charger output and it would be nice to have a non-conductive diddle stick.
Possible warranty issue.

Greetings ebikeer. I see you live in Florida. Me too. What part?
Here are a couple of links that were given to me by Luna about new batteries and charging them.
