hailong 48v 10ah batteru

[damocles]

What would be an acceptable discharge rate for a hailong 48v 10ah battery disconnected?...I charged mine and in 4 days it went from 54.6v to 54.0v disconnected. Doesn't sound right...does it?

. 6 voltage drop over a 13s sounds reasonable, but you need to give it at least 2 weeks to know if it can actually hold a charge & stabalize.

Seems typical to me. A fully charged pack never seems to hold 4.2V/cell very long, Always some drain. What matters is when it's at a lower voltage. Then I expect the rate of discharge to be a lot slower. For example, I have batteries sitting around 30% about 3.4V/cell, which is a common shipping and storage value. I want them to stay there for months, and they tend to do that,
