Hi,
I am in the middle of my first project and I am having an issue with my cells not reaching 3.65v when charging.
When cell 2 reaches 3.65v, the BMS shuts down, but cell 7 is 3.55v.
Also after charging the cells quickly discharge to ~3.37v without anything connected, is that normal?
From my reading, this seems like a top balance issue. Is that right?
The cells are welded together, am I still able to successfully top balance them?
Here is a quick video showing the issue.
I'm having this issue with two different batteries, and two different BMS's.
Any help is greatly appreciated.
Here is the battery that I'm using, Signature Solar 25.6v 8s 100ah pack.
Here is the BMS that I'm using, JBD 8s 100a.
I'm also using the 24v, 40a EG4 charger from Signature Solar, which appears to no longer be on their website.
Attached are screenshots of the BMS settings.
