EB200 battery balance

I took delivery of an EB200 last week and I’m trying to get up to speed. One thing that I found here in these forums was some discussion about battery balance (see image):

My BMS readout shows the cells with a much wider range, 3.52 to 3.38. I’ve taken the unit down to 0% charge and back to 100% twice and this situation has not improved. Is this a cause for concern?


I’m surprised no one had a response. If I’m asking stupid questions, it’s OK to say so.

Regarding the balance post above, the readings were taken right after the power brick charging cycle had completed. Once the system had a load placed on it, the readings equalized both during discharge and at rest, with the latter showing uniform 3.33V on every cell @ 80% charge.
