Is it possible for me (as the creator) to delete this post?
I'd prefer that you edit your first post. Deleting it would cause this entire thread to be deleted, and I'd rather that the discussion remain.

When you get around to posting a new video, you can update the first post to point to it, as well as add a reply to this thread to let current subscribers know of the update.
 
Well if bleed resistors are used, then it must not have been rebalancing last night because the state of charge would have been lower not higher.
I believe the BMS estimates the SOC based on the lowest set of cells. This is probably the most accurate estimate, because if you run the car to empty before it rebalances, the car will shut down when those lowest voltage cells reach the minimum threshold.
 
Could the cell BMS be triggered on low SOC or a combination of low and high SOC.
The BMS can estimate the battery state better when it sees a larger range of charge states. This is orthogonal to the BMS balancing cells.
