See the screenshot there, Cells 20 and 21 keep bouncing back and forth between unusually high and low values. Unsure of the cause. Not documentation found to support this behavior. Screenshot 2019-09-20 16 31 13

If anyone else sees this, I found out what it probably is.

It's what happens when there is a bad connection to a cell, it senses a common mode voltage of two cells split between the two readings... ((4.87 + 2.57)/2) = 3.72

Alot of issues happen due to faulty wiring it is a pain to track down.
