SBMS battery level misreading

[alex sfakianos]

After drawing batteries on my pack down to about 35%, I ran the generator (60A) for a couple of hours. I turned it off when the SBMS showed 70%. Later that day after just a couple of hours of sun I was surprised to see it at 99%. It also displayed occasional  seemingly random readings of  up to 1300A draw. The next morning it showed battery charge level at 0%, even though I had minimal overnight power use. There was no low voltage lock

I saved the parameters and reset the device but that did not change the displayed battery level. After a partly cloudy day it has gone up a few percent. I have looked at the various informational pages and for example the bar graph shows the cells at around 70%. 

I did take fotos of the various screens but have no way to transfer from the phone except for email.

Alex,

Based on the random 1300A readings my best guess is that the current shunt sense wires are broken (intermitent) or you have a bad connection either at the shunt side (the two small sense wires) or at the SBMS connector you have one of the wires with bad connection.

It is the ADC1n wire specifically that has a bad connection problem thus the false 1300A load.
