First - Sorry
I know it has been asked before, but I can’t seem to find a solution to the earlier posts from other users. So, therefore, I allowed myself to ask.
Setup: My battery is a DIY (Winston 200AHA) project, a 12V system. 8cells in total. Two parallel and series.
From the last cell, the negative terminal is connected to the shunt for the BMV-702 (on the battery side of the shunt), from the load side of the shunt there is a 100A copper bar connected with all the negative connections to loads.
So that must be correct.
Problem: The BMV-702 won’t do the regular automatic synchronization.
Settings of the BMV-702:
02. 13.90V (.30 under the absorptions as recommended)
I know that 03 and 04 normally are 4% and 3 minutes, it didn’t work, so I tried to make them smaller.
Have tried to sync when the battery is fully charged manually, it hasn’t helped.
Here are some screenshots from the settings:
