Goodmorning
I have 2 x 2 victron agm 220 ah in series-parallel for 24 volt 440ah.
My midpoint deviation measured by smart shunt is around 0 to 0,3 % maximum.
This is up to 0,0 to 0,07 Volts difference.
When batteries are charging and in absorption stage the deviation is up to 0,7-0,8%
After charging is finished, deviation slowly goes back to 0 - 0,2
What is an acceptable value for this?
My alarm is setup around 2 percent by deviation (standard)
All is connected by busbars and equal cable lengths.
Setup is protected by battery ballancer.
Batteries are 2 weeks old and setup is as wel.
Can i expert higher or lower values?
Best regards and thanks in advance!
