I have a BMV 700 hooked up to a 160ah battery that is charged by a 200W Solar Panel. Everything works ok. The only problem I have is that the percentage dose not work.
The Display shows 100% at everything higher than arround 13.5. That's okay. But when I drain my battery down to 10v it still shows like 50%. When it reaches 9.5v the system shuts of and the last known percentage is like 45%. How can I set the 0% Mark?
I have a RaspPi connected and can check the values constantly.
