I have a customer who has six 6V batteries in series/parallel in a 12v system. The customer's battery spec is showing ±3 mV/°C/cell. He is setting up a 12V Multi in Victron Connect and needs the correct value for his batteries. The default is showing -16.20mV/°C.
I'm using the same math that was presented in https://community.victronenergy.com/questions/28107/temperature-compensation-1.html.
A 6V battery is +/-(3cells x 3mV) = +/- 9mV per battery
So for Six 6V batteries in series/parallel would be 6 X 9mV= - 54mV/°C, correct?
Does it matter whether in series or parallel or is it the total number of batteries?
Thanks for the help!
