Default Battery Overvoltage


I have taken my VT90 out of storage after more than a year. Lubed it, set it up and attempted a bench run.
I am using the A123 LiFe battery provided by Jet Central, same one I was using prior to storage.

During startup I kept getting battery overvoltage, which was odd because on the ECU Pb=9.9-10V. The battery seemed fine. I discharged the battery for an hour, and the ECU was reading Pb=9.8V and it would not fire up. Same overvoltage message.

So I tried a 7.4V Lipo from another engine and it worked good. Engine ran fine.

Is there an adjustable ECU battery voltage parameter I can adjust or is there something else hosed up?
