Default ECU Low Voltage

I have a Rabbit 90 that was updated to a V10 ECU. I was getting a low voltage warning that blocks the start after just a couple of runs. My Battery was an 8 year old 7.4 LiMn, so I thought I'd get a new 9.9V battery. I changed the setting in the Start menu to Life 9.9v.

With my battery charged, reading 10.2V on the screen prior to initiating the start, I still get the low voltage warning.

Could something be drawing down the voltage? Is the 7.4, 9.9V setting only for the Low Voltage warning, or does it affect something else?
