Did you update the MMM firmware? You're supposed to be re-calibrate after updating. I'd try recalibrating and then if that didn't help, try using the manual lipo voltage setting instead of auto lipo setting.
HI!... Yes I'm running the latest software update. V3.29.0 I believe. I've recalibrated it several times. Still nothing.
