MM arming on 5s?

[jhautz]

I have one older MM that is slightly sensitive on the overvolt on 5s. It works perfectly if I change my charger setting to charge to 4.15v per cell (20.75v for the pack) rather than 4.2v per cell. If I charge the pack all the way to 21V it doesnt want to start. I need to drain 100mah off the top of the pack and then it works perfectly. The other MMs I have arent bothered by 5s and work perfectly. These are all the older style though.

Try seeing if a not quite completely peaked 5s pack will let tthe MM start up.

I've had no issues on mine after the upgrade. At least no issues that werent there before the upgrade.
