The X1 Pro has a built in battery meter that will tell you individual cell voltages as well as the high, low, and total voltage. Delta Peak has to be changed inside of the battery memory menu and saved into a battery profile, it doesn't actually have a separate menu in System Settings to change the default for the global settings.

I like my X1 Pro (I have 2), it's compact and powerful enough for most of my charging needs.

Hey Xpress;
I'm old school. I mostly run 6-cell Ni-MH batteries. I like to see the non-charging voltage.

But; I just plug-in my MRC 977 Pro charger to the 17-amp ePowerbox to view the battery non-charging voltage.

Thanks
