How to make Mini OSD to monitor higher voltage?

Hi All,

As I read the instruction of Mini OSD, it only can monitor 3S voltage. However, there as many guys used 4s-6s lipo on their copter, I am using 4S as well. Could the Mini OSD monitor this voltage?

I thought No.

So, could we modify the hardware to monitor these higher voltage? and how?

jDrone is currently selling these kind of OSD but it is clone one, I would like to use 3DR Mini OSD.
