04. Hardware modifications for 30 volt input

This description guide you how to rebuild your RazorBoard to support input of 30 volt (max standard is 25.2V). Typically this is needed when you use 7-cell Li-Ion battery pack that's need a 29.4 volt to fully charge.

NOTE - This is by you own risk!!

Replace R4 and R5 with a 5.6kohm resistor (SMD 0603), this gives a input voltage of 4.625 on 29.4 volt input

You need also to update the software by the setting for the correct calculation of the input voltage

settings.voltageMultiply = 6.356;
