04. Hardware modifications for 30 volt input

Magnus edited this page Sep 1, 2021 · 2 revisions

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;
