I have a friend which have a Trampa vesc 6 (the none + version) The problem is, that after newer firmware updates, his vesc is not reading the voltage and used mAh correct anymore. This is pretty annoying… Any way to calibrate these values in the vesc-tool ??
Probably he didn’t hook up the remote and NRF dongle to the same VESC, or PPM remote is attached to the slave VESC.
In that case you need to ad the battery values also to the slave VESC.
PPM or any other input should be attached to the VESC you connect to during configuration.
The additional values like battery capacity and cell number are not written onto both VESCs.
1V / 12 Cells is 0.08V per cell. That is acceptable.
The Shunts are ±1% precise, so there is always a tolerance in every VESC.
One shunt could have a plus tolerance, the other two minus tolerance…
