So I recently pickled up 4 Maytech superfoc 6.8’s from them and incorporated them into a 4wd solution. Got the build finished and all buttoned up so I program the VESC’s for my appropriate specs. Go to test ride it and when it reaches about 5mph (slower in most cases) it completely shuts off. I can cycle the power and it will go again but as soon as it hits around 5 it dies again. It is consistent and happens every time.
First thought is it’s a VESC problem. Let me back up, When I went to first program the VESC’s the firmware was on 3.61 or something like that. The newest is 5.1. After many repeated attempts (all of them ending with the VESC tool telling me that the firmware was successfully updated - it wasn’t) at trying to update I ended the evening with two VESC being updated and the other two not. I kept getting errors mainly with the tool telling me either the firmware was too old and wouldn’t run the wizards, or flat out refuse to connect to the VESC.
Today I used the VESC android app and it seemed to have updated all four VESC successfully (after several firmware read errors). I was even able to run the motors and app wizards on all four VESC’s. Yet I still get this problem with not being able to go over 5mph. The battery is 10s4p and brand spanking new, not even one cycle through it yet (it’s fully charged according to voltmeter).
I’m sure some screenshots would help you guys but which ones do I snapshot? I can’t find one that shows amperage cutoff value.
