VESC tool and sk8-esc V6 set up shows incorrectcurrent usage

Hey,

I'm using sk8-esc V6 with  MTO5065-HA-C motor. Im powering this system from lab bench power supply, because I'm intent to use this system for automatization purposes. My lab bench power supply shows maximum of 5 A current when trying to block motor, but the VESC tool software real time monitoring shows current to peak around 10-15 A. So a scaled measurements, also RPMs are way higher then they should be. I get around 700 RPM with a digital tachometer, while VESC tool shows around 10 000 RPM ! Is this normal? Should i get scaled units and how to unscale

them if so? And if this is not scaling problems, how could i fix this? I also set my max current usage to 5A in a motor set up wizard.

Thanks.

I'm having the same issue (I think) with a flipsky 75100FOC on my ebike. The BMS on my battery is only 30A, but in the realtime data it shows the ESC pulling about 50-60A, which as I understand it the BMS would never allow. Is this an issue with the scaling in the vesc-tool software, or an I misunderstanding the way a BMS controls current, or what?

The 75100foc is running like 5.3 firmware, I would like to update it because maybe that's the issue? But I'm afraid to because it's the only controller I have right now and I need my bike to work. Has anyone successfully updated one of these?
