Make sure that you’re also changing the motor power ratings to match the different battery configs. The torque rating changes if you’re bottlenecked by the motor watt limit.
For example if a 10s2p battery can put out 3600w and a 12s2p battery can do 4320, if you have the motor wattage limit set to 3000 (default), then the calculator will reduce the motor current to match the motor wattage, and thus reduce the torque.

when I try to do a motor detection the motors either don’t rotate and it gives me a positive detection or they don’t rotate and it gives me this error. Any advice?
ahh yes. the calc isn’t paying any attention to how many amps your battery can send it to figure out max torque. try changing the p group size it doesn’t affect the torque numbers.
I think it’s computing max torque using the power rating of the motor and the max voltage of the system to figure out a max amps. and from there multiply by amps/nm x n motor x gearing
So that’d be max amps at max speed. II would think low end torque could be higher than that value. like torque/duty_cycle
Jumping in with a new question. Is there a “For dummies” guide for running sensorless on a Unity? I’d really like to eliminate sensor based failure modes from the list of things that can throw me on my ass at speed.
I’m using the Unity app and don’t see any options for sensorless operation. I’m sure it will set itself to sensorless if I run motor detection w/ the sensors unplugged, but I’d like to leave them hooked up for troubleshooting and general data collection.
Are there commands I can enter via the terminal to make this happen? Do I need to use VESC Tool instead of the Unity app?
Usually step 3 fails the first time. I typically have to increase I to 8A and ω to 300 and D to 0.12 to get a successful detection on a large motor (6374)
Any creative ways of covering up holes in the enclosure that I drilled but don’t use anymore? Is there like a cool little aluminum circle emblem that I can put on one of the holes in the center of my enclosure?
@kcheng5
Pretty sure a buttplug fits snuggly in there
But seriously, you could use pretty much anything you want as long as you don’t go for jbweld steel version (it has steel powder in it)
I’d be putting a sweet sticker on the outside and filling the inside of the hole with epoxy
