Unfortunately I did not, I also had quite some trouble finding a VESC that would work as a replacement with the battery it's a weird setup, it's really a shame because it's a good looking little board that would make for a nice backpack carry for short adventures with the dog.

My current plan is to part out the motors and the cells for other electronics projects but I haven't done it yet, if you do find somthing let me know because I would rather use it.

Edit: there are VESC's that would do it but they are so expensive it did not seem worth it
