@ejohnson01 , i created a document that should help understand the issue that you ran into : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/dev/voxl-esc-tools/doc/regenerative_braking.md and updated the main instructions to warn against using a power supply: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/tree/dev/voxl-esc-tools#hardware-requirements
Please take a look and let me know if you find this information easy to understand and if you have any other questions about this documentation - we will add more details.
