We did not see a 9 V battery pack in our V5 kit. I have one for EDR, but I have two teams without the actual plastice piece the battery goes into. Is there anything we can do to replace the plastic encasing for the battery?
The V5 does not require a 9V battery back up. Take a look at the inspection sheet for V5 robots: https://www.roboticseducation.org/documents/2018/09/vrc-v5-brain-robot-inspection-checklist.pdf
