It looks like I need to be thinking something like 2500mAh for the power for Nigel v1. The current option I have showing up hits that, but for anything else, I’ll be still be looking at separate battery options or more circuitry. Also, bigger batteries. All told, I need to power the Pi, camera, ir imaging, whatever other sensors, and however many motors. The motors I have lying around have a stall current of 1500mAh at 3v. So that might be an issue with what I’m thinking.
Peter's stuff.
