Can anyone explain why the backup battery went away? I've wasn't on a team in IFI days, but I maintain a robot with an IFI control system. To me, this seems like the best possible solution to the problem.
Also, I feel like if you set CAN low and PWM to zero and turn relays off, you kill all the motors, so unless your battery is literally useless, any other power you can draw(unless something's shorting) will be plenty to keep you above 4.5v. Even if you're using all the servos and sensors you possible can. I feel like it still would be a trivial software(unless its on ROM) change to not make the roborio stop doing 5v and 3.3v rail stuff down to at the very least 5v.
Another quite simple option would be allowing a team to supply a regulator(which fits some sort of inspection standard) to feed the roboRIO.
