Re: URGENT - No power from backup battery/PWM port voltage
Our battery voltage is currently dropping greatly while running the four drive motors. We will plug the battery in and the OI reports the battery to be at 12.6-12.8 volts. We can go forward and reverse with no problem and not a significant voltage drop. It is when we go to turn and reverse on a carpet pad we use for testing that the voltage begins dropping below 9V and the robot can barely turn. Normally the backup would kick in then, but it isn't. To further this, we know the backup battery isn't turning on because it doesn't activate after we kill the main power.
