Bedini/Adams pulse motor running off one battery while charging another (time lapse)

This is my version of an Adams motor with a flyback diode added to capture the spikes in a second battery (AKA Bedini setup).

This two battery setup is the most common, but I hadn't seen any videos that showed the BEMF spikes charging the second battery over a longer duration, so I threw this video together.

There are far more efficient pulse charging systems out there but I think this is enough to give an idea of how these things are supposed to work and that it is possible for the charging of the second battery to exceed the discharging of the run battery:

- Before the motor is started, the resting voltages are 13.00 on the run battery and 11.77 on the charging battery.

- Once the motor is started, the run battery voltage drops to 12.87 because it is under load and the charge battery jumps up to 12.35 because it is under charge. So far so good.

- By the end of the cycle the run battery has dropped to 12.69 and the charge battery has charged up to 12.55.

- The motor is powered off and the run battery voltage bounces back up to 12.75, while the charge battery drops to 12.50.

- If we subtract the ending voltage from the starting voltage, we have a loss of 0.25 volts on the run battery (13.00 - 12.75 = 0.25). We also have a gain of 0.73 volts on the charge battery (12.50 - 11.77 = 0.73).

So we lost 0.25 volts but we gained 0.73 volts, giving us an overall gain of 0.48 volts (0.73 - 0.25). all the while doing mechanical work and lighting the LEDS!
