I watched your video all the way through.  What you are describing is basically the Three Battery Generating System that has been discussed and worked with thoroughly on the Energetic Forum.  I have worked on that system for about 5 years now so I feel I am pretty clear on what it can and can't do.

You have a couple of mistakes in your video.  The diode is not needed as the battery on the recharging side can never get charged high enough to try and recharge the charging batteries.  You also do not gain anything by adding more batteries in parallel on the recharging side.  This is simply not true.  When you add more batteries the total energy gets divided between them so they don't all charge as much as a single battery would.  There is no overunity just by adding more batteries to the recharging side.  You are correct you can run a load for much longer by recycling the energy back and forth between the batteries but they will eventually run down without some other means of charging them.

If you want to make the system much more efficient you have make use of the spinning motor and a very good generator.  You also need an automated battery swapping system.  If you go to the Energetic Forum and look for the thread called Basic Free Energy Device you will find a lot of information about this system.  I did post there information and pictures for an automated battery swapping circuit.  We are still working on the best type of generator to use with this system.

Ive fiddles with such many years, but im no expert, and always found such interesting. One design Ill mention that I found seemed to work better then the rest was what I called a pulse motor, by simply taking a motor apart, I used a cd motor, not the easiest thing to get apart as most know. anyway took it apart and pulled the motor with winding on it out. Then on the shaft of that at the base there are three contacts below the coils. Im not talking about the two contacts where your power wires go to. Anyway if you carefully bent one of these three contacts back and forth it will fall off, dont break your coil wires. And then put it all back together. and what this produces is a motor that makes contact and then breaks contact as it spins, sometimes to start it you must do it manually by hand. Anyway this will add a great amount of energy back into your wiring for recharging your batteries. Perhaps its because of back emf generated then, who knows. But since I did not mention this in the video, for those interested there it is. As to the diode, without a pulse motor the diode is needed. But opinions will always vary.........

Would it be possible to set up this kind of arrangement using a discharging cap instead of the motor?

we need to cut one wire in the motor and get the collapsing field and charge.
