    2 identical new batteries. do a charge, and discharge cycle at c20 a few times to see what true capacity is. do this with a standard charger and a fixed load like a DC lightbulb, or better yet a west mountain radio CBA 4. this unit wil give you graphs and is a great tool, not very expensive either. then use one battery as your primary and use its discharge current into your machine as the baseline for joules into and out of the machine. fully charge your primary battery before each run. discharge your secondary battery to the same voltage every time with a load that will discharge the battery at C20. discharge to 80% depth of discharge. standard cop protocol.

        We made a double N-S-N rotor test stand for testing generator coils. Each rotor has 16 magnets on it and are 23" dia. From a Youtube video we realized U-cores are not necessary. We have 2 coils back to back inline on a common welding rod core. They are wound identical to our motor coil for now. Other winding patterns will be tested. For now we are running the double rotor with a conventional motor so we can see what affect speed has on the output. On our first test we were at 643 RPM max. As it speeds up and slows down the voltage gradually changes. We will get a speed control to make a speed vs voltage graph. We need to verify our first test - voltage and amps output results from last night before posting them here as they are "quite favorable".
