Same circuit in different configuration.

4 batteries 12 V 7 ah SLA used extensive to power this circuit only wired 2 parallel 2 series gives 24 V 14 ah. After few weeks of exclusive usage with this configuration have a resting voltage of 13.10 V old pack and respective 13.30 V after 6-7 hours resting after charging. Many of you will say they experience surface charging … I want to remind you that surface charging will not sustain the voltage under load ! They are used daily for continuous 1-2 hours and they are drawn to 80-60%, occasionally they were used 2 times for continuous 6 hours with approx 100 W load. Manufacturer specification indicate C20 which means in this case 0.750 amps continuous drawn. Circuit used with 100w load draw about 2 amps as seen in videos and even exceeding to 4.4 amps for periods of 30 minutes … yet, batteries are healthy and improving their capabilities by the day.

Circuit is not shielded and no HF suppression is used ! HF is present on every point in this circuit and surrounding proximity, so, batteries will never get the opportunity to sulfate and clog their electrodes.
Also, in videos is shown self adjusting oscillation frequency and behaviour under load with restricted input (high resistance/impedance source or, sources with very little current availability) and with less restricted input (governed by internal resistance of batteries)

More tests will be shown soon on the channel with open circuit on AC output rectified for easy and more precise measurements, different types of usage, methods of scaling up and quantified input/output along with free existing electric power available. Once capabilities of circuit are known we can design adequate methods of capture of free exiting potential for desired output.
