[0024] 2) The active balancing circuit 1, DC conversion controller 2, current controller 3, magnetic capacitor battery power module 4, LEDS5, flash / flashlight / off switch 6 and battery 17 together constitute a basic flash circuit (LED) with a magnetic capacitor battery as the main power source, which supports flashlight or continuous lighting, and the mode is suitable for video capture; this circuit uses a magnetic capacitor battery module as the main power source, and realizes the flashing or always-on working state of the flash light emitting diode through the flash / flashlight / off switch 6, active balancing circuit 1, DC conversion controller 2, and current controller 3; the magnetic capacitor battery power module 4 realizes the overall weight reduction and power improvement of the system.

[0025] For further information, please refer to Figure 2 , Figure 2 The magnetic capacitor battery power module of the present invention is a structural diagram.

Its capacitance is 1.0E6-1.0E17 times greater than the capacitance of standard capacitors and dielectric materials of the same size.

By keeping the weight of the energy storage element low while maintaining the required energy storage capacity, the energy storage container weighs very little and can be easily installed on existing structures. Because it is removable, users can easily swap out fully charged modules.
