You can power a powerful DC motor not only from a conventional battery, but also from a homemade supercapacitor battery. A large selection of such 2.7 V supercapacitors is on sale.When they are connected in series using a balancing board, you can get an almost full-fledged battery. It is capable of supplying weak 12V consumers for a long time, and also, due to the rapid return of the charge, it starts the car starter. You can assemble such a device from purchased components at home. This will be a great homemade product for a home laboratory.
Supercapacitor Battery Manufacturing Process
To assemble a storage battery on supercapacitors, in addition to the latter, it is necessary to purchase a single-row balancing board for 6 supercapacitors. All of this is sold on Aliexpress. Due to the difference in resistance, series-connected supercapacitors charge at different rates. Without this board, on one of them, while charging, the voltage can exceed the permissible limit, when the others have not yet reached the required 2.7 V. The balancing circuit of the finished board prevents this.
Capacitors must be soldered into the board observing the polarity according to the marking on it.
Then the power terminals are screwed onto its extreme contacts.
Such a device is charged very quickly with a 3A power supply. The result is a compact and lightweight battery.
It allows you to power any consumers almost like a regular battery, that is, you can even bring a wire from it, for example, to a car vacuum cleaner, a screwdriver. But the most interesting thing is that it is able to spin the starter of a motorcycle or car.
