Super Capacitor Battery Charger DIY kit
with AC wall supply - 200F @ 5.4v COOL!
This listing is for a DIT super capacitor battery charger kit with an on board 200F 5.4v capacitor bank. It is extremely easy to use! You built it yourself! Watch the video above for a full set of assembly instructions. Below, you can find another video that offers a full demonstration of how the device works. This kit was loosely based on and instructable that I published a few years back. Said instructable is listed below. This board acts to charge the capacitor bank to roughly 5.3v, then disconnects power completely via an on board relay. When the device detects that the voltage on the capacitor bank is roughly 5.3v, the charge disconnects completely, and there is no back powering. The charge on the capacitor bank can be accessed via an on board output terminal block. We also sell these fully assembled and tested for a few dollars more, so check out our store!
Instructable: http://www.instructables.com/id/The-Forever-Rechargeable-VARIABLE-Super-Capacitor-/
Operation:
When you plug your 9v wall transformer into the 5mm power jack on the board, an on board LED will flash three times, and then you will hear a click. This is the charge relay turning on. the on board display will show you how much voltage is on the capacitor bank. When the capacitor bank reaches around 5.3v, the LED will start flashing, and the relay will disconnect, and re-connect to the input voltage source, which is roughly 9v. To reiterate, when the capacitors are charging, you will see the voltage on the caps. When charging has completed, the on board LED will continue to flash over and over until you disconnect power, and the voltage display will show you the input voltage source. When your capacitor bank is charged, you can access the isolated power of the capacitor bank via an output terminal block. There are two pins on the terminal block. The first is labelled: V+, which is your positive capacitor voltage. The other pin is GND, which is your DC output ground line.
Warnings & Recommendations:
1) Be careful NEVER to short the capacitors. If you short the capacitor output block, you will set the traces on fire. Super caps will discharge all that they can very quickly. As well, if you short the traces to the capacitors underneath the board, you can have a fire hazard on your hands. There are four mounting holes. One on each corner. Make sure to take advantage of them.
What Is Included:
1) All of the components talked about in the video, including the custom PCB.
