How to build a Supercapacitor Power Bank. In this video, I tried to make a supercapacitor power bank at home. I used supercapacitor balancing boards to assemble supercaps in series and parallel safely. Balancing boards protect capacitors from over voltage damage. Each capacitor is rated 2.7V 500F. The total value of all 10 supercaps is 13.5V 200F. The average charging time for this pack was 8 minutes when I used car battery slow charger. For further information, watch my Supercapacitor 1 and 2 videos. The links are below. If you like this video, kindly subscribe and share pls.
