NESSCAP 16V 583F Super Capacitor Battery 3500farad car Audio Amplifier 12V Solar Power System Home Battery Pack

This is one of the best super capacitors in the market. It is compact in size, but it is very strong electrical power. Although there is no case for them from the picture but when I received them, they were covered with clear hard plastic. It is used to cover the sensitive circuit boards and to help the capacitors staying together and to protect the user from getting electrocute. Thus, I do not need the cases for them. I installed two of them to my super capacitor batteries bank. I know they are very strong because although I was very careful during the installation, but I still have one-time short circuit. The spark melted a little bit of steel from a wrench and a little bit of steel from a nut that is used to join the batteries together.

Update: completed my fourth order. This seller is fantastic Great product and responsive and HONESTFirst: Love the product. Great capacitor and balance boards.

No issues other than a little longer delivery time

Will update. Seems like its as powerful as advertised.

I just got it in the mail. This capacitor bank was very well packaged and was also wrapped in clear plastic so dust couldn’t get in to it and looks like there was no damage in the transition of the product. Very satisfied in packaging. I will update on how well it works in the car audio subject.Update*: charged capacitor to 13.3 volts and had a 3 amp draw on it for a period of time. The voltage determination rate was .01 volt per minute.I then re-charged the capacitor to 13.3volts and let it sit at the voltage for a period of 4 days then checked. The voltage was 12.5volts.Lastly, I wired up the capacitor to my car for my audio sound system. (Before capacitor lights would dim aggressively when bass hit) after being put in when the bass hit there was zero dim during a very dark night.5 stars on packaging, voltage regulation, capacitance, and overall compactness of product. Very happy with my purchase now I don’t have to put so much stress on my alternator.
