The super capacitor has been installed into my pickup and it's working great.
It was done for smoothing out the electrical system and adding a little boost in cold weather.
First day I gave it whirl, this is what the conditions looked like:
That's ice on the windshield exterior.
The truck has never had a hard time starting, this isn't a Band-Aid, but definitely starts quicker in cold weather now though. Not only does the starter get a boost, but the ignition also has plenty of power.
I can post more detail of the installation, but in short, I bought the smallest project box I could, two of them actually, and cut an opening in one top because it was too short, and bolted another top, on top. I wanted a clear top to see the LEDs, which didn't work out because of the position, but still I wanted the option.
It's a nice project box, but cream colored, so I painted it black. There's also mounting bosses in the floor of it, but I supported the capacitor module with foam instead. Being plastic, I had to make certain to use custom spacing to mount it to the non-flat area, so it wouldn't twist and the top not fit.
There's more small details I added, like venting.
So far, it's been great. The electrical system is rock steady. When I turn the headlights on, it doesn't even flinch, but all the external lights on the pickup have been converted to LED, including the headlights.
I had tested the near fully charged super capacitor module on my 200ES, without a battery, and it started the trike several times in a row on it's own. This thing packs a punch, and it may be a placebo, but I'd swear the radio in my truck sounds better too (just four 5 1/4 and one 12).
