I've found my 600cc motorcycle will start from the 400 farad bank as long as it has at least 10v.

I had bought a 350 farad kit from Ebay a while ago that included a printed circuit board and all the components for LED balancing. I found 1 of the LEDs had died, so I soldered in a new one. Then I found 2 of them dead a few days later... long story short, I think I need to figure out a better way to balance the capacitors. They will get out of balance when some have balance circuitry on them and others do not. It's worse than having no balance circuitry at all.

I've found balance boards on Amazon that might work, but the mixed reviews makes me think there's a good chance it would just fry.

I'm starting to see 3v rated caps, which means you could use 5 in series to get a 15v rather than using 6. Reducing the number of capacitors in series increases the overall available energy.

I don't know why pricing is continuing to stay so high, and I'm not seeing as many Maxwell products offered now that Tesla owns them.
