Supercapacitor Safe to Use with a Lithium Starter Battery?
This is why a super capacitor in conjunction with a lead acid, or lithium battery works so well. The batteries store a lot of juice. The super capacitor stores relatively little, but it can let go of it hundreds of times faster, than any lead acid, or lithium battery. Super caps + batteries are a match made in heaven. The best if both worlds.
