Ultra-capacitor review

[Lund]

I used Earth X religiously for awhile on everything I owned. They were great batteries and lightweight with killer Cold Crank Amps but they are proving to only last a small number of years. Really interesting in the ultra capacitor solution. Use them at work in industrial applications so a consumer application for sleds, bikes, etc would be great.

I've been using Antigravity, no issues and imo descent life. easy 3 season maybe even 4 if you take care of it with maintenance charge.
