This is the Revamp Battery. It's a replacement for the standard lead-acid battery found in every car on the road. It's about the same price, and about the same size. It contains no lead, or acid. It does not produce explosive hydrogen gas when overcharged. The most toxic thing within it is acetophenone, a solvent used in blush and mascara. Unlike standard batteries, it has a current shut-off, so it won't make explode if you touch the terminals together. It won't overcharge, or overdraw. It just goes to sleep. So there's that. Unlike lead acid batteries, it will not leak and or explode in a car crash.

We're open sourcing the design after our crowd-funding campaign. It'll be reverse-engineered very quickly thereafter, so why not?
  • 5 × 2.4v 30Ah Prisimatic Lithium Titanate Cells Nanostructured anode lithium cells with an extremely long lifetime.
  • 6 × 0.1 kF Carbon Aerogel Supercapacitor Low energy density, but extreme power density.
  • 1 × 100kJ Pulse Switch However you'd like to switch the current. It's a lot of current.
  • 1 × Electrically and Thermally Insulated Casing Kiloamps hurt. Trust me. Have a physical layer of protection between you and the Joules. Trust me.
  • 2 × Lead-Free Terminals/Clamps Keep it RoHS

Thanks for entering the hackaday prize! I'm guessing from your tags that your battery is supercap based - can you tell us more about it? The more open the better for The Hackaday prize!

I'm thinking you will need a lot more to be a car battery but would work as a motorcycle battery. One question. does the battery have to be rectangle?

In testing, the 16Ah was nearly sufficient. Lead acids don't have discharge controllers or current sensors. Its enough that you can listen to the radio or leave the lights on and not worry. The motorcycle version will likely be 10Ah.

Shape is not fixed. That case was a rapid prototyped with lasered acrylic, and filled in with intumescent material.

What's the capacity like?

  Are you sure? yes | no

First version had 4Ah, second had 16Ah, third had 20Ah. Looking to settle at 30Ah.
