Of all the EV conversions of cars and trucks, OEM EV systems in yachts, cars, vans, etc., a super fun and memorable project was designing and building a racing battery for Hypercraft on contract with Kindig-It.

The vehicle was built out to be a cherry-red 1953 Corvette. But it wasn't a restomod. Everything was created new, from the rolling frame, to the carbon fiber body. The EV was to be powered by twin Yasa axial flux motors, and run off an 800v Lithium battery.

In designing the 800v battery, we were limited because the carbon fiber body was already complete and designed for the original 1953 dimensions, and not around a giant battery platform. We had the driveline tunnel, transmission and engine bay for space to work with and maximize the Ah capacity of the battery and battery management electronics, and battery cooling system.

Using over 4,000pcs of 4a 21700 style Lithium-Ion round cells, we built a 67KWh Lithium beast.

>Cells, cooling, battery management electronics, fuses, etc. all contained with the total enclosure

>Designed to be swappable (from under the EV), with valved coolant ports and quick release HV disconnects

>Redundant cooling protection. Active cooling via traditional water/glycol, and passive heat absorbant foam that isolates thermal runaway to a single cell

We built something beautiful and fast to go into something even more beautiful and fast. See the results for yourself:

Each project we build combines our passion for integrating unique energy solutions into intuitive hard-tech products.
