A great video showing 5 new battery technologies for electric powered vehicles.
And what better way to put that electric technology to work than in a DMC-12. This video has all kinds of links to some of the components used in the conversion build.
One of the interesting new services I learned about is Big Battery https://bigbattery.com/ They can provide high power batteries to many kinds of custom built electric vehicles.
Another service of note in the last video is Send-Cut-Send https://sendcutsend.com/ This is a made in the USA (Reno NV) option Laser cut metal, it could be worth checking out for your next project.
