Electric Go-Kart Made From Off The Shelf Components

Eletctric go kart
What¬†would you do with a catalog of parts and a nice budget? [Ben Rothschild] decided to build an electric go-kart from scratch, for a contest he’s trying to win.

He designed the entire go-kart in 3D CAD using off the shelf components to speed up assembly. The frame is made of aluminum extrusion with t-bolt brackets, and he’s using modified FIRST Robotics wheels with standard #25 chain and sprockets.

Two 1850W Turnigy SK3 brushless motors make up the drive system, equivalent to almost a 5HP engine — except with a constant torque profile, meaning it’ll have no problem going up hills at 3km/h or 30km/h, no gearing necessary! To power the beast he’s using four hard-shell LiPo batteries (4S1P), which are rated for 14.8V and 5Ah. Two el cheap-o 24V 500W speed controllers (slightly concerning) provide the control system, which he may plan to upgrade in the near future.

The test drive video is a bit short, but it looks like with a bit more work this go-kart could have a lot of potential!
