Hi

Yes, I made them myself, at the university where I study. I used carbon prepreg, in this case twill with roughly 200 gsm. For the battery trays, I used a positive mould (plug) made of wood, which I simply cut to the size of the batteries plus some additional space. I used release film and laid three layers of prepreg onto the mould. Then I put them in a vacuum bag and into the autoclave at 2 bar pressure and 130°C to cure for two hours.

One battery tray (without velcro strap and double-sided tape) weighs 25 g. The carbon stripes for mounting with screws are glued on.

I will try to go to the race track tomorrow, to find out the runtime, but the weather is a bit unsure.
