@acharnley, not sure if you are aware of the Eurobike 2016 trade fair in Friedrichshafen from August 31st to September 4th, which sounds like a great opportunity to get in contact with basically everybody in the German bicycle business.

It's probably too late and too expensive to set up your own booth there, but maybe you can find a company that is willing to host you. At least you could go there an try to talk to the distributors at their booths.

PS: the Forumslader is not your direct competitor, as it incorporates "cache" batteries. But Jens and his team put a lot of effort into optimizing it, and the diagram you saw is only a very small portition of the results of their measurements.

Btw, what is that black blob on the output cable - a capacitor that was too big to fit into the housing?
