I have schematics that came with kit from [KTA-ev.com](http://KTA-ev.com), but no detailed instructions on best grouping of components. I know the controller gets hot and needs to be mounted on AL plate… anything else? Does the DC-DC convertor get hot too? anything else need to be on a heat sink?

How about close-up pictures of ‘component boxes’, anybody have any good examples?
