BK: Basically a 3 person company, manufactures BL ESCs, distribute cells (which they match ant zap themselfe) boat hulls and other RC goodies. They also get motors manufactured under their name.

Lehner: Renowed company, sell mainly their well-known motors now, but used to manufacture ESCs back in the day.

Only what I heard, guys. So don't hold me for this info. Others may know more, but they are certainly 2 different companies! No doubt.
