Now then. When considering the Fluence as a purchase I watched just about every Youtube video I could lay my paws on. Some were in Danish, Russian, Hebrew, French, German, and (hardest of all) Australian. My favourite became an Irish one: Bob Flavin's review which I now know by heart: "the car is capable of speed...it's not a milk float" etc.
But then I got onto the really obcure ones , not least the training videos provided by Reno for their ZE technicians. If you don't know what the red, orange and blue zones of your Fluence are, I recommend this video! Also provides some nice background info and schematics. Sort of. Anyway, if you've got 11 mins, enjoy:
