My H150 has arrived and I like it!

Or at least file it down so it cannot make contact with the battery?

Probably yes, if you were able to unscrew the head (they use very good glue). Also there are several other components at the battery side of the driver. Lastly there's always the chance other components fall off from the heat, maybe at the back side.

So yes, it's possible, but difficult. The good thing: You don't have to worry about it, Skilhunt is recalling the H150 and will exchange them for a fixed version!
