[sdiy] Battery power for eurorack

[Didier Leplae]

I’m curious about the idea of using batteries for eurorack power. I am not an electrical engineer, so correct me if I’m wrong in thinking that battery power could potentially be very clean compared with the cheap power supplies many of us use.
Plus, of course the portability would be another great benefit.

Given recent advances in rechargeable battery technology, I wonder if it could be practical and not terribly expensive.

 I’m assuming you might need two or even three separate batteries to get the +12 , -12 and +5 volt supplies.

Perhaps someone has done this that I’m not aware of.
