Bizarre. With an operating voltage of 3.6 rather than 4.5, you'd think NiMH cells would be safe as milk. I wonder if it has something to do with boost mode drawing too much current for the cells? Not to mention there's a huge array of NiMH cells on the market, and I wonder what types have failed?

Since it's non-regulated, the Myo doesn't perform all that stably with alkaline cells, dropping off steadily in output. But that's what they're limiting us to.
