Hi folks, I'm sort of curious, in the modern era the M100's use of 1.5V alkalines is somewhat of a wasteful habit and they are slowly becoming less available than they used to be as everything goes LiIon.
Lithium batteries with builtin 1.5V regulators are nice for sure, but given that its switching converter is apparently known for not being the most reliable part of it (and seeing as it's driven by a discrete darlington, is probably not exactly the most efficient power circuit ever designed either), has anyone ever engineered a replacement with a modern 2-output POL regulator that would take 4 stacked lithiums as input? -- Erik
