I was browsing through a local computer parts store and came across a 1/3AA 3.6v 160mah NiMH battery today. I'm not an electronics guy by any stretch, but I've seen the 2.4v mod and have heard of some trying a 3.6v mod. What do you guys think about using this battery with the bits or zips? It is larger and heavier, but not much more than 2 1/3AAA NiMH. I'm kind of curious about whether the voltage or current would be too risky.
