My ultimate battery mods: 4.5V & 12V
 

4.5V : 3 1.5V button cells taped together (exact same size as the 1.2V that comes with the Bit) - hauls ass

12V: 2/3AAA 12V battery that sits on top of the PCB cover - hauls as (sometimes, other times doesn't work) onyl set back is that it starts to fry the PCB after a short run.

So how long do the button cells last?

I'm not sure, I took some out of my laser pointer (that was almost dead) and used so they died pretty quick. I am gonna go get some fresh ones soon, so I will tell you then.

can we see some pics?:D

Running 10 times the designated voltage on anything will tend to fry it. Think of those innocent little resistors, made for 1.2 volts, and you're destroying them with a 12 volt current. You monster!

muhahahahaha, it's so fun :D

is it possoble that we can see any pics here?:confused:

Maybe, it depends if my digital camera works anymore.
