5th cell... has anyone seen this?
 

I found this guy trying to sell this xmod with 5 cells. This is what he wrote:

"A holder for a fifth AAA battery. These were made to use 4 AAA batteries. If you use standard 1.5volt non-rechargeables that is 6volts. If you use NiCd or NIMH at only 1.2volt per cell you end up with only 4.8v. This modification will let you add a fifth nicd or nimh cell to get a full 6Volts! This has not been tested with 5 alkalines which would give a whopping 7.5v, you can try that at your own risk for even more speed."

I was wondering if anyone else here has seen anything else like this or has tried it.

It wouldnt be that hard,

what is the max voltage these things can take?

Not sure. He doesn't sound that sure about useing 5 1.5v aaa's. But i thought it would be kind of cool to get the 1.2v's back that you lose useing the rechargeable nihm's.
