Before I got the 18650's I was out of town on a military project and all the 123's were dead. I just stopped into the first drug store and bought 6 cr123 camera bateries.
Problem solved.
You're not going to do that with the Protege 14500's or whatever it is they're going to run the V2 off of.
Actually, you will be able to do that. The V2 is going to take the same RCR123a batteries as the V1, just not the 18650.
