Iken..I saw you post you are hoping to carry the CR2. I would avoid doing so in the US. If someone has an accident, you will be held liable in a way that the Chinese manufacturers are not. Definitely not worth the risk.
You definitely have a pure valid point Nuck, Thank you for looking out man, I really appreciate it. So
No Go on cr2's if everything falls together. Its a shame cause thats what I prefer.

Protected 18650 and cr-123a's will be the ticket then. Its cool because I just found a nice uni charger them, couldnt find one for all
three types though, that is if people dont mind using dimes (on the negative end) for spacers haha
