What Batteries to use to make Silver Bullet a 7.4v?

[Sir_Lawrence]

I'm building another mod, but I need the size of batteries that the Silver Bullet uses. It take (2)rcr123a 3v batteries to make 6v. What batteries are the same size but each 3.7v? Can I use the same charger for the new batteries that I use for the rcr123a batteries?
Thanks

RCR123a batteries either come in 3.0v or 3.7v. Check out BatteryJunction.com You should be able to find what you are looking for there.

Note that lithiums charge HIGHER than stated voltage. My 3v. 123's charge to 3.7, bet you get over 8 v with 2) 3.7's, not good.
