which light are you using, many flashlights can use cr123's but cannot take the extra voltage that the rcr123's put out.. You can fry your light using rechargeables..

Using 18650's is a better option but you will save a lot of time getting them from a us seller like lighthound.com

or ebay has some decent options.. the soshine cells and charger are very nice: http://cgi.ebay.com/18650-SOSHINE-Ch...item4cf2fd1bc4

less expensive alternative is dsd charger + UF cells: http://cgi.ebay.com/new-18650-charge...item2c5941e0d9
