Need Help

If some one can put me out of my misery It would be much appriciated. I have been reading off and on for two days trying to find out which rechargable batteries I can use in a stock Surefire 6P led with the stock P60L led module in it. It seems that all of the references to rechargables is for a non surfire aftermarket drop-in. I am very happy with the amount of light that the stock 6p LED puts out and only interested in a rechargable battery source that will help relieve my battery usage issue. Will two AW RCR123 3.7v 750mah protected cells work? What is the input voltage range of the surefire p60l module? Thanks in advance for the help.
