LiFePO4 in Surefire L4

Can I use 2 RCR123 LiFePO4 in Surefire L4?

You probably could but it would be poor runtime with the low power of that type of battery. You should get a 17670 which will work nicely in the L4 with much better current even though it is a lower voltage the L4 works well with it due to the step up circuit.
