Picked up a 1200 lumen Olight PL-2 Valkyrie on a recent sale for $50 shipped. What protected RCR123A's would you folks recommend for use in this little lumen Monster? Will run-time be less than standard CR123A's? BTW, I have a XTAR VP2 for charging duty.
You're better off just trying out a naked/unprotected a 2500mAh 4.35v Sanyo UR16650ZTA cell if you have a positive spring at the positive end of the light, otherwise, you'll need to find one with a button top added by a third party.
You have the Xtar VP2, so you can charge up 4.35v cells and that should power up the WL.
You can look for a protected cell with button top, but it will only charge up to the typical 4.20v, since the protection circuit ceases charging at ~4.20v.
You're only out a $6 cell to run the experiment. Two RCR123 3.2v cells are generally crappy by nature and don't have the capacity, although they'll work.
Look to K2 Energy, marketed by SureFire and/or the Tenergy brand. Your VP2 can charge them up properly.
