I bought this 500 lm two pack for coworker and kept one. I had a surprise when I disassembled the tail switch
It has an XP-G3
and runs on 4 AA
I was hoping to power it with a 26650 but the driver contact is almost 1/4” below the retaining ring and the head is glued(?) on. I installed some Eneloops and measured 2.5 amps.
How do I go about getting that head off and should I leave the driver as is? Can this driver handle 2S Li-ion (8.4V) if it’s the same one found in the XP-L light above?
