I just got back from a bike trip (in the friggin rain again with 25mph winds, but I really needed to go, my cats were starving) and I took the pack off the bike to recharge the cells and one of the cells are bad, that's the problem. So I just tossed it aside to see if it can be reconditioned and I put a different (but same brand/model) in the charger. I think most of the voltage drop was coming from that 1 cell, I'll have to check it again after they are all charged.
I'm not sure of the gauge of the wires (I threw the packaging away a long time ago), but both(red wire and black wire) are pretty heavy, the black one is solid.

I got my bike light through Amazon, probably much less than the claimed lumens, but still plenty bright and reasonable price. Power is from a pack with 4 18650 cells and runs for almost 4 hours on high:

How is the beam?
Are 18650 cells primary or rechargeable?
Thanks for the input from everyone.
