Wiring Diagram for NB, 18500, Lux Rebel, Recharge Port, and two accent LEDs

Wiring diagram from my latest saber, a Luke ANH Graflex.

I used a 3.7V Li-Ion 18500 cell, Nano Biscotte, recharge port, a Lux Rebel blue, and two different sized accent LEDs for the crystal chamber.

It worked like a charm.

Can I ask what kind of usage you get out of a single charge on the 18500?
I ask because I posted a question here asking if it's worth it to use one in my build.
Thanks,
Al

Not sure. Ive never run it down. I chare it regularly.
