I wa not real happy with run time with CygoLite-Hotshot-Pro-150-Lumens-LED.
(Even on blink mode)

It has a built in 800 mah LiIon battery.

Made an external battery pack using 18650s with a 5000 mah capacity.

The UltraFire batts are overrated and I have much better ones.

But I want to use them up.

Next project is the make my lights harder to steal.
Any ideas would be appreciated.

Looks good, running both lights from one pack makes sense.

All rechargable tail lights have too-small batteries. It would be
great if someone made one that took a single 18650.
