Looks awesome! How long will it run on a single charge?
After some live testing today I got about three and a half hour. And a spare battery is easy to have with you if you want longer time.
Haven't tested it with this setup yet that uses 19 LEDs the old on that use 8 LEDs runs for 3h+ on a 110mAh lipo.
