RE: Mini Dragonfly help
Roofus4, I am using a Thunder Power 860 mah...fireplug explained how I can use one. I have never given it full throttle...that would most likely burn up the 3-in-1 board. I have not had any issues yet...be careful, however, to monitor you battery voltage because the voltage cutoff for the board is 5V. It lasts at least 20 minutes.
