g00fba11,
Right now, I have standard 9v batteries. Currently on the prowl for something better, haven't had much time to start crunching number on it yet...I
may make a DC-DC converter to take super common cell phone / camera batteries from 3-5v up to 12v. (A 1500mA cell battery should be able to run both
of my fans for ~5 hours from my math...)
Kites: 16m PL Scorpion, 9m & 14m 06 Best Waroo
Vehicles: Thrift store snowboard, fraken-ATB, Old Litewave water board.
