RE: Hangar 9 33% Edge 540
Darrell,
I only expect a 5-7minute flight with this pack. The 4.2AH total is a bit low for drawing 30-50amps. The new 3.2AH cells will become available from Kokam USA this Winter in configurations up to 6s3p. A 10s3p configuration of these cells will provide a 10AH total capacity at current draws up to 180amps!
The other nice thing about the new packs will be the built-in cell balancing plug that taps into each individual cell to work with the new chargers...also due out this Winter.
