Lipo - ESC - Motor combinations
If the 20C is continuous, burst capacity (usually &lt;10s) will likely be something like 30C so you should be fine. I am not sure what props etc you are running but 12A escs seem a bit low, as your motor / prop combination will determine the current draw, and the escs may burn on a sustained full throttle 'punch'. If your quad only draws what you believe it will draw, then your battery should be fine! (for reference I run 20A escs on a 225mm with 6inch standard two blade props / 2300kv 2205 motors, 621g flying weight (tilt rotor) - I use 1300mah, 4s, 40c (60c burst) with that combination, not optimal and I want bigger batteries). It will alsodepend how you intend to fly also, as racing will be more demanding than hovering, etc...
