Quadrotor: Two Parallel Lipo vs. One big Lipo

Here is the conundrum:

A) 2 bateries 3000 mAh in parallel, powering the four engines.

B) 2 bateries 3000 mAh, each powering two engines.

C) 1 battery 6000 mAh, powering the four engines.

Also, if bateries are in parallel, how is the voltage monitoring affected? Could one relly on monitoring only one battery?

I assume they will balance themselves, is that an issue, considering both packs will be exactly the same model (and will always be used in the same setup, so same age and cycles).

For motors, its the Towerpro 3015-7 (re-glued magnets).

  • 1000 RPM/v
  • 470 W
  • Max Eff Current: 30A
  • Max current: 40A

Propellers probably going to be 9x6, or 9x5, or 10x4.7
