In PP3D we use optipower drone packs. 4s, 8Ah. I forget what the burst current is but it's 500A plus. To run PP3D we use 6 of these packs on the weapon giving the etek 12s (50v ish) and 16Ah. After a typical fight we had extracted around half this capacity. The drive uses a 3000Ah 6s pack which will typically run for a good 10 minutes on our T64 drive motors.
