SimpliPhi 3.8 @ 48V - AH capacity

The battery specification claims 75AH capacity (I suspect @ 100H) and 60A useable (80% DoD).

What have folks decided to use for capacity in the FNDC? How did you derive the figure?

Thanks Greg. We're working with 8 monoblocks.

SimpliPhi uses some fairly high rate for discharge metrics, and I'm trying to get a read on what folks found as practical capacity measure.

No FNDC with Skybox, however.
