The new MaxAmps packs came today!
These are sweet batteries. The first thing I did after I unwrapped them was cycle them. Discharge to 3.2V/cell at 1C (4A). Then charge at 1C. They
both took over
3930 mAh! I'd imagine that they're slighly underrated as far as capacity goes. If I were to discharge to 3V/cell they would definitely take more than 4000 mAh during the subsequent charge cycle.
Did I mention that they fit absolutely perfectly next to the chassis? See! It does pay to measure twice! I also installed a set of 5.5mm bullet connectors on each pack.

Perfect!
