To add to this. So, I just got this guy in the mail today and I thought I would share my initial thoughts. The pack is very well built, reminds me of the Zippy's tremendously. All cells where at 3.8, and nothing visually wrong with the battery. The shrink wrap is a cool clear blue, and looks stellar. The butt end is exposed, the front is covered by a layer of fiber tape. The only peeve I have thus far, unless it fails upon charge/running, is that it only has 12 gauge wire. For a 40c 14.8 volt battery you would think a high gauge perhaps.

As for an update on the 2s hardcase, I have devoted this pack to racing. It is the main pack I use on my Slash 4x4. I start the night with a smaller 25c 4000 mah pack for practice since it is just practice. Than I run the Blue Lipo for the 2 heats and the main, charging @ 8-10 amps in between. The pack gets slightly warm as does all lipos, but after my turn at marshaling it is usually cool enough to start a charge. No poofing yet and no signs of wear. Holds up great to the needs of the VXL. However I may need a heatsink for that motor shortly, boy it gets hot.
