Seth, The pack was carted out to me just before 11 AM and I took off at 3 PM with the cells in the back of the Prius (again bolted together in the original end plates to avoid having cells shift around in my car and short-circus as Bob Rice would say) I was prepared with a lot of tools, so I did not have to search or buy things like the security Torx, I had it ready to use in my car next to the pack. Mostly I used the 10mm and 1/2" socket with a short extension and my small ratchet. I had brought my 3/8" drive ratchet and 3 ft handle extension (steel pipe) which I did not need, but I used the large ratchet and a 16mm socket for undoing a reinforcement bar that goes across the pack between the front 4 stacks of 4 cells and the middle stacks of 2 cells. I needed the 2 crow bars that I also brought to lift the rear single stack of 24 cells to undo the bolts that were slightly hidden inside the bottom shell as I forgot to bring an open ended 10mm wrench, so I only had the socket which needs to have clear space in front in order to work.
I will soon know the difference as I am also planning to buy a 2015 Leaf for the pack and part out the rest of the car, since I want tocombine 2 Leaf packs in my S10. Thermal management: there is nothing to regulate the temp in a 2011 pack, it simply has a high voltage connector and a control connector, the pack is sealed beyond that. I have heard that later packs have a battery heater so I presume that the pack is still sealed but the control interface can enable a heater that is attached to the internal DC bus. The BMS does measure the temp of several spread-out cells, I believe I removed 4 temp sensors (and retained them to be used on my S10 when I re-install this pack and BMS) which looked like simple pt1000 metal tubes held in place with a plastic clip.

How long did that take you? Do you know what the difference is between the 2011/12 vs 2013-2015 packs? Also, is there some kind of thermal management?
