The Lizard pack is the 2015 / 2016 24kwh pack that Nissan developed so they wouldn't have to replace as many degraded batteries under warranty. It is more tolerant of heat, although it still will degrade in extreme heat or sustained high heat. The Lettuce pack is the 30 kilowatt-hour pack. Nissan named the first, and I named the second. When you see the terms Canary pack and Wolf pack, those are named by me as well. Canary (2011-3/2013) was the first generation, and if it got even warm for long periods, it degraded rapidly. The Wolf pack (4/2013-2014) was much improved, and is about the same, longevity-wise, as the Lizard pack in cooler climates. It does, like its namesake, tend to suffer in high temps.
These are how the packs run in North America. We aren't sure about Europe, except that they got the Canary and Lizard packs in about the same time frames as North America.
