You've got data showing less degradation per year on Lizard packs? Most of the posts I've seen on these forums say Lizard/30kWh are degrading plenty fast.
You're very much half right. While the 24kwh Lizard packs seem to be holding up very well, the 30kwh packs don't. They may very well represent a step backwards in longevity. I really hope that the 40kwh packs don't degrade like the 30s...
