You have a source for that 2000 cycle number? In reality, with somewhat deep discharges, the number is actually closer to 600-700, before experiencing significant capacity losses of ~15-20%. At 2000 cycles, I'd imagine the capacity to be somewhere in the range of 50% of initial. Now that doesn't matter for utility scale, because you can easily keep that 50% pack in operation, as long as your total capacity stays the same (adding new packs), but for smaller scale, it's quite significant. Look up Nissan Leaf range degradation and you'll see what I mean.
