That's true, which makes them perfect for Powerwall-type backup power, where weight is not a concern and the number of cycles will be very low. The other way to deal with low cycle count is to keep the cells only half-charged and minimize the excursions from that. A large pack that goes from 40 to 60 percent daily will last eons compared to one cycled from 90 to 10 percent. From what I understand, the degradation of the cell is not linear with the discharge excursion. So you may have exponentially better battery life the narrower of charge band you keep it in. If anyone has more detailed information let me know, I'd like to see better numbers.
