    >CATL attributes the longevity of these batteries to their new 530 Ah lithium ferrophosphate (LFP) prismatic battery cells. The battery lineup also includes the Tener BESS unit, which **CATL claims will not degrade during its first five years of operation.**

    I think the warranty is the interesting part of this post.

    Sure, when making the investment calculations, you have to take degradation into account. But it means that nowadays, with some battery storage systems, you can calculate with a 30-year lifetime.

  2. Whats really amazing about this is that the actual footprint of the containers looks to be well under 10 acres.
