I hate how battery systems are rated. They never give the full picture. "This is a MW system" cool, but how much storage?

It's in MWh, what more do you want?

[-] huquad@lemmy.ml 2 points 1 week ago

Many articles leave that out. The headline for instance only lists Ah

But isn't AHr a better measure for battery storage ?

[-] huquad@lemmy.ml 1 points 1 week ago

No, you're still missing voltage to give you the total energy storage, or Watt-hour (wh). For a cell of known chemistry, the voltage is implied. For example, lithium ion's nominal voltage is ~3.7V. However, the term "battery" is ambiguous. Could be one cell, could be many strapped together to form your "battery". See 12V lead acid batteries. Therefore, Ah is only half the answer.

Yeah, I really want to be impressed and am sure I will be. Just give me the specs
