[RE-wrenches] Powerwall and other Li

[Hilton Dier]

Has anyone calculated a lifetime cost per stored and delivered kWh for any of these lithium battery systems?

From the rough numbers I’ve come up with in the past it seems like daily cycling to avoid grid use would be a dead loss. The capital cost vs capacity and cycle life doesn’t add up. 

Also, I know mentioning this is out of line per list etiquette, but could people refrain from including 20 preceding messages in their posts? I tend to read this on my phone and my scrolling finger is getting shorter. Thanks!
