Lumafield's Battery quality report: https://www.lumafield.com/battery-report

Could not download the report - had to provide personal info and then 'nothing' so far.

I got a link after entering my info. Also, I got an email with the link.

Here is the link from my email: Link
Not sure if it will work for others.

That way you don't get in trouble (probably not anyways) if they say you violated ToS

Thanks, I was able to download. It's interesting info!

My powerwall is mostly Samsung (12%), Panasonic (35%), and LG (53%). LG isn't mentioned in their study but I presume (hoping) they're better than worse. LG was early purchases, transitioned to Panasonic / Samsung in recent years.

Back when I was harvesting old laptop batteries, by far, the most issues I had were with the red Sony cells. I've only ever bought Samsung new. I bet LGs are good quality too, being a reputable name brand. Too bad they didn't test any EVE or Moli cells. I have heard good things about those. Never heard of Murata.

 

[OffGridInTheCity]

Agreed

Never heard of Murata.
