It's been just over 3 years since my #tesla #Powerwall was installed and I got curious to see what the degradation had been. I quickly realised I had not been capturing a key API page from my powerwall.. so sadly I've lost any hisotircal data. But it's been added to my TeleGraf config and I've updated my dashboards to display it.
Quick and dirty number, looks to be about 5% deg after 36 months of usage, on approximately 825 'full' cycles. Not too bad!
