Yes, another reference for the Thundersky Winston (TSWB) Lithium Iron Phosphate (LFP) cells. The photos show a pack made of cells from January 2010. The first generation LFP cells TS-LFP150AH with production date 20100130.
This pack is installed in an EV conversion project and has been providing the traction power for 10 years.
There is a question to ask: What is the real history of your supplier and how can they demonstrate that their products can really last 10, 20, 30 years?
In 2010, TSWB was already producing monolithic single 150AH site cells, while the other “top leading brands” (like A123 [bankrupt], Altairnano [bankrupt], Valence [bankrupt]) were boasting about just 20 Ah pouch cells.
We keep asking again: What was your manufacturer doing in 2010? This is what makes the difference.
