I was at the place where these LFP cells went to back in April 2023. 16 of the cells were still in operation, 2 parallel, 8 series. 24v solar system. The owner was just here last week and picked up another 8 Winston cells x 200Ah, second hand from a stripped EV conversion. He said the 16 were still operating but with significant reduction in capacity. Remember... history check.... these LFP cells were very much abused in EV Hilux. They are now close on 15 years old. If they were new and used only on a solar system, they would be good for a lot longer.
LFP chemistry is said to be 2000-3000 cycle life.
The new LYP chemistry is said to be 5000+ cycle life.
