Generational LFP

[Trident]

After two years of full time use, including cooking on electric, making electrically heated hot water daily, etc I looked at the cycle count on my BMS and the expected cycle count from the EVE cells...

The batteries should start to show serious degradation of capacity (maybe 20% reduction) in 2119 .. I know cycle count is not the only factor but if this is true , my £1500 of EVE cells and BMS will average £15.78 per year of use. We get 100% power from solar for 10 months a year - I guess the panels will not last that long but three sets might last a century... My great grandchildren will be very happy I think

We are also fully electric but we don't get as much Sun as you, so ours will only last a paltry 44 years.

Waste of money then Best go back to lead acid

You may be ignoring calendar aging.

LiFePo4 cells lose capacity according to time as well as cycling. The rate of this varies according to temperature and SOC at which they're stored, but a good number for our mild climes plus reasonable care with storage is probably 1% a year.

"A" grade EVE 280K cells are shipped with 10% more capacity than nominal. It means it will take 10 years for them to reach their nominal capacity
