How much lithium is enough?

[JockandRita]

But the cells have 8,000 cycles

Yes, the ones you have your eye on, not the ones I already have installed, but nonetheless, they'll still outsee me.

Cheers,

Jock.

4000 or 8000 is the difference between a very long time and an extremely long time IF they actually will do it. I suspect that’s for perfect cells under lab conditions. B grade are far from perfect, so 8000 is laughable. The cell biz is full of sales BS. Still if they’re cheap enough probably worth it as built batteries are still fairly expensive in the UK.

Agree, calendar age will creep in well before the cell count will be used up. Electrolyte used in lifepo4 is organic, and will degrade with time, use or no use, and more so at elevated temperature; specially temperatures above 35C deg. Cycle count will be 150-200 per year max, so 4000 cycles we are looking at close to 20 years.

Even at 2000 cycles within the 6 x year warranty, I'll still be happy as it's 4 x times that of most LA batteries.

Based on those (no doubt) more realistc figures Raul, we are surely still looking at 6 x years plus.

Cheers,

Jock.

I have no doubt they can easily do 20 years as long you don't cycle the full 100% all the time.
