A quick question on State of Health...
I have 3 Fox MIRA batteries installed in a garage in November 2023 and over this time averaging 0.67 cycles per day so not being worked that hard.
As expected the State of Health deteriorates over time however as of today it now stands at 91% which for batteries installed less than 2.5 years ago is a faster rate than I was expected. I know that the first few years are the worse and it 'should' stabilise but what are other's experiences as this seems to me to be just a little bit too rapid to me?
If you have done approx 600 or so cycles in the 2.5 years, then if the lifespan is 6000 cycles (it does vary) that makes about 10%
Hopefully some others will chime in shortly with their SoH values/cycles.

Fox warranties batteries for 80% capacity after 5 years, or at least they do in Australia and they offer 10yrs warranty for the batteries I have, but the same battery model in the UK comes with 12 yrs warranty, which I can only put down to the climate being hotter here.
I'd like to know how they calculate SoH.
The data logger collects and sends Fox more information then displayed to owners, such as hours charging in extreme temperatures.
