After roughly 350 charge-discharge cycles, my 5.12kw 48V LifePower4 battery's State of Health (SOH) dipped 0.3% to 99.7%. The Growatt SPF3000 All-in-one is set to cycle the battery between a 20% and 91% state of charge, but there have been one or two glitches where these parameters were exceeded. All that said, I'm wondering if a 0.3% decline in SOH over 350 cycles is reasonable, and what a chart of SOH vs Charge Cycles will look like over the estimated life of the battery (7000 cycles per the literature). Thoughts?
