    Hello Xie,

    If by improving your SoH, you mean increasing the longevity of your battery, then you will need

    • to discharge your battery at smaller rates (C/5). 
    • Make sure your learning cycle is done the right way

    FCC is equal to design capacity before a learning cycle. The SoH FCC is the first FCC after a learning cycle with simulate curretn at 25C

     SOH is defined as 100% * (FCC_SOH / Design Capacity).
