Confirmation of SOC vs. Voltage Chart

[Tom47]

I found this chart online for 48 volt, LFP batteries. Although it was pertaining to off-grid systems, I feel it should be applicable to golf carts also.

It was interesting to see the voltage drop from 100% to 99.5% and again to 99%. It appears 99% is what my ECO pack charges to when the charger automatically shuts off before the timer. The last time I watched it, the voltage was 54.65. After 30 minutes or so, it settled to 53.85.

Do you see any red flags in this chart or in my data?

Thank you for your input.
