GivTCP Understanding the battery data

Just installed givtcp and I'm trying to understand the battery data section. Omitting the individual cells the data for my two batteries are:

"Battery_Details": {
        "BK2246G121": {
            "Battery_Capacity": 98.75,
            "Battery_Cells": 16,
            "Battery_Cycles": 182,
            "Battery_Design_Capacity": 102.0,
            "Battery_Firmware_Version": 3012,
            "Battery_Remaining_Capacity": 77.36,
            "Battery_SOC": 42,
            "Battery_Temperature": 26.8,
            "Battery_USB_present": true,
            "Battery_Voltage": 51.034
        }
    },

and

"Battery_Details": {
        "BK2246G135": {
            "Battery_Capacity": 98.37,
            "Battery_Cycles": 164,
            "Battery_Design_Capacity": 102.0,
            "Battery_Firmware_Version": 3012,
            "Battery_Remaining_Capacity": 93.28,
            "Battery_Serial_Number": "BK2246G135",
            "Battery_SOC": 95,
            "Battery_Temperature": 22.5,
            "Battery_USB_present": true,
            "Battery_Voltage": 52.946
        }
    },

I'm trying to relate the capacity, remaining_capacity, and SOC figures with the % remaining that I see in the app, but none of it seems consistent.

For battery 121:
remaining/capacity = 77.36/98.75 = 78%, but SOC=42 and the app says 24%

For battery 135:
remaining/capacity = 93.28/98.37=94% but SOC=95 and app says 97%

I'm sure I'm simply misunderstanding the numbers: could someone explain what they mean please, or point me to some tech info that explains it!

Thanks,
Ian.

I’ve never looked at the battery data before, but looking at my 5.2 (the 9.5 is currently empty):

Battery capacity 98.5
Battery remaining capacity 46.69
Battery soc 47%

And 46.69/98.5 = 47.2% so seems correct to me

Worth noting that there is also a soc reported by the inverter. This is often a % or two different than the battery soc. At the moment my inverter is reporting 42%. No idea why the two values and why the inverter and battery socs are different with only one battery per inverter, but that’s the way it is

It's to do with the battery buffers.
The battery's all have 20% buffers built in, split 15% - 95% which corresponds to their rated capacity. (I.e 10.24kWh actual cell capacity, less 20% gives you the 8.2kWh pack)
So battery SOC is the batteries true SOC - ranging from 15% to 95% (unless your doing a calibration in which case you'll see it go from 0-100)
Inverter SOC is it rescaling the 15 to 95 part to the 4-100% for the end user.
It basically stops the end user being able to use the buffers.
