MSI STEALTH 15M use msiEcHelper or helper for set a new battery threshold?

[mati-fp]

In this function in operate.cpp,

void Operate::setBatteryThreshold(int value) const {
    if (msiEcHelper.hasBatteryEndThreshold())
        return msiEcHelper.setBatteryEndThreshold(value);
    if (value != getBatteryThreshold())
        helper.putValue(batteryThresholdAddress, value + 128);
}

The MSI STEALTH 15M use which helper for change the limits in the charging of the battery?
