Disregard the Daly app. The Daly BMS’s don’t coulomb count correctly, especially at low currents.
You can reset a coulomb counting (one with a shunt) SOC once the charger cuts off. Settling voltage will not lower the SOC as the SOC relies on current out vs current in, not voltage.
If your battery is cutting off when your SOC meter gets to 17% then the battery capacity set in your SOC meter is 17% too high. So if you have 100Ah set as the battery capacity, lower it to 83Ah.
