The app displays the following functions in real time: - Voltage in volts (V) - Current in amperes (A) - Power in watts (W) - Capacity and remaining capacity in ampere hours (Ah) - Number of charging cycles - Charging/discharging allowed The battery transmits the information whether charging or discharging of the battery is "allowed" or "stopped" due to an error message, such as an increased temperature. Error messages that can be displayed below the state of charge in percent are: - Everything is OK! - The battery is too cold! - The battery is too hot! - There is a disbalance in the cells. Don't worry. If you use me, I'll even it out. - The charging voltage is too high. Please make sure your charger is not desulphating and charging below 14.4V. - The current you are charging with is too high! - You are trying to draw more current than I can supply. - One cell has too low a voltage. Please charge me! - The battery voltage is too low. Please charge me!
