Menu Option 5, Battery Status
Menu option 5 shows the difference (as a percentage) between the highest measured
cell voltage and the lowest measured cell voltage, measured at the same time.
The BMS tries to balance the charging status of all 4 battery cells to the same level. By
measuring the difference between the highest cell voltage and the lowest cell voltage,
the actual battery status is determined. This status can be shown by activating menu 5.
To get a comparable result, this battery status check is done best directly after use/
flight.
BMS Error Mode
If during the charging process the LEDs are lit alternatively LED2 and LED4 ON with
LED3 ON, the charging process is interrupted for one of the following reasons:
• The battery cells are too hot or too cold
• Charge Control Circuitry too hot
The charging process will resume automatically once the temperature of the cells is
normalized.
When the battery shows LED1 ON and LED5 ON alternating with LED2 and LED4 ON,
the battery was operated out of specifications (e. g. too hot during discharge).
When a battery shows this behavior, it can still be used to discharge its remaining
capacity, but it must not be used anymore.
