Why does the EVO remote show a lower battery level than actual?
You may notice that the battery level displayed on the EVO remote appears lower before triggering the motor, and then updates to a higher (more accurate) value once the trigger is engaged.
This is normal behavior and not a fault.
The discrepancy is caused by how the ESC initializes and reads battery voltage. At startup, the batteries are not yet fully supplying current, so the ESC does not capture the full voltage accurately during its initial measurement.
Once the system is activated (by pressing the trigger), the ESC refreshes its voltage reading and displays a more accurate battery level.
In short:
- At startup: The initial voltage reading may appear lower
- After first trigger: Voltage updates to the correct battery level
No action is required; this is expected behavior related to the ESC’s initial voltage detection process.
