Could the ESC on this AIO board support really 4S battery?
Yes. But please pay more attention to the motors. Here are two situations that the motor will burn itself and then the ESC frequently.
Situation 1: The motor's KV value is too high and could not stand the 4S power. For example, the BETAFPV 1105 6000KV motors could not stand the 4S power in aggressive flying. So we are working on a lower KV 1105 motor that could use with 4S battery. It will be released soon.
Situation 2: A poor quality motor will result in the fire accident in 4S power.
For the moment, no 0x0x/1102/1103 motors could stand 4S power for the moment in the market. Please make sure your motors could support the 4S battery before any try.

Status LED
There are 3 LEDs on the bottom of the board to indicate the status, including Receiver LED ( Green), FC Status LED ( Blue ) and FC Power LED ( Red ).
LED | Status | Description |
Mode LED (Green) | Solid | Horizon Mode/ Angle Mode |
Mode LED (Green) | Extinguished | Acro Mode |
Power LED (Red) | Solid | Power on |
Status LED (Blue) | Solid | Motor Armed |
Built-in Current Meter
This is our first whoop FC board that have current sensor built-in. So no need to use the virtual current meter and you could get a more accurate current value. In order to use this current sensor hardware, some configurations in Betaflight GUI are needed. In the "Power & Battery" tab:
Then when flying, you could find the real current value from the OSD information. Of course, the current sensor is configured well in the factory and you do not need to change it as usual.
