Problem with 4wd hat

Dear, does anyone know how to inform the meanings of the leds on the 4wd hat plate. My PICAR 4wd, stopped working and two leds are lit red

The LED on the driver cap board is the battery power indicator, two LEDs are on, representing the battery is fully charged state, two LEDs are off, representing the battery is dead, please charge the battery in time.

You said picar 4wd stop working, the LED is still on, did not understand what you mean.
Please describe the problem in detail, if you can provide a video of the problem will be better.
Convenient for us to quickly analyze the problem.
