Answer to the question; Battery light flashes or stays red.
If the light on the control panel flashes red, it means that the battery is getting a bit empty and that it can be charged again. There is still enough to run at least 9 holes.
If the light is constantly red, it means that the battery is almost empty. You can still drive with it, but soon the trolley will stop and fall out.
It is then important to stop electronically, but put the wheels in freewheel and continue pushing. Otherwise, the battery will be discharged too much and may be damaged.
Do immediately charge the battery when you return home and do not leave it uncharged.
