Problem with Mbot Ranger


When ever I try to drive my Mbot ranger at full speed it stops and beeps then repeats. I have changed the batteries , Upgraded firmware, and reset the default program.
Any Ideas?


Hi, the repeating beeps sounds like that the Ranger doesn’t have enough power. What kinds of batteries do you use for Ranger? According to our test and research, it is suggested to use rechargeable Li-ion battery or rechargeable nickel-metal hydride, nickel-cadmium which can be bought from amazon or local shop. Or Alkaline battery with good quality like Energizer, DURACELL.
