4 long beeps and 2 short beeps

Recommended Posts

It Keeps doing 4 long beeps then 2 short beeps and when I try to access it on the ninebot app it comes up with a popup saying "Tip External battery communication error, please check the battery, master control and related cables." What do I do?

Welcome ,

I don’t think I can help but more info will be needed for those that can. 

What model Ninebot do you have? How old is it? How many miles are on it? 

This is a complete guess from me but it sounds like your batteries are bad or have dropped below an acceptable level. 

@Mono @esaj any guesses?
