Hello,
I have an ES1 + external battery.
Sometimes I see on the dashboard this error: Error code 41 (External battery overheat)

What should I do? Is it a problem of the external battery or a scooter problem?
My scooter is new and in warranty, so I could ask for a replace.

I have the same issue. ES1 + External battery ---> 25 km/h. I flashed a custom firmware ESL but I don't see any change about speed. I think that last production batches have this hardware limit or something else. A friend of mine with the same configuration reach 28-29 km/h, but his scooter is 1 yea...

Hello,
I have a Ninebot ES1 with firmware 1.5.1 installed.
I would like to know if I can hack my scooter writing a custom firmware with the Android NineFlasher/XiaoFlasher app.

Anyone have ever done it?

Thanks
Roberto

Hello,
without disassembly my scooter is it possible to flash a custom firmware to my ES1?
I don't understand this.

Hello,
I downloaded the ESDownG app and I tried to connect to my ES1 Kickscooter.
The app was able to connect to the scooter, so I can flash a new firmware without disassembly my scooter?
Is this app compatible also for ES1?

Why someone have to disassembly it?

Thanks
Roberto
