Ninebot ES2 range.

[BlastaMasta]

Hi, I just bought ES2 kickscooter, and although it is advertised to have a range of 15 miles, mine after going for about 5 miles was left with 30% battery...

Although I had my both front and back light as well as under deck light's turned on and riding in sport mode on mostly flat terrain I feel a little bit unimpressed by it's performance, or maybe my battery is defective?

How can I tell if the later is the case? are there any telltale signs that the battery is not performing as it should be?

Also I noticed sometimes it disengages cruise mode by itself, are there any sensors that turn's it off? Or could it be that there is a loose connection (or wire).

I am interested how does other people Es2 perform.
