The product is delay sending about 1 week as the vendor told me. But when it was sent. I received in one week.
The product look Ok. But I didn't try it yet. I just charged it. And wait for a ride. I check status of the Batt in ninebot app. It shows the batt information correctly and the ride time is decrease. It should be fine when I use it in the actual ride.
It is item that satisfies a lot of people 18650 battery contains only 20 It seems that it is not bad even if it thinks at simple retail price
I was surprised a bit, but I do not see the speed increase afterwards, but there's strength in the ramp.
