Using the battery in temperatures outside of this range, may lead to long-term damage.When not using the scooter for a longer period of time, you should disconnect the battery from the scooter and keep it in a cool and dry place. We recommend keeping the battery level at around 50%. Do not cover the battery with anything and keep it away from all kinds of heat sources to avoid damage.

You can charge your scooter in a normal external outlet.  You can also take the battery out and charge it in a normal power outlet.

Can I charge the scooter in a car charging station?

​How do batteries in the NGT discharge?

The NQi GT batteries have a dual battery discharge system which ensures you maximize your battery usage. In case one battery has more charge than the other, the scooter will draw more power from the one with the higher power level. The batteries should have less than 15% difference for you to be able to drive the Sport mode and reach the 70 km/h speed.

How long does it take to charge my NIU?

The charging time depends on the NIU model you have.
M series: 6 hours
N series: 6 hours
U series: 4 hours
M+ series: 9 hours
NGT series: 4 hours

What is the life cycle of the battery?

After 600-800 charging cycles, the battery still has 80% of its capacity left. In total, the battery can last for about 5 years. This can vary depending on the general care and use of the battery.

​Can I get a fast charger for my scooter?

The fast charger is available for the NQi GT and NQi Pro models. All other models do not support the fast charger.

​Can I drive using one battery only and charge the other?

Yes, you can still drive your scooter with only one battery while charging the other. The highest driving mode won't be available to use though if only 1 battery is connected.

​Battery level

Battery Health Score and Level of Battery
Battery level at 15% or more (+1)
Charging your battery when its level is higher than 15% is a good habit to adopt. You can even gain +1 at the Battery Health Score if you do it 10 times in a row.
Battery level at 40% or more (+1)
Charging your battery often is the best habit you should have! This is also the best way to improve your Battery Health Score. It will gain 1 point if you are recharging 5 times in a row, a battery with a level higher than 40%!
Examples of good charging habits
If you have very good charging habits, your Health Score is impacted this way depending on charging sequences:
1 : -0.1
2 : -0.1
3 : -0.1
4 : -0.1
5 : -0.1 + 1 = +0.9
6: -0.1
7 : -0.1
8 : -0.1
9 : -0.1
10 : -0.1 + 1 = +0.9
Therefore, assuming your score was 99.8 when you bought your NIU electric scooter, after 10 Battery Cycles you did not lose any points and rather gain 1.8! Your Battery Health Score is now 100.

​Battery gets down to 0%

If your scooter battery gets down to 0% The BMS which is the battery management system will go into the sleep state which means the normal wall charger that you would use will no longer properly charge the battery.
Solution
You could potentially leave it plugged in for 8,10,12 hours and when you pop the thing off of there the battery is still showing that it's dead because you have taken the battery down so far that it's beyond its ability to charge back up.

​Signs that you should not ignore for your battery

When the indicator Button is pressed, the Indicator will light up to show the percentage of the battery. The indicator has 5 sections. Each presents 20% of the battery level.
•If the battery leveI is less than 20%, the Indicator will flash 3 times.
•When charging, the indicator will flash to show the charging progress. They wiII stop flashing when the battery is fully charged.
•If all 5 sections flash, it means the battery has fault. Please contact your dealer for consultation.

​What are the donts in my battery?

• The battery should be used at temperatures of 10 °C to 45°C.
• Do not expose to water, beverages, or corrosive liquids.
• Keep away from the heat source, open fire, inflammable and explosive gases, and liquids.

Alarm (3)

You can easily change the alarm sensitivity on your scooter with your key. Long press the middle red button on your key until you hear your scooter beep. Don't let go of the red button; you will hear more beeps. The faster the beeps, the more sensitive the alarm is set. Let go of the red button when you reached the sensitivity you want.
