How to I handle my battery best?

The battery represents roughly half of the price you paid for your NIU. So it should be maintenanced at least as well as the scooter itself.

[UPDATE: In 2018 NIU themselves published this page pretty much covering this FAQ entries content.]

Daily Use

  • Optimal charging temperature: 10 to 35°C
  • Using-temperature should not exceed -10 to 45°C
  • Do not unnecessarily keep on charging the battery when it is fully charged (Green LED lit on charger)
  • Do not completely drain the battery – try to charge at 10% at the very least.

(long term) Storing

  • Optimal storage temperature: 0 to 20°C
  • Recommended charge of 40-75%
  • Check charge-level every 2 months (e.g. put it into your NIU to get a proper readout)
  • Charge it to 100% when planning to use it again

Tips

To make sure you’re not “overloading” your battery you could use this engery-saving mains socket from Ansman (or something similar):

This automatically cuts of power when it falls below a certain (programmable) threshold, e.g. below 50 watts.

  1. Hi, I’m wondering if it’s okay to leave my scooter outside during work hours when temperatures drop to about 0 °C or 32 °F and less. Before and after work the scooter is parked in a closed garage without heating. Ambient temperature should be not too cold.

    Thanks!

  2. hello
    i have had to leave my Niu NS1 Sport unused for the last 3 weeks. I have taken out my main battery and the level was at about 55 as recommended

    However i can see from the app that my ECU battery is now at 18% – it was 100% when i left it. Will this be a problem?

    many thanks
    John

  3. You just discovered one of the major flaws on the Niu scooters. The battery is emptied within 3 weeks when not in use, mainly because of the GPS. You can make it go empty slower by disconnecting the battery before you leave. Full drainage is bad for the battery and gives us an empty scooter, the manual says it shouldn’t be below 20%, right?

    => If Niu is reading this: please come up with a smaller adapter in the charger (so I can store it IN the U) and make it usable as a trickle charger (so I can just connect it to the charger until I need to use the scooter).
