My Ninebot One Z10 does not charge: what to do?
Users who ordered their Ninebot One Z6 or Z10 or have not used the electric unicycle for a long time often run into problems. It happens that the new electric unicycle does not turn on, and the charger indicator will remain green after charging and turning on. If you are faced with a similar situation, do not panic. The problem may not be very serious.
Most likely, the device's battery automatically went into a deep sleep state in order to prevent discharge due to prolonged downtime. Fortunately, the battery can be quite easily reactivated.
What is the cause of the problem?
The fact is that the gadget continues to consume a little charge even when it is off. Energy consumption in such a state is negligible, but during long-term storage without switching on and recharging it can completely discharge a 100% charged battery. Moreover, lithium-ion batteries, which are used for autonomous power supply of the electric unicycle , do not like to stay in a strong discharge. A voltage drop below a certain threshold changes the chemical properties of the battery and adversely affects its capacity - it begins to discharge faster.
In order to prevent maximum discharge, most batteries are equipped with a BMS protection system (Battery Management System), which will reduce any residual consumption from a certain threshold. When the protection system starts up, the device can no longer be turned on simply by using a special button: it must be connected to its charger and wait until the voltage reaches the threshold value.
Some of the Ninebot One Z6 and Z10 do not cope with this “waking up” battery parameter. Stored for several months, they are discharged, but not activated, as follows, after reaching the desired level of charge.
How to start the electric unicycle ?
In fact, this is not a new problem. Owners of some of the early models of the Ninebot series, including the One S2, have already encountered the similar behavior of the device's battery, because the solution was found quite a long time ago..
The battery can be put into working condition as follows: temporarily disconnect the battery from the gadget ‘s motherboard, recharge it, and then reconnect after the required voltage has been reached. This will disable the lock and restart the device.
In order to perform these actions, you need to remove the cover on the left side of the gadget using a regular cap key of the desired size. You will find several connectors for convenience marked with white and yellow. White connectors are designed to charge the battery, yellow - to power the device from the battery.
To restart the electric unicycle , follow these steps:
• Connect the charger to the network (green light).
• Disconnect all white connectors.
• Disconnect all yellow connectors (as in our image).
• Connect the three white plugs.
• Hold the start button down for ten seconds (to remove residual energy that may remain in the capacitors).
• Connect the charger to the gadget .

The green light should flash or change to red, which indicates the charging process. Allow the electric unicycle to charge for several hours, preferably until the charger indicator turns green. Then plug in the yellow plug and activate it via smartphone.
In order to constantly monitor the work of your electric unicycle , take the opportunity to install the firmware update offered by the Ninebot application. One of its functions is to fix the above problem. And this means that by connecting the application to the electric unicycles released recently, you will not encounter a similar situation even with a long device downtime.
