Alexei from MiMod.ru has designed this essential application to know the status of each cell of the battery of our Mini.
Do not forget to reward his wonderful work with a PayPal donation: https://www.paypal.me/mimod
The installation is done on an Android device, allowing "unknown sources", the application is safe. Then you just have to connect your Mini with Bluetooth.
Battery & Charger
The official battery has a flashing LED on the inside and a seal encircling the entire outline of the battery, 4-pin, she 4300mAh
The 100% load is lorque the charger turns green and the bars flash
When the bars do not flash but are all on there about 90-95% (it's safe for your battery life)
When you load the MINI, the bars are all full, but they do not flashing, battery is charging around 85/90%.
This is a good charge level, to extend a Lithium Ion battery life
Of course, I also preferred to be fully loaded at 100% when the bars are flashing.
What I don't recommend is to charge the battery "hot", just after a ride, is not very good for the health of cells. I usually wait a half hour before recharging, the battery is "cold".
It's like a marshmallow, is deformed by taking in hand then it took to its original form, you can take a look, in app, the "remaining capacity", you will see that the level of battery increases when the mini is stationary.
SMALLEXIS is an active member in the forum URBAN360 Forum, you can also meet him in the ELECTRICUNICYCLE.ORG forum, it is an assembly expert batteries and BMS, a true genius !
He therefore remove the battery from Xiaomi MINI, and explains some interesting points.
"The first step is to open the existing battery to see how it is made. But this time we must face the facts, NINEBOT set the bar high with a fairly complex BMS and industrial welds Points directly to the BMS.
So it is almost impossible to regain BMS for assembling the new cells. Anyway I do not venture me ........... sniff!
The grid that we can see is a protective grid, no ventilation because it is sealed with silicone.
I have shit to open the ABS case, but at least I saw what I wanted.
We better understand the presence on the implementation of the bookmark "BMS FIRMWARE VERSION" because it's a little more than a BMS is used.
I doubt that the Chinese copies battery can compete, so they will never be recognized by the app.
An original product NINEBOT must be compatible since it must use the same BMS on all mini version (single cell capacity change).
I have not yet closed the beast but it should be fine. I just have to find how to replace the silicone seal that left in tatters. "
Muchissima Gracias Amigo !

Small Vehicles Powered by Lithium Batteries – Passenger Provisions
Updated 19 February 2016
This notice is in response to questions raised by operators regarding the acceptability of small vehicles that are powered by lithium ion batteries in passenger checked and/or carry-on baggage. There have been reports of these small vehicles being sold at airports in airside shops, as well as being available in many cities, particularly in Asia.
Some examples of these small lithium battery-powered vehicles are: airwheel, solowheel, hoverboard, mini-segway, balance wheel.

Never, never, never !
A battery that is not original will bring you some problems such as the inability to properly use the application.
Indeed the application Ninebot does not recognize the battery, you will not know the information about your battery.

NINEBOT MINI (Xiaomi) battery hack (now I can put in parallel my external battery)
SOURCE FROM @SMALLEXIS TOPIC ON EUC FORUM
Our frenchy Genius SMALLEXIS did it !
Like a rainbow after a rainy day,
Like a divine sunshine between tow heavy grey clouds, rayon de soleil....
SMALLEXIS DID IT
ALLELUIA - hallelujah....
" Here the challenge is to be able to put 15 cells (for just a 190Wh) following the format of the cover (yeah otherwise there is no point) So there are two sets of six cells glued offset (to make it more rigid) and at the end, there are 3 cells (glued in triangle shape, for the same reasons) The packaging is not very nice either regular because I have recycled old packaging already used."
" I make a hole (with a soldering iron) to bring out the power plug, the charging socket, it is accessible from the top of the zip. The goal is to have easy access to the charging socket, without having to remove the battery or remove the cover (even if it's quick and easy)."
"Once this little world inside the pouch closes perfectly. And may the soldering iron is hot, I make a GX12 -4P to LEMO adapter in order to use this external battery or on the mini or the 9B1."
"The battery creates a slight imbalance toward the back but nothing too bad. The cover fits perfectly on the mini, without causing any problem."
"And finally, without this being the initial target, this package also attaches very easily on the wrist of the 9B1 (though aesthetically it's less that)."
