No matter but first my friend have to send it back to me, and when I will get it, I will be able to send it to you. let 's keep contact

A simple solution is to start the load directly to the battery output (XT60 plug), I have made an adaptor for that. I have send it to a friend that tried it today and the Z6 battery took the load immediately. 15 minutes after that he was able to load is battery by the normal way. before to send it to him, I have tested the adaptor https://www.facebook.com/smallexis/videos/1001487490049175/

When ninebot's BMS is in security, that do not allow the real voltage to be measured. So it's impossible to be sure that cells are damaged or not.

Whole original white shell for Luffy, in like new condition (see pictures below). PRICE : 120$ + shipping Sold without any screw. Please contact me for any information. -
Maybe you can go to a car or motobike station in order to ask if the could repair it for you? I think it's better to see a professionnal before to try by yourself.

Same for me, around 50km range if I go slow. For battery capacity, 995wh / 3.7 (mid voltage for a cell) / 14 (number of cells on series) / 6(number of parallel) = 3.2 Ah (capacity for one cell) Again, Ninebot (segway) didn't choose to work with the highest (and real) capacity on the market that is 3500mAh (3,5Ah) for a 18650 cells. I have seen a new cell from LG which capacity is 3600mAh (https://eu.nkon.nl/rechargeable/18650-size/lg-inr18650m36-3600mah-10a.html) So on the same space and shape, it's possible to have 3.6x6x14x3.7=1118wh

You're right and I was wrong, my error was to use a bad material to make my tests. I have bought a generic charger 58,8V 5A, and I make full load since 2 months without any problem And I have make an other test by adding the original 2A charger. The load at 7A had worked 1 hour before the BMS security turns on. I was not able to load again before to wait 24h and I was scared to have burned some BMS's component. I don't know what would happen at 6A, but I can say with a current at 5A it's safe and at 7A it's too high.

Yes I have made a mistake about Z series. First attempt at 3A was not a success but it was due to a bad charger. I have tested at 5A and the load is ok on my Z10. At 7A, after 1 hour loading, the BMS security turns on. So there is a security but it's allow to load over 2A but under 7A for a full load.

1 : use a voltmeter for polarity on the board 9 : for polarity you can see on charger (1 + and 2 -) : I have use a 12V motobike key switch (in order to turn off the buzzer, it's only a noise reduction interest). 18 : the app will not detect extra capacity, just the voltage is measured. You can let both batteries connected or not.

I have a Z10 and I don't think it's a pre-production. The BMS "protection" system is the same as the MINI PLUS or MINI PRO (can't be loaded over 2A)

Ever take care about voltage information in order to make a compare. The max output is the most important value. Anyway it's no possible to have a load with more than 2A, the BMS's "security" make a cut off if the current is over 2.1A. I have made a test at 3A, 2.5A and 2.2A. 3 years ago, an offical Ninebot document announced a fast charger for 9B1 E+, this charger never existed yet.

@jojo33 is right, I have a 3A charger that I can use on my 9B1E but my mini don't take the load with this charger. There is a "security" that causes the BMS to be cut off if the input current is greater than 2A. And it's the same for 9B1 Z series.

Last ride with my 9B1E+ and it's DIY battery https://www.relive.cc/view/rt10000327646

30 cells be careful about amper that will go from external battery to the internal one :
