Ninebot Z10  995 Wh battery is not the smallest one around, but...  in the cold weather range of Z10 may be short for "power riders" 

Thanks to international cooperation I have obtained, customized and tested for around 1 month already very good and light fast charger - it solves the range anxiety issue really well:

  • Switchable 2.9A / 6A current for normal/fast charging -  in fast mode it offers around 330Wh/h of charging - which is 3 times faster than the original 120W charger,  
  • Low mass - with all cables and integrated charge doctor 630 grams only (which is less than original 2A charger which is 660 grams)
  • Balancing function - at the end of the charge power supply still offers 0,6A current to allow BMS to balance cells - see pictures for balancing process

Hello @Afeez Kay @stephen - please write directly to Wector  <wectorels@gmail.com>   You can mention  that You have the contact from Lukasz.   

If You will be interested in super small box for charge doctor - like I have used here - let me know - this is my design. (regular bigger universal charge doctor can be used of course - see it used on the  thread

Hello dear euc friends,

you can order the pin for ninebot z on gearbest with adapter for almost 20euros, only for the pin because it will charge at only 1.2 amp.

so with charge doctor you can help yourself out!

Me again,

for those who want a good charger:

Hi,

Since I 'm in Europe (Belgium) and didn't want to pay double import taxes (CN > US > EU), I ordered this one :

https://eunicycles.eu/en/chargers/164-smart-charger-300w-588v-nb-z10.html

Smart fast charger with some programming capabilities and display integrated
(Kingsong derivate - manual mentions kingsong ?)

Keep you posted on delivery and functioning ...

It's a nice unit, but personally I would struggle to pay £125 (plus shipping at ?) for a £40 charger delivered from Ali (and 6A if using a Wate one) albeit with an added:

Display (£10 on Ali if you really want/need it).
Facility to adjust charge cut-off (or just use your watch with a calculation of % per hour - on the Z10 a 6A charge gives around 30% battery per hour)
Ninebot specific plug (can use the original one off the old charger).

I get that this is simple, requires no soldering of the old Ninebot plug and that you need not worry about % per hour but for me it's too pricy. All people are different of course, and YMMV. Good find though :)
