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
