Using Hobby Charge Doctor on my NINEBOT Xiaomi MINI

Recommended Posts

I get use to control my 9B1 battery level with the famous "HOBBY CHARGE DOCTOR" (Many thanks to Hobby for this wonder :)) and I would like to do the same with my 9B mini (Xiaomi version). As 9B mini's load jack is different from 9B1's lemo jack :( (still 4 pins but not the same shape & system. I imagine the plug of mini pro version is the same as Xiaomi version), I have to add lemo jack on 9B mini charger.

I choose to cut wire close to the charging plug in order to weld a LEMO female plug (picture 1). And on the wire I weld a LEMO male plug (picture 2). It's always the same polarity (as 9B1's one) with pin 1 for the + and pin 2 for the -. Finally, I have an adapter that can load directly my 9B mini (picture 3) or by inserting Charge Doctor (picture 4).

Now I can check the battery status of my 9B mini (pictures 5 & 6) and I can also use my 9B1 charger to load (faster than 9B mini charger).

9B mini charger is "only" a 70W that give 1,1A max. Compare to 9B1 charger that is a 120W that give 2 A, I can reduce loading time by half.

Thank you for information. As a soon-to-be owner of Mini Pro I was wondering if I could use same charger to both One and Mini. Already was eyeballing the lemo-plug.

But I am still not sure if Mini pro charger have the same amperage as ninebot one's... We'll see... Hope to get my mini pro soon. Mine is being delayed...

I paid for mini pro as a preorder from a seller here in Norway. But the whole batch is being delayed. Not desperate though... And my wife is getting better at riding the 9b1 in the meantime.

Yes I have seen that mini Pro charger is a 120W and battery capacity is 310Wh. Xiaomi mini charger is a 70W and battery capacity is 236Wh.
