Discuss the Segway Ninebot ES Kick Scooter in this Forum. Topics include the Segway-Ninebot app, hardware, street riding, and much more.
I've tried to use one as a power source, but not connected through a ninebot controller. It turned itself off briefly after a draw was put on it. I'm not sure if this was due to missing feedback from a ninebot controller, or an excessive draw, but I believe it was the former.

I am trying to use another main es battery as a secondary. Does anyone know how to connect the 4 pins from the second battery to the port on the controller board? The leads from the battery are labeled: c-(black), c+(red), rx(white), tx(yellow). The controller board port is not labeled. I have numbered the pins on the port and am hoping someone can help me get it connected. Many thanks!

Is that top pin for the discharge + or -?
If I remember correctly, I think its - but I know that on the board there are labels right next to the solder joints

I am attempting to do the same with mine. I have a 12Ah I'm adding to the front using the cage from another scooter. I have kept the charging port separate so I can use two chargers at once. My question is what exactly are the tx and rx used for? Can I run without attaching anything to them? Also, on the downtube, is the top pin + or - of the discharge pins?
I assume tx (transmit data) and rx (receive data) are for the battery to talk to the control board to let it know wattage, cell voltage, etc. If you do not connect these wires either it will flat out refuse to work, or if it does you may risk damaging something

Do you have any experience using the Es primary batteries as a secondary battery on the M365?
I’m getting ready to install two of them on my dual motor setup but I’m not sure if I need to do anything with the 4 wires in the plug. Or if I just use the +, - as you would with a regular secondary battery in parallel. The existing charger port will charge it.
I added a main Ninebot battery as a complementary battery to my M365.
You just need to connect the two batteries in parallel after the BMS, ignoring the other wires from the Ninebot battery.
You also need to install a CFW with this parameter : https://m365.botox.bz?version=DRV138&re ... ng_mode=on
Otherwise it's unusable
I'm able to do 40km with these two batteries!

Is there any benefits to doing it this way over just using the extended battery that they make for the ES ? There both the exact same spec battery. Most of the Lyft, spin, and Jump scooters found in the local auctions have the extended batteries.

And depending on what type of board you have you might not see any increase in speed as I believe that’s in the firmware. However you will feel more power and faster time getting to the top speed. ( same top speed as with 1 battery)
The benefit is when you have a ton of primary batteries but no secondary.
Have you bms (or all battery) for sale? my bms died... To view images REGISTER or LOGIN for full access.
