Error 21❗Ninebot MaxG30 BMS replacement Ninebot MaxG30 BMS Tausch Ninebot MaxG30 Fehler 21 MaxG30D

[@PatrickMobileHomes]

I flashed my BMS and now it wont blink blue again and the scooter wont turn on. I have reset the BMS by clicking and holding the little reset button on the BMS and it blinks red a couple times then a longer red light and then goes off. Have you ever seen this or fixed it? My controller and dash are working and fine but the battery won't power back on since I flashed it.

Hello, my bms is not charging, I followed all the. Tutorial but it does not charge, connect each cable in its place, the battery voltage is under 25 volts, the 10 cells, could that be the problem?

[@easyryder2855]

Hello from Germany, I will change my bms from my ninebot f40d. The new bms has the connectors B+, B10,B9,...,B1. Is this the same way to connect, as on the old bms.(B+,...,B-)? Thanks for your help

I have the error 21 problem on my scooter l, I changed the battery all together and the error still shows up. Do I need to change the motherboard in the scooter?

[@G30MaxForce]

Check the connection cabel between your bms and controller. Maybe it is not making contact. No need to change controller!

[@womwom1814]

I see a bit of corrosion and spacing on the controller bms jst port, I tried pushing the wire and the port to contact the controller board if there was any spacing, but I am still getting the error, are there any other things to try?

[@G30MaxForce]

That corrosion could be your problem...I will suggest to take the controller out and clean that port with Contact Cleaner. If still doesn't work...try another Controller.

Hi i have problem when i go full throttle it turns off and comes back on after a few seconds can u post the link to this bms pls or is there another way as my only problem is the full throttle knock off everything else is fine

[@gassinit6783]

I’m having the same problem please tell me how and if you fixed it

[@G30MaxForce]

It is the bms or the battery. You have to check the voltage from BMS and battery with a Multimeter to be sure if you need a new bms or a battery repair!

[@Jacksteelmachines]

I recently bought a G30 to fix for my girlfriend. The 'problem' was the internal charger that was fucked... at least they said this. After quite some testing , i came to the conclusion that the input port of the bms is broken ? deffective chip? i don't know... when i hook it up to the outgoing power cable (to controller) i can fully charge the battery... the led light blinks red , and when it's full it's stable non blinking blue... My question is , is the entire bms ready for the garbage can? or can i fix this little chip?:p Second can i just make a connection to a plug , and charge it with an external 42volt charger? ( connected with the Fat outgoing wires to the controller) The thin wires do nothing when connected.... I've read alot about not being a good way to charge it.. because it's not balanced charging.... But here on the forum i've read that the bms balances when the current goes out , and not in?.... is this correct?.. The bms does it's job , and also the communication to the controller and display works... All help / advice is welcome! THaaaaanks!

[@G30MaxForce]

Hello, First... ✔️ Never charge the battery through the discharge port! ( those thick wires thru controller) Second.... I don't think that your BMS is Broken. Just trow away that internal charger and buy an external one! And than Follow my video on this link below: kzbin.info/www/bejne/pZiznmmPiJyBZ5o Try this before messing with the BMS. If it doesn't work you may have to messing with the BMS! I recomand not trying to change the chip ( until if you know what are doing ) in order NOT to lose time for nothing. You can just buy a new bms on Ali. Also, if you wanna change that BMS you can let there, the balance old wires. NOT need to desolder them like I did. Only desolder the wires that are solder on BMS. This way will be more efficient! Thanks for watching and let us know what you did! 👋

[@Jacksteelmachines]

@@G30MaxForce why not? it seems like the bms is accepting it ? the light blinks red and when full stays solid blue ... you wrote in the movie is the 'C+ not working solder it to D+) wich is the output to controller?.. :)

[@G30MaxForce]

@@Jacksteelmachines I wrote that C+ should be connected directly to the battery WHERE B+ is connected... NOT B+ ( discharge ) on BMS. And also C- should be still connected to BMS. I can't tell you that what you did is ok... Do what you want 🙂 but be careful! Have a nice day!

[@G30MaxForce]

And when fully charged, it should blink blue, not constantly blue! Also under discharge it should be blinking blue faster! So make sure it does that!

[@Jacksteelmachines]

@@G30MaxForce what u think the solid blue light means? i'm getting a bms in tomorrow i guess i should change it for sure! :)

[@whosthat133]

i did change controller for new one but it doesnt charge and got code 21 error also can see battery bars

[@G30MaxForce]

1. I think that you forgot to connect the 4 small wires from BMS to controller. Look at min 17:16. So...check the connections again. 2. If you use a 48v mod ( 12v battery ) you need to flash the scooter again... " Don't show error level 2 3. Give me your e.mail ...we can talk live so I can take a look to you scooter. 4. Why did you changed Controller? 5. You BMS is dead. Thx.

[@alexw12]

I do not see battery bar and I have error code 21 the bms on scooter hacking app is 0.0.0 help

First check the connection between battery and controller. If is all ok...you need to replace the BMS.

All problem started after cable burn and scotter turned of in high speed. I fixed all cables but still some problems. I can also pay a little for your time and help. If we do videocall.
