Watch out, the mini lite battery has the connector reversed. Look at the small black pins to figure out the correct polarity.

Thank you so much, this made my daughter so happy again, she loves her ninebot.

Great video, but I can save you some work. DONT cut the cord! Look closely at the end of the charger barrel (take a photo if you need to). Two holes are marked #1 & #2. #1 is hot, #2 is negative. The charger puts out 60vdc. FIRST - TURN OFF THE CHARGER! Find two very small finishing nails - and bend the last 1/4" of the nails at about a 30-40 degree angle. Push them into #1 and #2 being VERY careful that the nails do not touch. Now just align the nails so you can get them into the left and right battery holes (like in the video). Turn the charger on and you'll get an immediate red light on your charger pack. Within 3 mins, my battery pack started flashing red. Once that happened, I put it back together and was good to go!

Roee Bloch and Dave Garia and Rashid Ahmad have videos that, when combined, helped me get a red charging light on a ninebot s plus to charge without cutting the wire. I don't know if it has worked yet as I will let it charge for a half hour before putting it back together. I do think it is important to unplug both wire sets like Roee says to do before proceeding too far. Thank you all three for being so awesome to take your time to show people this, it is people like you that keep my spirit alive and from falling into deep depression from the evil people do to each other!

Thank you Johnny! I haven't tried it yet but I will and I really appreciate how cool you are!

I did two today. Works exactly as described. Thanks!

🤣🤣🤣 that bit when your mate plugged the charger in and you were holding it!!!

So amazing followed this instructive video and got my Segway charging in no time. Thanks so much for all your help. Your the best,

what a great video. Will this also work for segway batteries that seem to charge but then upon turning them on they don't hold the charge at all and immediately deplete/die?

Worked like a charm! Thank you🎉

❤️❤️❤️ so glad i found this vid. Will be trying soon.

I'm so happy. This really works. Thanks

Man good informative video but I was laughing 😂 at the same time when you almost got shock there, going back to the Segway I bought my son the ninebot pro and the Hoover board is completely dead, I’m going to try the same thing you did, thank you

Worked for me! I have a variable benchtop power supply - I set it at 59.5 volts and 2 amps (what the Segway power brick is rated at) and used banana plugs to connect to the battery pack. I watched it draw starting at 20 watts and slowly climb to 105 watts, so I knew it was charging. Waited around 30 minutes then connected the charger. Took a full charge and now works! I have seen third party chargers that are 55 volts up to 63 volts, so it looks like the battery pack is pretty forgiving on charge voltage.

It worked!! Thank you so much!!!!

Yeah I took my Segway back apart to give it a deep clean and sure enough a year later and I have no put it back together when I tired the first time those metal brackets that screw in make the wheel on the right side rub against the frame but I’m sure it’s something I missed anyways is there anyway you can do a tear down video :) would love to see one not many tear down videos done on KZfaq! Or is there any? Love your content new subscriber!

Me: not knowing wtf I’m doing Also me: definitely not calling an electrician

Great video. Be mindful that the charging brick can hold a little juice for a few seconds after killing power so keep those leads apart while disconnecting from battery.

Thank you for this video. It helped me recover my battery. I was about to cut my charger cord, but I decided to play with my volt meter 1st trying to figure out which of the 4 connectors on the regular charging end was wired to the positive female banana connector and which was wired to the negative female banana connector. So I had my volt meter in continuity mode and tested each of the four posts on the battery with each of the two female banana receptacles. I was surprised that none of them showed continuity. BUT then I noticed that the LED on the bottom of the battery was blinking red. It had previously been dark. So I just connected the charger and now the charger brick has a solid red light and the LED on the bottom of the battery is blinking red. It had blinked green a couple of times when I first started this reply and within a few minutes, it is now just blinking red. Maybe testing the continuity between the four posts on the battery's charging connector and the two banana receptacles reset something because now it appears to be charging and I did not have to cut my charging cable.

I opened my battery pack and all the individual cells are 4.16 to 4.2v. The output from the main terminals is 20.8v. Input from the charger is 42v. Charger has green solid led. Led is off on the battery pack.

A Big Thanks.

My Segway S-Plus it dead ad well. My issue has two problems. 1st, my power button started not working after the unit was exposed to rain water. It appeared to survive, but the following day, it began to have erratic power symptoms. The charger had no effect, and there was no power down option in the app. I didn't want the unit to fully duscharge the batteries and / or continue shirting out with what appeared to be now water contamination. This appears yo be an issue to not have a user accessible master battery disconnect switch. I also felt heat coming from the hump, where the batteries are located. So, I decided to dismantle the unit to try to fully disconnect the batteries to avoid a fire hazard issue. I eventually took off the bottom panel and disconnected a main battery lead, but that didn't stop the unit from emanating heat from the hump. I had to then continue dismantalling the unit fully to remove the hump, revealing the battery array. There was where I found the source of heat coming from a circuit board with no disconnectable battery wires. This was also where the moisture contaminated a circuit board poorly located at the very bottom, water resting point inside the battery hump compartment. I was able, then to disconnect all battery connections going to the circuit board, eventually stopping the power from reaching the shorted out board and causing heat upwards of 192 degrees. I plan on suing segway to replace the unit because the S-plus is supposed to be water resistant. To include poorly designed circuits with no master battery disconnect posing fire hazards to the consumer in their home, garage, or car where the fsiled unit may be stored. Segway blew me off, claiming not to address water ingress issues. I will update you with the progress of my pursuits. The unit is excellent, and I purchased an identical replacement already because it has become an integral part of my business

Gracias, acomode una gracia a tu video, Dios te bendiga más

thanks - jesteś najlepszy

A note for anyone with the same issue on.a MiniLite. The power port (might call it a d-shape or trapezoid) is inverted... Positive and negative therefore switched. Looking at the charger the center post is positive and outer barrel is negative. But the rest of the procedure should be the same. I was getting four quick red blinks and one slightly longer when plugging in AC. But light stayed green. Once I rigged up power directly to battery I got just a red light on charger and it is warm now while charging. Hopefully works out.

Hi, thanks for your video. I did everything the same, but my charger always turned on green, it doesn't change color. What can I do?

Have a ninebot S-Plus with the same issue, don’t have the motivation to fix it, anyone know where I could sell it?

👍👍👍

It worked! This fix with the s-plus is very easy when you know what to do! No need to remove battery nor cut the wire.

Mr.rashid if I send u my ninebot s max battery the 432wh it's blinking red won't charge.woild u be able to fix it? I'm in desperate need as it has 30miles and plenty of speed+tork for my ninebot s. It just died on me 3weeks ago please 🙏

Revived my battery with your method… battery started flashing green, charger went from red to green after about 20 mins. Now my charger stays fully green (indicating the battery is full, but it’s far from full) when I plug it back up the normal charging method. After a couple of hours charger is still fully green and battery still flashes green but battery isn’t taking any more charge. What gives?

So I put my Segway into storage around 2020 and the battery drained. I tried charging now in 2023 and the board is dead completely. I just opened up the battery and pressed the S1 button that others have mentioned worked but nothing happened for me? Any suggestions to bring it back to life? It did allow it to get a single red blink when attaching the charge cable but nothing after that so far.

I have the same segway and it rides perfectly but for some reason it keeps beeping and I don’t know why.

my son drove into the water, the segway was all wet, I dried it, when I turn it on it does not work, unscrewed the battery, it works and charges, but when you plug it in, it does not work, any ideas how to restore it?

Thank you so much I'm ali from Uganda I'm losing my charger so I need a new charger but I don't know where I can get it please help me my bro

Hello, What is the name of the app for this scooter?

Instructions unclear blew my battery and face off and i am not alive any longer. Stuck in purgatory now but i sent this thru a median who i had to bug for two weeks STRAIGHT (kus what else can i do )thanks.

Hi! I have done this and it worked perfectly. But after a day, I tried to charge it again. It said it was charging, but when u took it off it was beeping all the time and showing the same 10% battery percentage. Tried it again, same thing. Does any one of you know what could be wrong? I really don’t want to spend 300€ on a battery replacement. Thank you.

I need your help 😢 the light is green when i took the battery out but when i connect it it flash for half a second and it turn off and the light is greeen so its not dead

Anybody had trouble with the light not coming on steering wheel if so is there a resolution?

Hello, how can I do that on a Ninebot S Plus? Thanks

My charger keeps turn green , and battery led also turn green after 1 second turn red. Does it mean the battery is defective?

My ninebot one is doing this and I’m trying to do cpr now

What if the charger doesnt turn red when I do this

You dont have to cut wires. Im an electrician. Use "jumper" wires right out of the connector and a multimeter to find the positive if red isnt obvious.

my charger light flashes both green and red What does it mean?

I have 4 for sale with the battery problem if anyone is interested

My minipro do not turn on... any idea?

I had my battery charged up like you did after waiting 20 minutes, but after I plugged it in to the original port, the charger shows green light and the battery shows red light beeping in 1 second interval. What should I do ?

The battery wasn’t dead when It started doing this

Hi I have 4 of these anyone close to Manchester can sort them please?

Hired a licensed master electrician so you don't electrocute yourself!!! If you just want to get rid of your dead Ninebot, let me know

you do not have to cut the cord on your charging unit. Instead use a pair of cords from a multimeter. the plugs fit perfect on the battery. then wirenut a size 18 guage wire to the tips of each cord at the pointed tips. red on the left and black to the right. then push the striped end of the wires into the proper holes on the charger tip. then begin charging. if the charger light starts blinking red then green, just give it time and it will eventually blink red which is the charging mode. once it goes green unplug everything and plug the charger into the regular charging port to complete the charge
