Segway Mini Pro Battery Fix - UPDATE… Go ahead and push that button labeled ‘S1’ inside! 

Thanks for the video. My Segway has been down for 2 years. I cracked the battery open as instructed ( used a hammer and screwdriver to gently tap all the way around) I pressed that BUTTON and the green light started flashing. I put the battery back in and it says it full charged and its working now. Thanks again.

Thank you, thank you, thank you.🙏 I jumped the charger to the battery for a couple days and it wouldn't take anymore charge. Light on charger stayed green. Battery showed 30ish volts in terminals. I disassembled the battery and got 60v at the +&- on board, pushed the reset and bam. Green light and 60v at the terminals. Can't thank you enough!!!

Hey I have the same blinking light when plugged to the charger. Altough my circuit board is green and looks really different to yours (european model I supose?) and there seems to be no switches on the board... So any tips on that? Thaks

Do NOT avoid the temptation, PUSH THAT BUTTON, I bought my ninebot (cheap) "dead on arrival", when I pushed the button everything came back to life. It seems that this button resets the power management board, don't avoid it.

This actually worked to bring both of my Mini Pros back to life. It wasn't hard at all. I charged both of my batteries but it still didn't work. UNTIL I pushed the reset button. After I did that the green light started flashing and then went to solid green. I re-installed the battery pack and it now works perfectly. Video is a little long winded in his explanation but the information worked perfectly.

Great video. I had to rely on "jump" starting the battery pack and pressing the S1 switch to get my BMS happy again. Saved me $250 bucks for resurrecting my Ninebot S.

Just got 14 of these at auction from sams club. 10 don’t do anything if you plug the charger in. Tested the batteries some doubles are only at 1.3v others are 3.1 . Doing the forced jump wish me luck will update when done.

MY last resort, going for it. Since mine is dead, won’t charge, and the other option was to bypass battery management charging and charge batteries directly. Going to try the S1 switch first. Segway won’t respond to my emails and the replacement batteries are out of stock. Has anyone bought a replacement battery pack and if so, is there any instructions from Segway to reset battery system? Or is it just plug and play or due to out of date warranty sticker, we have to send it back anyways? I haven’t rode this Segway in a long time since purchasing it and letting it sit without charging made it worthless over time.

After I removed the battery I noticed there's a small black plastic part, about 1/2" wide and 4" long. Make sure it's out of the way and fits in the groove completely. Otherwise the battery will not make proper connection with the main board and the pro will not turn on

Today I had the problem, that my charger did not charge the battery, because it was drained too low. I just removed the batterie and connected the charger as you did, but without removing the batterie cover. I just used the 2 bigger sockets that are exposed to the outside. Just waited a few minutes until the red blinking LED on the batterie turned to green, then plugged in the charger normaly and was able to fully charge it. I think opening the batterie only makes sense, if what I described does not work any more. Than you can give the S1 button a try.

Holy Moly! This is working for a dead Segway Pro I just found for free on FB.

okay so thank you so much it is freaking worked!!!! I had this problem 2 years ago and never saw this video and threw away 5,700mah battery.

Got the ninebot for 30 bucks bought charger amazon 30 bucks, no charge,

Knowing how to take these apart is so easy it makes sense to recycle them - take the old cells out when they are tired and replace them with new ones - perhaps even of higher capacity. Just make sure you do a datasheet search on the current cells to see their discharge C rating, and meet or exceed it with the new ones.

could you tell me where to buy the charger please

Do you know where I can purchase the 4 prong charger? We lost ours and can't charge the Ninebot

Thank you.

Good to know. Is there a way to hook up a spare battery to extend your ride distance on these, or do I need to take a spare battery and hex wrench and swap them out? I'm only getting like 5 miles off road distance with knobby tires.

The battery connector if you are looking at the pack with thw connector away from you the positive is on the right neg on the left the two big ports
