NIU Electric Scooter 60V 26Ah Battery Repair, issue appears after charging it at high temperatures

[@tszonline6159]

Very nice one! They used better screws in the GTS battery than in n1s... but the case is much come complicated to open.

[@ruthmoreton6975]

Thank you. My main ride right now is a GTS-Pro ( dual battery ). It's fine right now but I collect videos on how to fix it for when it does break.

[@jb9282]

🎉 thx ! Die you recharge disbalance cells with you Labor Power 60v / 2A ? After you did use again a NIU charger ? PS - you don’t need to open for measurements - on the long connector you can do it directly each cell .😊

[@Gehtdichnichtsan583]

Is there a way to wake up the bms or is it necessary to wake up the bms?

[@jonvaldezcars]

Random question. Do these battery packs have the output enabled by default? If i wanted to use the power output for something else, is it possible or do I have to communicate with the BMS somehow to make it turn on?

[@freshmaker5]

What do the wires coming out of the battery do? The two thick wires go to the controller but what do the three thin wires do and what do you hook them to?

[@01ai01]

Awesome video! Found this because I was curious if these are repairable.

[@cyrilleancelot8167]

Wahou, so nice video. Can you share the list of devices you use to repair it? I have a niu since more than 4 years and the battery is over (can only do 20km with a full charge). I would like to change the cells but need to find the tool you are using (such as the solder devices etc…). Can you help please?

[@joeKisonue]

U need a battery spot welder, nickle strip or grid,cell insulator stickers,

[@raulenchautegui4749]

How can we contact you for this type of repair? In getting the same error after accidentally touching the main +/- terminals.

[@mjr2567]

Thanks for the video. I recently got a Niu Nqi GTS Pro which has 60v 35Ah batteries, I believe. One of them takes longer to charge and discharges faster. The last two days after charging to 80%, when I wanted to charge higher, first the battery would not charge with the splitter and then when slightly more charged would not charge by itself. Today it shows 5 lights flashing... In your opinion, does this means it has faulty cells?

[@ChaseMavrick]

What is the name of that analyzer?

[@fotoamgamgfoto3695]

is it a 17S20P pack? hmm no 17S10P as they are upside down in 10P blocks?

[@vsl5917]

Hello friend, You should see the new cells put at the same voltage as the others, because otherwise they will always be unbalanced with respect to the others

[@EVCustoms]

Yes for sure, i have do that my friend... you can see them balanced at the end if video...

[@DKLVE]

@@EVCustoms yes I noticed the same thing the other packs were at 4.1V and the new one at 3.7. I really appreciate a fine job like this one. I suppose the fix was cheaper than a New battery. Congrats on the fix🦾

[@HugoVarandas]

My battery generated an error 154 in the scooter because of the same symptom you showed at 12:26 ... The dealer told me that they did a balancing of cells to fix it. Why did this happen? do you have any idea? To charge, I use a smart plug and turn off the fast charger when it falls short of 100w of consumption (to avoid overcharging the battery). Maybe my smart plug is generating this condition (don't let the battery equalize the tension between cells)?

[@ebikebatteryrepair]

you put new cells with 2.5ah but other old cells in the pack not 2.5 because they old maybe 2ah left in them.dont you think that will cost unbalance or over charging problem in the future ?

[@EVCustoms]

If we put new with old ones, at the end we must balance the batteries at the full voltage state 4.2V, to make it work properly.

[@alfredyap8397]

The plug port got 2 big pin and 3 small pin. Is that 3 small pin for charging? Thanks

[@bulja333]

Hello My battery has been drained to zero. I charged up to 3.2 volts, maybe the diagnostic sheet will start the BMS Or I need to buy a new BMS Thank you very much for the answer.

Buenas,tengo un patinete NIU KQi3 Sport que no se cargó en 1 año y no se si puedo recuperar la batería y si no es así que batería le puedo poner económica que no sea la original y que sea de calidad?,creo que es de 48V y 7,8Ah y con interfaz creo XT60, agradezco enormemente la ayuda!

[@oogabooga4006]

Can I use one of these packs in a different scooter model by opening it up and using a different connector? Current scooter is a dual motor 60V, current battery is 67.2V. Could this battery be repurposed to work with a GX16-3 charger?

[@kerekreatif]

Brother may i ask, can we upgrade the battery used same tipe but with a bigger mAh? Thankyou

[@EVCustoms]

Yes you can do that..

[@antolinbr]

Do you have to wake up the bms after swapping cells? If I want to swap all old cells due to wear is this procedure working?

[@EVCustoms]

If your cells have same voltages balancing no needed, yes if you change them successfully everything will be fine.

[@antolinbr]

@@EVCustoms thanks for your response. Subscribed now onwards 🥰.

[@peterpulp]

Hello I am Greek to!! In this battery can we add more cells parallel to extend range or it will not work?

[@EVCustoms]

Hello Petros.. Of course you can do that.. the only thing you must manege is to find space..

[@peterpulp]

Thanks for your reply!! If we talk for 10 or 15 amps more I think the existing space is enough. If you agree!!

[@EVCustoms]

@@peterpulp If tou find 3.5Ah 18650 cells... yes you can make 35Ah battery, extra 9Ah.

Thank you very much!!

[@mareklimanowski687]

This BMS don,t need reset or unlock after repair ?

[@channyroeun3122]

Which 18650 battery cell specification require for this replacement? Example: 2700nAh, 3.6V, maximune discharge 6A?

[@ericklein5097]

Yep I kept watching and its 6:07

[@tszonline6159]

Did you know that the BMS was OK beforehand? I first would have checked the BMS on a different battery ... did you diagnose before? I do that using a YY BMS.. (h1 did not get any data as voltage was too low).

[@EVCustoms]

No i didn't check BMS because this issue is common on new battery packs, with Chinese EVE batteries...

[@e-autoauctionsdirectanycar9783]

​@EVCustoms Won't such a problem to the other cells?

​@@e-autoauctionsdirectanycar9783are calling individual 18650"cell" or each stack?

Nice video, maybe you can answer, because i'm not good in electronic, i have an NGT 125 with 2 60V 35AH batteries, i think like DMS are dead after charging problem, my question is, can i put a 60V 26AH battery DMS on 60V 35AH battery ? Regards

[@jackjone12221]

yes you can

[@dotternetta]

At heavy use my batteries show 45 degrees C. I watched the video, but what excactly was broken?

[@EVCustoms]

At 45 degrees temperature the charging is problem... can damage one cell and this one cell will discharge the other parallel cells... you will see unbalanced cells.

[@dotternetta]

@@EVCustoms Hmm..but I need the time to recharge to get back home. Does it matter if I fast charge or slow charge?

[@EVCustoms]

@@dotternetta When you say fast charge? how many amps?

[@dotternetta]

@@EVCustoms 12 Amps, 2 batteries simultaneously, with Niu splitter, I dont know what is does, but both batteries charge at the same time.

Better let them cool down, you can open the saddle and foot floor to let them cool down faster.

How do you take that battery out of sleep mode?

[@slookify]

Hi, what can I do if I left the battery connected for a week. Now one battery is at 0%, and I can not load it. Can I use an external power supply with higher voltage to bring it back? Can we disbale the ECU, just to load the battery. NIU seems to block it

[@jackjone12221]

Hi, you need to use the small charger (NQi Sport) to wake it up because it is in undervoltage protection state now and the big charger couldn't wake it up.
