I think that the heat sink is present because keeping the battery cool under load greatly improves the charge/discharge capacity. At least it’s something I’ve read about how Tesla approach it..

Have you found what the 3 cables are for, in addition to the battery connector

Hi friend . Can you advise on what battery and controllers I need for a DIY 8000watt escoot build thanks

Good cells.how many were u able to recover ?

For what reason there are this big resistors on the BMS?

For what is this three more cables on connector?

Do you have any idea were I could buy a new battery as I have the scooter but no battery?

very cool!

I have a Niu 60v 29ah battery, with the green Panasonic cells. I like to know how many amps is the BMS in my battery.??

There are some spelling errors i know, but the red/white tape is most likely "water sensitive" and will try it again with water on the white side tomorrow. It cant really be anything else that i can think of.

Thank you for this Video. Did you repaired the battery? Why the Video has a blackscreen after about 11:30?

Do you know if this battery could be removed from the plastic shell and used in another platform? Does this BMS require it to be used with an NIU scooter or will it work with any other compatible 60V controller?

In a trike battery pack get smell and battery charge sign in the screen goes brown why.

This battery have active balaced?

What happened with the video after 11.30? The music continues but it is all black.

Do you know the wire designations for the purple/white/black wires that are used for charging? I have a generic charger I’d like to use b I don’t know which wires are for what on the charging input. There’s 3 wires so that confuses me.

Do you know something about the BMS @The Battery Doctor ? I am trying to read the % of charge via BMS. To make a circuit with socket and raspberry Pi to keep it at 50% but also being able to charge it only to 80% or 90% to increase battery life but also not having to look every day for correct charging. Such a automatic device will be cool.

New sub here. Good day Sir, I have a 60v26ah niu battery pack. Is it an 17s6p? So 17sx4.2v = 71.4v is that the full charge?

Did manage to recover the battery? Did you try to charge the cells to see If battery recovered?

När ett NIU-batteri blir sämre med tiden, är det ekonomiskt lönsamt att "reparera" batteriet och byta ut vissa delar av det, och hur mycket skulle det kosta? på ett ungefär.

Hello battery doctor, I have a NIU 60v26ah battery when it is at 100% it measures 70.5v. The link of the original charger has 5 terminals, 2 are + and - the other 3 do you know what they are for? I am trying to charge with a non-original 67.2v 20a charger using only the + and - terminals and it doesn't charge, it doesn't recognize the battery, you know what I'm doing wrong?

is this battery a 17S10P? can you confirm please

Are you going to finish Video? I would love to See how you fix it

I have 2 NIU 60v 26a batteries. One charges fine and the other is too dead to charge showing only 8.2v. How can I revive the dead battery so it will charge again? This scooter is brand new so the batteries are new. They have been sitting 8 months Thank you

Where are you from Battery doctor?

So Blue color battery is not from Panasonic battery cells. It's an China battery cells, isn't it?

Undrar om kvalitén på deras batterier är anledningen till att du inte har fler videos på Niu reparationer 🤔

Hi, I am trying to recover this niu battery. The batter was verry low and I am trying to jack it up, the battery now gives around 58volts, but after the bms i measure 29,6 and it is not enough for the charger to take over and I can't get it any higher. Do you know what might be the problem? Is the bms failing?

It better last because the price is very high 14 995 SEK.

Hello, I have these batteries available for wholesale can you point me in right direction for buyers please

you measured the balance wires incorrectly, they are in the connector in a weird way and you were measuring multiple series. they are a 17s so the voltage was around 1.2v per pack. if your playing with these you should work it before posting a video as you will inspire people to take theirs apart and attempt a repair. if charged incorrectly they WILL cause damage and potential fire. I have repaired a number of these now (50+) and I am still cautious with each one.

This is like Tesla battery module lite.. just passively cooled at a much lower discharge rating.

The BMS just went to sleep. Here's how you wake it up kzfaq.info/get/bejne/m9l7d5yf1a7Rnok.html

About the charging port what are the 3 thin wires for? Thx
