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..
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.
i just bought a second hand battery like this one. all the sells are on 4v so there good. i cut the normal + and - conector and solderd a anderson on there. this should not affect the balancing right? i also charge with a difrent charger. a anderson 4a 69.7v charger. i should be good to go right?
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?
@@TheBatteryDoctor this is 60v 29ah I have two battery niu than 60v 26ah I have one charger 60v 20ah for 16s 67,2v, I can charge the batteries with this charger without problems?
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?

@@ThatminecraftguyRotterdam In case of putting this battery in a scooter (formerly lead acid), would I need to connect these 3 cables directly from the battery to the incoming plug of the charger, while having the + and - cable go through the scooter and then end up at the charging socket?
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.
no. The customer did not want a repair but i assume NIU seller have accesses to smart functions. But if you want smart functions you might want a smart BMS. You can have 2 parallell BMS systems in most cases.
@@Batteridoktorn i habe access to the diagnosis Tool of Niu. It can read battery Status but sniffing with rs485 at 9600 baud rate I was not able to get a message by sending the same bytes as the diagnosis tool.

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
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.
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.
@@JK-nd7ez Alright, that sounds reasonable! I mean, I consider buying a slightly used NIU and sell my gas scooter, but I want to be sure that it pay off and is worth the sacifice in less range etc.
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?
With smart BMS like this they usually STOp working when voltage is to LOW and usually you need to connect it to a PC and have the right software to reset it.
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.

yes, materials do change their properties when the temperature varies. Cells might also swell in extreme cases
Have you found what the 3 cables are for, in addition to the battery connector
For what is this three more cables on connector?
So Blue color battery is not from Panasonic battery cells. It's an China battery cells, isn't it?
Panasonic is green with very few exceptions.
What happened with the video after 11.30? The music continues but it is all black.
Adobe premiere desided THEY should have "final cut" and added a black screen for a few minutes, but i will ask youtube to cut it, thank.s
In a trike battery pack get smell and battery charge sign in the screen goes brown why.
Do you have any idea were I could buy a new battery as I have the scooter but no battery?

Undrar om kvalitén på deras batterier är anledningen till att du inte har fler videos på Niu reparationer 🤔
Hoppas det!
Har en ny Niu som jag tar in batteriet från varje dag. Garantin säger 2 år, men förväntad livstid är 5 år enligt Niu.

Hi friend . Can you advise on what battery and controllers I need for a DIY 8000watt escoot build thanks
is this battery a 17S10P? can you confirm please
Yes its 17S10P. 63V nominal. very popular for the bosch 1200W motor.

It better last because the price is very high 14 995 SEK.
Yes, way too pricy given the total cost for the cells alone. But then again, that's only i Europe.
I live in Scotland could you please posibly tell me were I could buy a battery for my scooter as I bought stolen recovered

Those other 3 connectors are communication between the bms and charger. Without that communication the battery will not charge.

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?
Are those chinese batteries any good in cycle life?
About the charging port what are the 3 thin wires for? Thx
It is RS485 to communicate to the Scooter.

Did manage to recover the battery? Did you try to charge the cells to see If battery recovered?
no, the owner did not wish to have it repaired. NUI is still very new we seldom get reguests (expect for today) so maby we will make videos.
and that person is you =)

When a cell is broken thats not much of a cost factor .. a single cell cost around 5-10$$

They video ended at 11:30 but adobe premiere thought different and added a few minutes.
This is like Tesla battery module lite.. just passively cooled at a much lower discharge rating.
