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.
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..
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?
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.
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. But you did read the cell.voltages with yybms.com software? Or was it another bms you connected to the battery pack?
@@alexs6169 hello, Alex, it is glad to know that you know our NIU BMS, our BMS can compatible with NIU APP and PC software, if you are interested, please contact us freely at kellychan@yybms.com
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?
@@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?
@@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?
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
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.
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?
