@@hifirulezzz How many volts should it be so that I can charge it with a factory charger? At the moment, I measure 3.7 Volts in all five places, but the battery and the charger also indicate red. The main connector of the battery is 26 volts. The battery is 3 years old, I don't think the cell is bad. Thanks. (google translator)
@@hifirulezzz Everything is at 3.6V, but still not good. :( For the Xiaomi drone battery, I pulled that white cable and it was fine. In this case, is it possible to restart BSM somehow? It would be nice if there was a trick to this, I don't want to solder so much to take it all apart. :( Maybe I should wait a day for it to normalize?
@@hifirulezzz if i correct understand you, If you need a lower voltage, do you use a smaller number of cells, for this purpose additional contacts are soldered in the series connection, for example, not only for 10 cells, but also for 9 and 8?

Thank you so much, saved me a lot of money
where do you buy this case and bms for this battery? My battery has epoxy over the battery terminals
That is original batteries
Mine too. Samsung cells, 2021.
I have two that have no lights and wont charge.. any ideas?
I opened mine up found 2 lose springs in it. It had always shown fully charged but would run the leaf blower
hi i have two bli20 dead and i want to know what is your generator ?
Amazon. Adjustable power supply.
please tell me what the middle contacts are responsible for, I want to connect another battery
I do not think you should open a battery if you asking this question, sorry. It is just dangerous.
@@hifirulezzz He asked it on 3 other videos.. one of the videos even tells you that they aren't even connected lol yet he still asked
Thank you for a nice video!
Helló.
Hány volt kell cellánként, hogy lehető legyen eredeti töltővel tölteni? Az én celláim jelenleg 0,5V. :/

@@Kajafun1 3.6V was enough to make BMS recognize cells and start to work smoothly. 3.7V may be a bit high

@@hifirulezzz It works! You have to reach 3.6 volts in several parts, as you showed in the video. Thanks!
what purpose of the middle two contacts of battery?
i can not undarstand
Battery is 40V. There is no any element which can do it as a single element. So, smaller voltage is elements are connected sequentially.

Wait, what exactly was the problem... I'm confused 😮
Cells too low to communicate with charger
You never said if the battery worked again or not just that it took a charge
It is working for a year now with no more problems.
Still work with no issues...
Is the battery still working or did it go back into fault
It is still work fine. I was watching electrical vehicle repairs since then and they technically do the same to balance the batteries.
How long did each cell take to charge ? I have 3 batteries also
They are 9amp
@@markbaptist5566 I did not measure, but a few hours
Still work with no issues...
