    the cell was actually taken out of a faulty BMS pack. which was a young action that produced a tester. Of the old cells, 2 were only 1700 mAh

    Who said it was cheap? By the way, the cell is the same as the one used in the factory, only much younger. 1707544303 I drained the cells to 2.97v. I put it back in its place and charged it with its own charger via its bms. The test will be today. 4.15v charging stopped.

    that's right. I should probably reset the soc data. I just don't know how to solve it

    everything you wrote is correct. if I understand what you are saying. probably the eprom of the bms can't extract the real capacity of the cells, so it breaks it down ahead of time?

    the new battery is factory set for about 30 minutes of vacuuming. this pack with new cells, which have been tested with a tester, stops after 10 minutes of vacuuming. The new factory pack is 2000mAh.

    yes, there are new cells in it. but it doesn't perform as it should. there is not so much operating time. as with the old cells

    Yes. reset, the question is how is it possible?

    cells tested separately. the factory value is 2000mAh, the cell in it has a capacity of 1930mAh. Charger is good. We also use this for other accumulators. This is an upgraded pack that does not last as much as the factory one that is a few years old. Bms, doesn't the processor need to be reset...
