    Daly BMS 24V 8S 100A - poor balancing + charging and discharging prematurely stopped

    Is there any better BMS that does balancing battery cells even when discharging? (without Active Balancers) I think Daly BMS is a bad product for me. Too small balancing currents and it balances only when charging. Should the balancing be active in discharging, there will be no difference in...

    Daly BMS 24V 8S 100A - poor balancing + charging and discharging prematurely stopped

    24-27 V is too little power to operate a wheelchair. Even conventional lead-acid batteries would have a longer range.

    Daly BMS 24V 8S 100A - poor balancing + charging and discharging prematurely stopped

    Reversed plus a minus it is a failure on the code writer for the BMS? Is there any way to repair it? Does that mean there's a fault on the manufacturer's side? This means it is a defective product and I can return this BMS back to the seller ? It's frustrating. For a wheelchair, I need as much...

    Daly BMS 24V 8S 100A - poor balancing + charging and discharging prematurely stopped

    The balancing by bleeding off the high cell with a resistor .... I've done that with light bulbs several times. Some cell was always first on point 2.5V and turned off BMS, even though the other 7 cells still had 3.8V available.Thank you for your answers.

    Daly BMS 24V 8S 100A - poor balancing + charging and discharging prematurely stopped

    Is that necessary? I don't have a charger with 3,6V .... but 24V/20A only :-( I can balance cells only by a parallel connection between battery cells.

    Daly BMS 24V 8S 100A - poor balancing + charging and discharging prematurely stopped

    Ok. Now I charge the battery cells with a small current. (4A) After that, I'll do the discharging, maybe it'll be okay. If not, I'll have to buy an active balancer. BTW: I might have to buy a really active balancer because Daly BMS doesn't do balancing during discharging. Therefore, there is...

    Daly BMS 24V 8S 100A - poor balancing + charging and discharging prematurely stopped

    OMG! Thank you very much for the information. I will now do your procedure, which you recommended, that is very valuable to me!(y) BTW: Maybe I use a high charging current for this BMS. This BMS (Daly 8X 24V 100A) can be charged max. 50A. I use a 20A via this charger...

    Daly BMS 24V 8S 100A - poor balancing + charging and discharging prematurely stopped

    I agree, but there are two drawbacks: Only 1 battery cell is always fully charged at 3.65V. Then the BMS stops charging for the whole pack. The other 7 cells have 3.4V . 3.35V ... etc. (This is not fully charged) If 1 battery cell is dead to 2.5V, BMS is stopped even though the other 7 cells...

    Daly BMS 24V 8S 100A - poor balancing + charging and discharging prematurely stopped

    No. "0 %" point is not reached, but "100" % is always reached.

    Daly BMS 24V 8S 100A - poor balancing + charging and discharging prematurely stopped

    I did top balance the cells prior to assembling the pack. Wires are not reversed, its ok. Look at the video by a German seller,he has it the same way. I think I will need an active blancer because this BMS does not balance battery cells when discharging, but only when charging. I still don't...

    Daly BMS 24V 8S 100A - poor balancing + charging and discharging prematurely stopped

    (I apologize for my poor English) Yes, the packaging is well balanced. It has very litle balance current ? Not good for me :-( For the second problem - No, B- and P- wires are well connected. (B- to battey, P- to the power supply) I see the same problem with the German seller in his video...

    Daly BMS 24V 8S 100A - poor balancing + charging and discharging prematurely stopped

    A random battery cell of 8 pieces stops charging and discharging when it hits the highest or lowest point. (Daly BMS doesn't balance right) Daly BMS 24V 8S 100A (R16A-GA14) Software version/Firmware: 20201205-1.01G (sorry for my poor English) Charging: Once one cell hits 3.65V, then the...
