    Crazy low prices on Aliexpress LifePO4 320A, with buyer protection?

    I contacted them on Friday, but got no response. My seller has many open disputes because they say in the comments that they have done the same to him as they have done to all of us. What is Aliexpress doing with this store? NOTHING. There still scamming hundreds of people every day.

    Hello, I got 16 cells from Luyuan and now I want to assemble them. I have thought about compressing them to hold more charge and discharge cycles. I have seen someone who directly uses a rod and squeezes the batteries on each side. Does anyone know how many Nm I should put on the torque...

    Energus Tiny BMS - User Experiences?

    I thought I was talking to some sales person with no interest in selling to me. It seems to be the rule, even though I had ordered 50 units. I understand that for them it is a ridiculous order if they have customers who buy 500 or 5000 units per month. I have been told that I ask too many...

    200A Smart BMS from LLT Power

    Well as long as they continue to sell the prior model which supports 8s and 16s then there's no problem. As far as I understood from Jaibaida, he never supported 8S. It was an engineer's mistake, which was later corrected. How much do Jaibaida charge per unit on Alibaba ? 79,90 USD Do you...

    200A Smart BMS from LLT Power

    Yes those models work but the one without the aluminum case the salesman told me that it does not work in 8S. I ordered 10 units and I told him that I wanted it for 24V and he told me that although it comes in the specification sheet could not be put in 8S.

    200A Smart BMS from LLT Power

    After a conversation with the seller he told me that there is an error and this model does not allow 8S = 24V It is only so that others who see it know it although the seller should have already warned.

    200A Smart BMS from LLT Power

    I don't want to turn it off manually. I wanted to know if when the batteries are full in case the regulator fails it would only cut off the charge separately. Because if you cut everything and continue to enter electricity to the regulators would burn instantly.

    I had seen it in this battery and also I have seen a video where they press that round switch and you can hear the clack of the relay https://wecobatteries.com/oweephee/2020/09/5K3-WeCo-_LV_HV_Pagina_4.jpg

    Switch BMS

    ok, with this switch I cut all the power. I wanted to avoid putting this because it is too big and not very esthetic and use that small button to control the relay that does the same as I understand

    Do I need a BMS to charge the batteries?

    What about low battery cut-off? It can happen even if you put the inverter to cut-off voltage and wake up in the morning and the MPPT tries to charge and can not because the batteries are disconnected by low battery cut-off. I still say nonsense because I don't know how this bms works and what...

    Do I need a BMS to charge the batteries?

    Do you know what would happen with the MppT charge controller if the solar overkill BMS cuts the battery output current for any reason?

    Do I need a BMS to charge the batteries?

    Of course, I understand that it would still work because it is in parallel but it would swallow 12 kw of solar panel or it would know how to manage it to protect itself or it would damage the BMS? as I understand the BMS could with 5Kw of solar panel at 48v = 100Ah x 48v
