    24V 7S BMS Battery Management System BMS 7S 20A With Connector For 18650 Battery

    BMS 7s 20A with Connector for 18650 Battery li ion bms pcb 24v 7s bms battery management system

    Lithium ion battery protection PCB protect single Lithium ion batteries and it has 20A continuous current. It is suitable for electric drills,motors,or aircraft models which require heavy current load.

    7S 24V 40A Lithium Ion BMS, with Balancing

    A battery management system (BMS) is essential in a lithium ion battery build. Li-ion batteries are much more sensitive to voltage than lead acid, and can be dangerous if over- or under-charged. It protects against over- and under-voltage as well as over-current, and ensures that the cells are balanced. This BMS is for a 7S (25.9v nominal) lithium ion battery, and allows 40 amps continuous discharge and 20 amps charge. 3S 4S 5S 6S 7S 15A 20A 18650 Lithium Battery Protection Board 12V 24V 29.4V Li-ion Packs BMS with Balance


    Function:

    Detect and protect the battery from over-charge ,over-dicharge, over-current short-circuit,temperature detecting protection and auotmatically voltage balance function .


    Build with high end electronic components (High End IC and MOSFET ) ,simple structure design will let it have more stable quality working performance , Flexible application ( it can be used for less series battery by leaving some connection pins at empty status ),full set of protection measures let it works well without any infulence from external unexpected accidents.


    About your products,just tell us the relative voltage/ cells/ current A or equipment etc,

    we will help to recomment the most suitable products for you. or we design for you!


    Any functions can be choose as follow:

    1) Power off detection (It can be locked when removed the PCM from battery pack, to avoid safety accidents caused by users unauthorized disassembly or replacement)


    2) MOS statistics of overtemperature protection times (it can lock up after N times overtemperature protection to avoid safety accidents caused by user overload)


    3) Power on timing (it can lock up after N years running, it means we can design a lock time depends on the batteries service life, then the user can’t replace the batteries by themself)


    4) Counting discharge times (It can design lock up after N times charge and discharge, then if can’t be work end of batteries service life )


    5) Add buzzer (it can make a sound to remind the user to charge when the battery is stored for a long time, the voltage is too low due to self discharge to protect batteries)


    6) Unique ID (a unique ID number can be added to each board for product tracing)


    7) UART communication (communication with PC can be realized, to setting and viewing the data of the above items 1-6 before delivery)


    8) Bluetooth function ,then you can check the batteries status by your phone
