BMS 7s 20A with Connector for 18650 Battery with Customized software 7S 15A 24V 29.4V PCB

7S 15A 24V 29.4V Battery Charging Module PCB BMS Protection Board for 7 Series Lithium LicoO2 Limn2O4 18650 Battery - with Customized Function

7S 20A 24V BMS BALANCE COMMON PORT CHARGE PROTECTION BOARD 3.7 LI-ION CELL for NMC 3.7V 7S Series 24V Lithium-ion Battery Pack 7S20A BMS board


  • 24V 25Amp 7S BMS
  • Battery Management System,Battery Protection Board,Balancing Function
  • Common Port Over Heat Cut-Off (Temperature Sensor) Splash Proof Over-Charge Protection Over-Discharge Protectio
  • Voltage Range = 21V to 29.4V
  • Max Charging Current = 10Amp,Max Discharge Current = 25Amp

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
