7S 29.4V 15A BMS Lithium Battery Protection Board 18650 Lion Lithium Short Circuit Overcurrent Protection Module
Product name: Protection Circuit Module (PCM)
Model No: PCM-LN0725-BMS Dimension only 56*46mm
Battery type:
PCM-L0725 7S BMS 29.4v Lithium Battery BMS Charging Voltage 29.4v 200A BMS PCM
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 influence from external unexpected accidents.
7S PCM standard data as follow, we are welcome any parameter by customized, such as current, charge and discharge protection data...

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) Blue tooth function ,then you can check the batteries status by your phone
we will help to recomment the most suitable products for you. or we design for you!
