li-ion BMS PCM 18650 Battery Protection Board PCB for 18650 Lithium ion li Battery 7S smart PCM OEM service
25A BMS 6S 7S 8S 9S 10S 11S 12S 13S 18650 Li-Ion Battery PCM Protection Board
About the battery BMS/PCB/PCM
Battery Management System ( BMS ) Modules All 1S 2S 3S 4S 5S 6S 7S 8S BMS and Amps Range 3A 5A 10A 20A 25A 30A 40A 60A 100A
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.
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
