24V 7S 16A/25A/35A/45A/60A Li-ion battery Protection Board BMS PCB PCM

7S 24V 20A Lithium Li-Ion Lifepo4 18650 Battery Bms Pcb Pcm


Feature:

1. Protection Circuit Board for 37V 10S Li-ion and Li-polymer battery pack;
2. BMS applies for 10 cells Li-ion/Li-polymer battery in series;
3. To prevent the battery packs from overcharge,overdischarge,over current, over temperature ,short circuit ;
4. With cell balance/equilibrium function;
5. Compatible with both Li-ion and Li-Polymer cells.

6. How balancing function works? after battery pack is fully charged. PCM will detect each cell's voltage and trim higher voltage down until other cells reach the same voltage level. Therefore, it helps cells have longer service life.


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
