Customer Reviews
Ottimo arrivato pacco integro senza danni ne ammaccature materiale di qualità. Grazie

—— Fabrizio Brunetti

Thanks for big support! They are accepting our small order request. Products is jut fine.

—— Kenjiro Kasai

Items as described. Thanks!

—— Jared Schwartzentruber

Great attention for any query. Batteries take time to customs but when I have them, I have tested them and they work fine. I will buy again, a larger order. I recommend 100%. Thank you so much

Smart Lithium Battery BMS

Smart BMS 4S-7S Li-Ion LiFePo4 with parameter adjusting 4S 7S 8S 12S 13S 14S 15S 16S 17S 20S for Lithium Battery

 

Product name: Protection Circuit Module

Model No: PCM7S25A LN0725

Suitable for 4S to 7S lithium-ion/Lithium polymer/LiFePo4 battery packs

 

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

 

Specification(the criterion can be adjustable as custominzed):

Other Advantage:

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.
