Information :
1. Battery Management System for 11.1V 3S Li-ion and Li-polymer battery pack;
2. BMS applies for 3 cells Li-ion/Li-polymer battery pack;
3. with short circuit/over current protection;
4. With cell balance 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.
Our service and advantage:
1. The quotation for PCB will be sent in half an hour and PCBA will be sent in 24 hours. Please provide your projects with Gerber
file, Specis and BOM list.
2. PCB and PCBA clone are provided, please kindly send 2 samples.
3. For bulk order, we could provide free samples.
4. You could choose T/T, Western Union or Paypal to arrange the payment.
Own factory, better quality, better price!
The PCB factory which we cooperated has more than 14 years of Experience in PCB Industry,
There are more than 600 employees and four factories; one factory for prototypes, one for mass production, one for aluminum and copper PCBs, and one for PCB assembly. Each factory has the ability to make 8,000 square meters per month and we offer 1,000 kinds of PCB fabrication monthly, including one- to 20-layer PCBs, HDI, aluminum, heavy copper and halogen-free PCBs.
With the powerful support from the partner, we Have confidence to give our customers best service.
