2S Lithium Ion BMS Board

Description of 2S Lithium Ion BMS Board

Lithium batteries is now very popular of their superior performance. But for imbalance charging, over discharging, over charging and short-circuit may damage the battery performance. To optimize the battery performance, maximize lifetime and ensuring safe operation is mandatory. Only a well-designed Battery Management System (BMS) can protects and monitors a lithium battery during charging and discharging.

Feature:

• Over and Under Voltage Protection

• Overcurrent and Short-Circuit Protection

• Balance Charging

Note: Output terminal (P+ & P-) will be at 0V initially after attaching batteries between (B+ & BM) and (B- & BM). You need to put external 8.4V between P+ & P- for about 3 seconds to "activate" the BMS board. After that, P+ & P- will provide voltage output according to battery voltage.
