Our Advantages for BMS

1. Complete Function: Detect and protect the battery from: over-charge, over-dicharge,
                                                                         over-current, short-circuit,
                temperature detecting protection, auotmatically voltage balance function.
 
2. Build with high end electronic components (High End IC and MOSFET ) ,

3. Simple structure design will let it have more stable quality working performance , 

4. Flexible application ( it can be used for less series battery by leaving some connection pins at empty status ),

5. Full set of protection measures let it works well

6. Without any infulence from external unexpected accidents.
