4S or 3S 12V Lifepo4 Battery PCB for 14.4V or 14.6V Lifepo4 Battery of Back up power BMS and Power inverter Battery protection Circuit




Application :This is The PCB for 4 series 12V (14.4V)  Lifepo4 Battery pack ( typical votage for single cell  3.2V ,and
3.6V after  full charge )with 50A constant discharge current .the charge and discharge port will be different
 Function :This BMS has such basic functions : over-charge protection ,over-dicharge protection, over-current protection ,
      short-circuit protection ,auotmatically voltage balance function .
 Advantages :This BMS was 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.
