3S 4S 6S Li ion BMS with 50A constant charge and discharge current for electric tool ,electric vacuum cleaner,electric drill12.6V 16.8V 25.2V Lithium battery PCB

Description Application :This is The BMS for 3S 4S 6S  Lithium  battery pack  with 50A constant constant discharge current ,Which would be applied for  Electric tool Li ion Battery , electric vacuum cleaner Battery , Electric vehicle Battery system etc .  Function :This BMS has such basic functions : over-charge protection ,over-discharge protection, over-current protection , short-circuit protection.  Advantages :This BMS was build with high end Integrated electronic components (High End IC and MOSFET ) ,simple structure design will let it have more stable quality working performance . Specification reference :    Rated work voltage Between B and B- : 30V    Rated constant discharge current : 50A    Peak start Current : Max 100A    Max voltage between P and P-: 40V    overcharge detection voltage :4.225±0.025V    Overcharge release voltage :4.005±0.05V    over-discharge detection voltage :2.7V±0.05V    Over-discharge release voltage :2.95±0.05V    Over-current protection current :100±10A    Short Protection current : 100A    Self-consumption current  in working process : less than 15uA    Self-consumption current in stand-by Process : less than 2.5uA   Working temperature :-40~85°C   3S 4S 6S Li ion Battery BMS with 50A constant current for electric tool ,electric vacuum cleaner ,electric skateboard etc Connection instructions :    1. please use short and Bold wire to Connect B- to the Battery negative Port ,and then connect wires to the Battery at first , then plug connector into the BMS ( wrong connection order will damage the BMS surely )  2. Warning : the wire from  B- to battery negative port should be short and bold enough to prevent wrong protection action from the BMS during charge and discharge ,    P- and P wire should use bold wire also , the thin and long wire for connection P and P- will have the risk to burn the BMS please take much attention on these poins kindly Shipment :  Please choose the shipment way as you like ,you you can consider express delivery way if your order is urgent , but you should afford the extra freight cost by express delivery .   As post by air ,usually it takes around 20-60 days ,please notice it and do not open the disputes easily before reaching the contact with us ,we will try our best to solve the problem with our joint efforts .  Transaction terms : We guarantee the product  from us with a 12 months warranty against defects in quality, but we are not responsible for buyers’ mistake or wrong handling, our product must be maintained in proper way. If Item is defective and not working on arrival, please report the item to us within 7 days of receiving the defective product so we can issue a RMA.
