3S 4S 5S 6S 7S 8S SIB LTO Li ion Lifepo4 Battery BMS with 120A Constant discharge current for sodium ion or Lithium titanate battery

Description Application :This is The BMS for 3S ~8S Li ion /Lifepo4/ LTO /SIB battery   with 120A constant constant discharge current ,Which would be applied for different project based on your battery specification  Function :This BMS has such basic functions : over-charge protection ,over-discharge protection, over-current protection , short-circuit protection. Balance , High temperature protection etc  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 constant discharge current : 120A    Peak start Current : Max 300A    overcharge detection voltage :4.25V For Li ion NCM Battery /3.65V For lifepo4 battery/2.85V For LTO Battery/3.95V For SIB Battery /    Overcharge release voltage :4.05V For Li ion NCM Battery /3.5V For lifepo4 battery/2.75V For LTO Battery/3.80V For SIB Battery /    over-discharge detection voltage :2.75V For Li ion NCM Battery /2.3V For lifepo4 battery/1.7V For LTO Battery/1.50V For SIB Battery /    Over-discharge release voltage :3.0V For Li ion NCM Battery /2.7V For lifepo4 battery/1.8V For LTO Battery/2.00V For SIB Battery /    Over-current protection current :150±10A    Short Protection current : 500A    Self-consumption current  in working process : less than 25uA    Balance start voltage :3.7V For Li ion NCM Battery /3.45V For lifepo4 battery/2.5V For LTO Battery/3.00V For SIB Battery /   Working temperature :-40~85°C 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 15·25 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.
