6S Li ion 25.2V or Lifepo4 21.9V Battery BMS with 40A constant current for inverter outdoors storage battery electric tool PCB board

Description This BMS was designed specially for 25.2V 6S Li ion or 21.9V Lifepo4 battery work for electric wheel or other application battery ,which can fit for various type of lithium ion chemistry such as :NCM battery ,lithium polymer battery and other li ion battery etc . Features and characteristics :  For 6S Li ion 25.2V or 6S Lifepo4  Battery application  With Balance function With full set of protection functions : such as Over-charge and over-discharge protection , over-current protectiton , short circuit protection ,temperature protection with extremly low quiescent current consumption with Same charge and discharge port Constant discharge : 40A Dimension :95*65*8mm Parameters reference : PARAMETERS REFERENCE : Constant  discharge current:    40A   Short circuit protection  External short / release it by disconnect the external short will recover Over current protection  100±20A  High temperature protection can be added if needs such function Charge current     20A   Balance  42±5mA  Charge voltage For 6S Lifepo4 Battery :6*3.65V=21.9V For 6S Lithium ion :6*4.2V=25.2V  Over-current protection current   20A :60A±8A       30A:80A±10A Overcharge protection cut-off voltage  Li ion :4.25V±0.025V        Lifepo4: 3.65V±0.025V Overcharge detection delay times  Max 1500mS Overdischarge cut-off voltage  Li ion :2.7V ±0.1V Lifepo4 :2.35±0.1V Over-discharge detection delay times  Max 1500mS Overdischarge release voltage  Li ion :3.0V ±0.05V /Lifepo4:2.5V ±0.05V  Self-current consumption Stand-by :    10uA         In working status : less than 40uA Dimension   95*65*8mm     Transaction terms : 1) Shipment time : once received your order ,we will proceed it quickly within 3~4 working days without problems .order can be cancled within these days ,otherwise we will reject to cancle the order ,because our items can not get back when in the process of shipment . we will inform our buyer if  there is a stock problems with the order and arrange a properly agreenment on the shipment schedule by email . 2) Shipment Methods : Client can choose suitable shipment methods based on your demand ,Post air parcel service or Express service , we will ship all orders strictly in according to the selected shipment methods by our customer . normally , Post parcel shipment time takes 7~60days depends on different countries serivce . and express takes 2~15days to the destination normally . 3) About Tracking number : Tracking number will be uploaded and will be informed by the registered email on each Friday ,please pay attention to your email later on for the tracking number update . 4) Quality Service : we will take a full responsibility for any defect product caused by our design and production problems ,warranty time is 12 months since the shipment date . but for any defect product caused by any wrong or slavery application from customers . we will not take the responsibility for that , because for this BMS product ,it do need some skills to make installation . please consult us in advance if you are not clearly with bms connection in the hope of avoid any mistakes of connection . if Buyer damaged the BMS , we can offer the free repairing service to our client , but client should take care of shipment cost .please know it kindly in advance . thanks Please send email to this address for any questions [email protected], we will give you reply within 12hours without problems .
