1. Product DescriptionAbout your products,just tell us the relative voltage/ cells/ current A or equipment etc,We will help to recommend the most suitable products for you. Product Advantages:Supply OEM/ODM and custom serviceHigh quality with smart balance functionWholesale priceISO9001/ISO14001/CE/ROHS certificatesFast deliveryGreen productOne year warrantyExcellent safety performance Short circuit testing passedOvercharge testing passedOver discharge testing passedOriginal imported :IC from Japan,MOS from USA,Components from Sumsang. 1.2m drop testing passed100% testing Support ODM & OEM services  About the battery BMS/PCB/PCMFunction: Detect and protect the battery from over-charge  ,over-dicharge, over-current short-circuit ,temperature detecting protection and auotmatically voltage balance function .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.  Shenzhen Li-ion Battery Bodyguard Technology Co.,LTD PCM Specifications  For 18.5V(5S)Li-ion Battery PacksModel: LWS-5S20A-306(5S)Same PortNo.Test   itemCriterion1VoltageCharging voltageDC:21V  4.2/CellBalance voltage for single cell/2CurrentBalance current for single cell/Current consumption ≤20μAMaximal continuous charging current20AMaximal continuous Discharging current20A3Over charge ProtectionOver charge detection voltage for single cell4.25±0.025VOver charge detection delay time0.5S-1.5SOver charge release voltage for single cell4.15±0.05V4Over discharge protectionOver discharge detection voltage for single cell2.70±0.05VOver discharge detection delay time1000mS-2000mSOver discharge release voltage for single cell3.0±0.10V5Over current protectionOver current detection voltage100±25mvOver current detection current80±10ADetection delay time  1000ms-2000msRelease conditionCut load6Short protectionDetection conditionExterior short circuitDetection delay time200-500usRelease conditionCut load7ResistanceProtection  circuitry(MOSFET)≤20mΩ8TemperatureOperating Temperature Range-20 ~+70ºCStorage Temperature Range-40~+125ºC   2. Company InformationHot selling PCM model:      3. Packaging & Shipping & Payment  4. FAQQ:  How many Ampere protection circuit boards should choose?A: It depends on your load power such as electric motor power please contact the sales or technical support before buying. Q:  What is the distinction between same port wiring and different port wiring?A: The cathode of charger and load is different for different port wiring , the cathode of charger and load is same for same port wiring and the charging current is equal to the discharge current.  Q:  What is the distinction between balance and unbalance function?A: Equilibrium function is that high voltage cells will be discharged with resistor, waiting for the low voltage cells , to achieve the each cell voltage is consistent , to improve the battery performance for the whole group. Q: Do you have Minimum Order Requirement (MOQ)?A: No, We don't have MOQ, Different customer have different requirement ,We can provide various capacity and size is per your requirements,Also ODM / OEM is welcome. Q:  What is your term of payment?A: PayPal, T/T, L/C,5.
