You only need to recharge your batteries at home or docking place.Our expandable battery modules will make your life much easier to determine how big the battery bank you need to meet your purpose. You can just buy one battery module first to test performance and find out accurate amp draw for your special application, then you can easily figure out how many such battery modules required to get the EV speed and travel duration you want. You can easily parallel link up to 4 expandable battery modules to form a larger capacity battery bank by using ourScalable Battery Hub(QuadCell). You can use two such hubs to link up to 8 battery modules. Each battery module is light weight for one person to carry around. Each module has its own battery management system (built-in BMS) and charger. We have developed two models of battery module for diffrent electric boats, 48V30AH and 48V50AH. Their features and functions are basically same except they have different capacities. All have its built-in LED meter.We choose the most safe LiFePO4 battery type for our expanable battery modules, the materials used inside battery cell will not cause any fire or explosion. The quality of cell is very consistent and can last more than 2000 charging cycles. Its C-rating is 3 times, that means a single 48V50AH module can output 150A continuosly. That's why you can buy just one or two battery modules first, to test the motor performance and get amperage to calculate before you know the exact battery capacity you need.Module Specifications:EB-4830EB-4850Battery Type:LiFePo4Battery Type:LiFePo4Capacity:48V 30AhCapacity:48V 50AhBMS:IntelligentBMS:IntelligentCharging Cycles:>1000Charging Cycles:>1000Module Weight:16KgModule Weight:27KgMax Discharging:90AMax Discharging:150ACharger(110-240Vac):5ACharger(110-240Vac):8ACasing:Stainless SteelCasing:Stainless SteelEach model included:BMS / LEDEach model included:BMS / LEDMeter:Voltage, Current, Capacity %Meter:Voltage, Current, Capacity %Dimension:20x17x39cmDimension:31x18x40cmBattery Modules:QuadCell :IISETCCE CERTIFICATE with 4830IISETCCE CERTIFICATE with 4850Innovation in Li-ion BatteryLiFePO4Power Battery: Faster charging and safer performanceIt is clear that the small capacity Li-ion (polymer)Batterycontaining lithium cobalt oxide (LiCoO2) offers a genuinely viable option for electronics and digital applications. However, lithium cobalt oxide (LiCoO2) is very expensive and un-safe for large capacity Li-ion Battery. Recently lithium iron phosphate (LiFePO4) has been becoming "best-choice" materials in commercial Li-ion (polymer) Batteries for large capacity and high power applications, such as lap-top, power tools, e-wheel chair, e-bike, e-car and e-bus.A LiFePO4battery has hybrid characters: as safe as lead-acid battery and as powerful as lithium ion cells.The advantages of large format Li-ion (polymer) batteries containing lithium iron phosphate (LiFePO4) are listed as below:1. Fast charging:During charging process, a conventional Li-ion Battery containing lithium cobalt oxide (LiCoO2) needs two steps to be fully charged: step 1 is using constant current (CC) to get 60% State of Charge (SOC); step 2 takes place when charge voltage reaches 4.2V, upper limit of charging voltage, turning from CC to constant voltage (CV) while the charging current is taping down. The step 1 (60%SOC) needs two hours and the step 2 (40%SOC) needs another two hours. LiFePO4battery can be charged by only one step of CC to reach 95%SOC or be charged by CC+CV to get 100%SOC. The total charging time will be two hours.2. Large overcharge tolerance and safer performanceA LiCoO2battery has a very narrow overcharge tolerance, about 0.1V over 4.2V of charging voltage plateau and upper limit of charge voltage. Continuous charging over 4.3V would either damage the battery performance, such as cycle life, or result in firing and explosion. A LiFePO4battery has a much wider overcharge tolerance of about 0.7V from its charging voltage plateau 3.4V. Exothermic heat of chemical reaction with electrolyte measured by DSC after overcharge is only 90J/g for LiFePO4verse 1600J/g forLiCoO2.The more is the exothermic heat, the larger energy heating up the battery in its abusive condition, the more chance toward firing and explosion. A LiFePO4battery would be overcharged upto 30V without portection circuit board. It is suitable for large capacity and high power applications. From viewpoint of large overcharge tolerance and safety performance, a LiFePO4battery is similar to lead-acid battery.3. Self balanceAlike lead-acid battery, a number of LiFePO4cells in a battery pack in series connection would balance each other during charging process, due to large overcharge tolerance. This self balance character can allow 10% difference between cells for both voltage and capacity inconsistency.4. Simplifying battery management system (BMS) and battery chargerLargeovercharge tolerance and self-balance character of LiFePO4battery would simplify battery protection and balance circuit boards, lowering their cost. One step charging process would allowto usesimpler conventional power supplier to charge LiFePO4battery instead to use a expensive professional Li-ion battery charger.5. Longer cycle lifeIn comparison with LiCoO2battery which has a cycle life of 400 cycles, LiFePO4battery extends its cycle life up to 2000 cycles.6. High temperature performanceIt is detrimental to have a LiCoO2battery working at elevated temperature, such as 60C..However, a LiFePO4battery runs better at elevated temperature, offering 10% more capacity, due to higher lithium ionic conductivity.Why Choose US?Our Service:1.Reply your inquiry in24working hours.2.Customized design is available.OEM & ODMare welcomed.3.Professional engineers & Exclusive and unique solution.4.Well-trained staffs.5.Return Policy:For defective goods,please send us the pictures to confirm then we will give you the replacementduring warranty period.6.Warranty :We warrant that this product shall be free from defects in material or workmanship for 1 year from the date of purchase.The warranty of the battery is 1year from the date of purchase.This warranty does not apply to any product that has been subject to misuse,abuse,negligence or neglect.Defects caused by tempering ,alterations and /or repairs are not covered by this warranty.7.Payment :TT /PAYPALDealer Policy:1.Join Golden Motor Dealership Today -- Our website attracts and redirects over5000 potential buyers daily to our dealers worldwide!2.Now we have our180 dealersin the world.3.To be our dealer,you just place the first order worth of the minimum 10000$.4.When you are to be our dealer,your info will be put on our dealer page on our website.which have thousands of visitors every day.
