Product Description

2020 new LiFePO4 lithium battery pack 48V 30AH 50AH with over 1000 cycles lifetime

Battery is the new form of "fuel" for electric vehicles, you never need to go to gasoline station to refuel your outboard anymore. 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 our 
Scalable 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.

Innovation in Li-ion Battery
LiFePO4Power Battery: Faster charging and safer performance

It is clear that the small capacity Li-ion (polymer) Battery containing 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 LiFePO4 battery 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. LiFePO4 battery 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 performance
A LiCoO2 battery 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 LiFePO4 battery 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 LiFePO4 verse 1600J/g for LiCoO2 . 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 LiFePO4 battery 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 LiFePO4 battery is similar to lead-acid battery.

3. Self balance
Alike lead-acid battery, a number of LiFePO4 cells 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 charger
Large overcharge tolerance and self-balance character of LiFePO4 battery would simplify battery protection and balance circuit boards, lowering their cost. One step charging process would allow to use simpler conventional power supplier to charge LiFePO4 battery instead to use a expensive professional Li-ion battery charger.

5. Longer cycle life
In comparison with LiCoO2 battery which has a cycle life of 400 cycles, LiFePO4 battery extends its cycle life up to 2000 cycles.

6. High temperature performance
It is detrimental to have a LiCoO2 battery working at elevated temperature, such as 60C.. However, a LiFePO4 battery runs better at elevated temperature, offering 10% more capacity, due to higher lithium ionic conductivity.
