51.2V 100A 5KW Lithium LiFePo4 Battery For Electric Bicycles
51.2V 100A 5kw lithium battery
The Lithium Iron Phosphate Battery refers to the lithium-ion battery with LiFePo4 as the positive electrode material. The anode materials of lithium-ion batteries mainly include lithium cobaltate, lithium manganate, lithium nickelate, ternary materials, lithium iron phosphate, and so on, among which lithium cobaltate is the anode material used in the vast majority of lithium-ion batteries. In terms of material principle, lithium phosphate also contains an embedding and de-embedding process, the same as lithium cobalt and lithium manganese.
We designed the new 51.2v lifepo4 battery pack using high-quality lithium phosphate cells with the highest safety standards and optimized battery architecture. With the most advanced BMS to provide comprehensive protection function and real-time monitoring, it is suitable for RV energy storage power supply, electric vehicles, solar/wind energy storage systems, backup power supply, telecommunications, medical equipment, mobile power stations, solar energy storage, advertising vehicles, communication command vehicles, mobile vehicles, low-speed electric four-wheelers, industrial automation electrical equipment, UPS emergency power supply, etc.
The characteristics of the 51.2V Lifepo4 Battery:
1. Longer cycle life: Compared to the lead-acid battery, its cycle life is 10 times longer, and float charge/calendar life is 5 times longer, helping to minimize replacement costs and reduce the total cost of ownership.
2. Lighter weight: It is about 40% the weight of the comparable lead-acid battery, making it a “direct” alternative to the lead-acid battery.
3. Higher power: It provides twice the power of the lead-acid battery and even a high discharge rate while maintaining a high energy capacity.
4. Wider temperature range: -20℃~60℃
5. Excellent security: Lithium iron phosphate chemistry eliminates the risk of explosion or combustion due to high impact, overcharging, or short circuit conditions.
6. No memory effect: It supports the utilization of Unstable Partial State of Charge (UPSOC) (charge/discharge).
