1. Leading High Capacity: Advanced battery technology and high-quality battery materials result in exceptional high-capacity performance. By optimizing the battery's structural design and chemical formulation, we achieve higher energy density and charge storage capabilities while maintaining a relatively compact battery size.
2. Aluminum Alloy Base Plate: The aluminum alloy base plate boasts excellent strength and durability, allowing it to withstand the stresses and pressures experienced during movement and vibration. This strength and durability ensure the battery's stability and reliability in various complex road conditions and environments.
3. Specially Developed Nickel Plates: The specially developed nickel plates feature outstanding conductivity, effectively transmitting current between battery cells. This conductivity ensures low resistance and efficient energy conversion during high power output, providing robust power support for electric bicycles.
4. Eco-Friendly Battery Materials: Compared to traditional lead-acid batteries, lithium iron phosphate (LiFePO4) batteries are free from harmful heavy metals such as lead, mercury, and cadmium. This reduces the negative impact on the environment and human health, aligning with modern societal demands for environmentally friendly products.
