1. Leading Large Capacity: Advanced battery technology and high-quality battery materials enable it to achieve excellent high-capacity performance. By optimizing the structural design and chemical formula of the battery, we can provide higher energy density and charge storage capacity while maintaining a relatively compact battery volume.

2. Aluminum alloy base plate: The aluminum alloy base plate has excellent strength and durability and can withstand the stress and pressure of the battery during movement and vibration. This strength and durability ensure the stability and reliability of the battery in various complex road conditions and environments.

3. Specially developed nickel sheet: The specially developed nickel sheet has excellent conductivity and can effectively conduct current between battery cells. This conductivity ensures low resistance and efficient energy conversion of the battery at high power output, providing strong power support for electric bicycles.

4. Environmental protection of battery materials: Compared to traditional lead-acid batteries, lithium iron phosphate lithium batteries do not contain harmful heavy metals such as lead, mercury, and cadmium. This reduces the negative impact on the environment and human health and aligns with modern society's demand for environmentally friendly products.
