Product Feature
▲Ultimate safety: Stainless steel material has extremely high mechanical strength, resistance to impact, compression, and puncture, which can effectively resist external collisions and prevent internal short circuits caused by battery deformation.
▲Comprehensive protection: With a high sealing structure, it effectively prevents dust, water, and moisture, adapts to rainy weather and complex road conditions, and extends battery life.
▲Excellent heat dissipation: Scientifically designed heat dissipation ducts or reserved installation positions for heat dissipation fins, combined with the excellent thermal conductivity of metals, help the battery pack quickly dissipate heat during operation and avoid overheating.
▲Corrosion resistance and durability: Stainless steel itself has excellent corrosion resistance, is not afraid of rain and salt spray erosion, does not rust after long-term use, and has a long-lasting appearance like new.
▲Lightweight design: While ensuring strength, weight is controlled through structural optimization to reduce the burden on the entire vehicle.
▲Intelligent integration: The internal layout is reasonable, making it easy to arrange battery cells, fix BMS, and organize wiring harnesses. It supports the integration of extended functions such as intelligent locks and positioning modules.
▲Beautiful and elegant: Modern industrial design with simple and smooth lines enhances the overall texture of the vehicle.

FAQ
Q1: What are the advantages of stainless steel shells compared to aluminum or plastic shells?
A1: Stainless steel casing has absolute advantages in structural strength and protection level, especially suitable for application scenarios that require high impact resistance and puncture resistance (such as shared electric bicycles and outdoor vehicles). Its durability and corrosion resistance are also superior to aluminum and plastic shells.
Q2: How to ensure the waterproof performance of the shell?
A2: We ensure seam sealing by laser welding the main structure, and use silicone waterproof gaskets and waterproof joints at all openings. We also undergo IP level water spray testing before leaving the factory to ensure compliance with the specified protection standards.
Q3: Can I customize special shapes or colors?
A3: Okay. We support customized customization based entirely on your installation space. The surface of the shell can also be treated with spray coating, baking paint, etc. to match the brand color of your entire vehicle.
Q4: How is heat dissipation solved?
A4: We adopt multiple solutions: ① Design a thermal conduction path internally to conduct heat to the outer shell for dissipation; ② Design heat dissipation grille holes on the non sealing surface of the shell; ③ Reserve a location for installing a cooling fan or water cooling plate. The specific plan is determined based on the heat generation of the battery.
Q5: What is the minimum order quantity (MOQ)?
A5: For standard models, the MOQ is usually 100 pieces. For fully customized models, MOQ needs to be evaluated based on the complexity of the design. Please feel free to consult for specific details.
Q6: How long does the production cycle take?
A6: The sample stage usually takes 10-15 working days. The batch production time depends on the number of orders, usually around 20-30 working days for a 500 piece order.
