ODM/OEM Customized Solution

Customized integrated solution
In response to the different business needs of factories and battery traders, our company has developed exclusive full-chain customized solutions, providing one-stop services to achieve mutual benefit and win-win results:
Factory-specific customized solution
1. Structural / Parameter customization: Based on factory design drawings, adjust the battery installation slots and fixation methods to achieve seamless integration with the rear shelf; at the same time, support personalized debugging of BMS discharge parameters and charging protocols to ensure perfect matching with the motor and enhance power performance
2. Production delivery schedule guarantee: Relying on large-scale fully automated production lines, support batch delivery of large orders in batches, and can formulate exclusive production scheduling plans based on the factory's production schedule, reserve safety inventory to avoid affecting the production progress due to battery supply disruptions
3. Technology and qualification support: Provide a complete set of product installation drawings and technical guidance manuals, arrange professional engineers to interface with the assembly process, reduce the integration cost; at the same time, provide a complete set of international certifications such as CE, UN38.3, RoHS, and domestic inspection reports to help the factory obtain market access for both domestic and international vehicles
4. Production cost optimization: For long-term cooperative factories, formulate a stepped batch purchase price, combined with standardized production processes, optimize the vehicle component cost for the factory, and enhance the price competitiveness of the vehicle products
Battery trader-specific channel solution
1. Multi-brand compatibility and adaptation: For the replacement market of multiple brands and models covered by the trader, provide standardized adapters and assembly accessory packages, one battery can adapt to over 95% of the rear shelf models of electric bicycles on the market, significantly reducing inventory pressure and improving inventory turnover rate
2. Channel profit and protection: Formulate stepped wholesale prices, the larger the purchase volume, the higher the discount, ensuring sufficient profit space for the trader; at the same time, implement strict regional channel protection policies, strictly prohibiting cross-regional counterfeiting, maintaining the market order of the cooperative partner in the regional market
