CLF Industry Battery Solutions

Custom lithium battery packs, energy storage systems, and electrical assemblies for OEM/ODM projects across mobility, industrial equipment, power backup, and renewable energy.


CLF (Changlong Fly) provides custom lithium battery solutions for multiple industries, including Energy Storage (home & C&I ESS), Data Center & IT Room power backup, Motive Power (marine, floor cleaning machines, aerial work platforms, medical carts, low-speed EV, RV, lawn mowers), and Wire Harnesses & Cable Assemblies for battery systems and equipment integration. We support LiFePO₄ and other chemistry options based on project requirements.


Beyond standard voltage platforms (12V/24V/48V), we build scalable configurations for different system architectures, including rack modules, cabinets, and project-based solutions. Our engineering support covers battery pack design, BMS protection (OVP/UVP/OCP/OTP/SCP), and communication integration (RS485/RS232/CAN) when required. For wiring and integration projects, we also provide harness design, connector matching, and assembly support to ensure reliable installation and serviceability.


We work with OEM/ODM customers from concept to delivery: requirement clarification → technical proposal → sampling → mass production. To recommend the right solution, please share your application, target voltage/capacity, power or load profile, installation constraints, and compliance requirements for your market. CLF can provide fast quotation, engineering drawing support, and project documentation based on your needs.
