Got Questions?
-
Q.
What specifications do you need to design a custom lithium battery pack?
To develop a suitable battery solution, we recommend providing your required voltage, capacity, maximum discharge current, available dimensions, operating temperature, and application details. Drawings, connector specifications, charging requirements, and estimated annual order quantities are also helpful. Our engineering team can review your requirements and recommend an appropriate cell configuration, BMS, and battery pack design.
-
Q.
What is the minimum order quantity (MOQ) for custom battery packs?
The minimum order quantity depends on the battery chemistry, cell availability, pack configuration, and customization complexity. Prototype quantities and mass production requirements are evaluated separately. For OEM/ODM projects, please share your estimated annual demand and technical specifications so our team can assess production feasibility and provide an appropriate quotation.
-
Q.
Can you customize battery voltage, capacity, size, BMS, and connectors?
Yes. GLOFLUX provides custom lithium-ion, lithium polymer, and LiFePO4 battery solutions for various applications. We can customize voltage, capacity, dimensions, cell configuration, protection circuits, wiring, connectors, and enclosures. Depending on project requirements, we also support NTC temperature monitoring and BMS communication interfaces such as SMBus, I²C, and CAN.
-
Q.
How long does custom battery prototype development take?
Prototype development typically takes around 2–4 weeks after technical specifications and design requirements are confirmed. The actual timeline depends on cell availability, PCB or BMS development, mechanical design, and testing requirements. Our team can provide a project-specific schedule before sampling. Prototype testing helps verify electrical performance, mechanical compatibility, and charging behavior before mass production.
-
Q.
What certifications are required for custom lithium battery packs?
Certification requirements depend on the battery design, application, and target market. Common standards and regulations include UN38.3, IEC 62133, UL 2054, UL 1973, and applicable CE requirements. GLOFLUX can provide available cell documentation and assist with certification planning. A newly assembled custom battery pack may require additional testing or certification, even when its individual cells are already certified.
-
Q.
Can GLOFLUX support mass production after prototype approval?
Yes. GLOFLUX supports OEM/ODM battery projects from engineering evaluation and prototype development to production planning and manufacturing. After sample validation and final specification approval, our team coordinates material sourcing, assembly, quality inspection, and production scheduling. Lead times and production quantities are confirmed according to the approved battery design and order requirements.
