Frequently Asked Questions
Q: What is the minimum order quantity for a custom LiFePO4 battery pack?
For prototype orders, our MOQ is 1 unit. For mass production runs, the MOQ depends on the complexity of the design and typically starts at 50 units. We offer full engineering support from a single prototype through to high-volume manufacturing with no compromise on quality or attention to detail. Early-stage startups and research institutions are welcome - we have dedicated prototype allocation capacity.
Q: Which cell brands do you use in your custom battery packs?
We work exclusively with Tier-1 cell manufacturers including CATL, EVE Energy, and CALB. Clients can specify their preferred cell brand and model during the design phase. Our procurement team ensures consistent supply with full traceability from cell lot to finished pack. We also provide cell selection guidance based on energy density, cycle life, discharge rate, and cost optimization requirements for your specific use case.
Q:How long does the custom battery pack development process take?
Typical lead times are: prototype phase 2–4 weeks, testing and validation 2–3 weeks, and mass production tooling 4–6 weeks. Complex designs with custom BMS firmware, unique enclosure molds, or extreme environmental ratings may require additional time. We provide a detailed Gantt-chart project timeline at the quotation stage so you can plan your product launch with confidence. Rush services are available for time-critical projects.
