Frequently Asked Questions

1. How do I choose the right cylindrical cell (18650, 21700, 26650, etc.) for my custom battery pack?

The choice depends on your specific needs. 18650s are best for cost-effective, proven reliability. 21700s are ideal when you need higher energy density in a slightly larger footprint. 26650 and 32650 (often LiFePO4) are perfect for large-scale energy storage and long cycle life, while 14500s are suited for compact, AA-sized device replacements. Our engineering team will help you select the optimal cell based on your space, voltage, and capacity requirements.

2. Do your custom battery packs include a Battery Management System (BMS)?

Yes. At HiMAX, every custom lithium battery pack is integrated with a customized BMS. This ensures protection against overcharging, over-discharging, short circuits, and thermal runaway, maximizing both safety and battery lifespan.

3. What certifications do HiMAX custom battery packs hold?

We prioritize safety and global compliance. Depending on your target market, our customized battery packs can be certified with UN38.3, CE, RoHS, FCC, UL, and IEC62133, ensuring smooth international shipping and market entry.

4. What is the typical lead time for an OEM/ODM battery pack prototype?

Typically, once the technical specifications are confirmed, our R&D team can design and deliver a functional prototype within 10 to 15 working days. Mass production lead times vary based on order volume and material availability.

5. What is the Minimum Order Quantity (MOQ) for custom battery pack manufacturing?

As a B2B manufacturer, we are flexible to support your project phases. While mass production offers the best pricing, we do support lower MOQs for initial pilot runs and testing. Please contact our sales team with your project details for specific MOQ information.
