Your Source Custom Lithium Battery Pack Manufacturer
Don’t let power limitations dictate your product design. We bridge the gap between initial R&D and mass production.
Instead of forcing off-the-shelf batteries into your devices, our engineers design custom power solutions built precisely for your duty cycles, thermal environments, and strict dimensional constraints.
Scalable Manufacturing From Prototype to Production:
Whether you need 50 units for hardware validation or automated production runs of 50,000+, our flexible assembly lines adapt to your volume.
We ensure 100% cell consistency and strict BMS protocol matching from the first prototype to final delivery, guaranteeing top performance and durability for your intelligent devices.
Our Turnkey Battery Pack Engineering
As a source custom lithium battery pack manufacturer, we solve complex power challenges:
Cell Selection

How We Work With You For Your custom lithium battery pack project
A: For custom OEM battery packs, our standard MOQ is typically 50 to 1,000 units, depending on the complexity of the custom BMS and enclosure. However, we support low-volume prototyping runs (10-50 units) for initial hardware testing and validation.
A: The typical lead time for a custom battery prototype is 10 to 15 working days after the CAD drawing and BMS design are approved. For mass production, the lead time is generally 25 to 35 days, depending on material availability and order volume.
A: Yes. Every custom lithium battery pack we manufacture includes a highly reliable BMS. We can design the BMS with basic protection (overcharge, over-discharge, short circuit) or engineer a smart BMS with CANbus, RS485, or UART communication protocols for data tracking.
A: Absolutely. As an experienced custom lithium battery pack manufacturer, we provide standard UN38.3 and MSDS reports required for safe air and sea freight. We can also assist in applying for CE, UL, or IEC certifications under your company name for specific target markets.
A: Cell consistency is critical for battery lifespan. We use automated grading machines to sort 100% of incoming cells by voltage, internal resistance, and capacity. Cells are precisely matched before spot welding to ensure the pack remains balanced during charge and discharge cycles.
A: We offer flexible cell sourcing based on your project needs. We use Tier-1 imported cells like Samsung, LG, and Panasonic for high-end applications, as well as premium domestic Grade-A cells like CATL, EVE, and Gotion for highly cost-effective and reliable solutions.
