Frequently Asked Questions

Can you build custom battery packs based on our specifications?

Yes. We support custom lithium battery pack development based on your voltage, capacity, size, discharge current, application, enclosure, wiring, connector, BMS, and charging requirements.For each project, we review the working environment, installation space, runtime target, safety requirements, and shipping destination before providing a practical solution.
What information do you need for a custom battery pack quotation?


To prepare an accurate quotation, please share the required voltage, capacity, dimensions, application, continuous and peak current, quantity, destination country, connector type, charging method, and any communication requirements such as CAN or RS485.

If you are replacing an existing battery, photos, labels, wiring details, and equipment information are also helpful.
Which battery cell brands can you source or assemble?

We can support lithium cell sourcing and custom pack assembly using premium cell brands such as Samsung, Molicel, LG, Panasonic, Murata, EVE, Ampace, and other qualified suppliers.Cell selection depends on the required capacity, discharge rate, cycle life, budget, and application environment.
Can you help us choose the right cell model for our project?

Yes. We can help compare suitable cell options based on energy density, discharge current, cycle life, availability, safety requirements, and cost.

For example, high-drain applications may require different cells than long-runtime storage or lead-acid replacement projects.
Do you support smart BMS options?

Yes. We can support BMS options for overcharge, over-discharge, over-current, short-circuit, temperature protection, cell balancing, and monitoring.For suitable projects, smart BMS options such as CAN, RS485, Bluetooth, or display communication can also be discussed.
Can you provide UN38.3, MSDS / SDS, and shipping documents?

We can support battery-related documentation based on the selected cells, pack design, shipping method, and destination market.Common documents may include UN38.3, MSDS / SDS, commercial invoice, packing list, and shipping-related information required for lithium battery transport.
Do you support Class 9 dangerous goods shipping?

Yes. Lithium batteries are often regulated as dangerous goods for international transport. We can help coordinate Class 9 DG shipping options by sea, air, or express channels depending on battery type, watt-hour rating, quantity, packaging method, and destination country.
Can you ship battery packs to Europe and North America?

Yes. We can support shipping coordination to Europe, North America, and other selected markets depending on the product type, battery specification, quantity, and available logistics channels.Before confirming an order, we review shipping feasibility, packaging requirements, and required documents with the customer.
Do you accept sample orders or small batch projects?

Yes. Sample orders and small batch projects can be discussed depending on the battery type, customization complexity, cell availability, tooling requirements, and testing needs.

For new projects, we usually recommend starting with requirement review and sample confirmation before moving to batch production.
What is your typical lead time?

Lead time depends on cell availability, pack complexity, BMS configuration, enclosure requirements, testing process, and order quantity.

Standard cell sourcing projects may move faster, while custom battery pack projects usually require additional time for design review, sample preparation, testing, and production.
