Frequently asked questions about custom lithium batteries

DtpGreen manufactures lithium polymer batteries, 18650 lithium-ion batteries, LiFePO4 batteries, special batteries, and custom lithium battery packs for OEM and ODM projects.

Yes. We can customize dimensions, voltage, capacity, discharge current, connector, wire length, protection board, label, packaging, and other project-specific details.

Lithium polymer is best for thin or shaped devices, 18650 cells are strong for cylindrical packs and higher energy density, while LiFePO4 is often preferred for long cycle life, thermal stability, and energy storage applications.

Yes. We support BMS selection and pack protection for overcharge, over-discharge, overcurrent, short circuit, temperature sensing, balancing, and other requirements.

Yes. Sample orders are available so your team can validate size, performance, connector, charging behavior, and product fit before volume production.

Please share voltage, capacity, maximum size, discharge current, charging method, connector type, wire length, application, certification needs, and estimated order quantity.

Sample MOQ can be flexible. Mass production MOQ depends on the cell model, pack structure, connector, label, and certification requirements.

For standard configurations, samples can move quickly. Fully custom packs may require additional time for design confirmation, material preparation, safety review, and testing.

Common support includes UN38.3, MSDS, CE, RoHS, CB, PSE, KC, BIS, UL-related documentation, and other project-specific compliance documents.

No. Requirements vary by destination country, product category, battery chemistry, energy rating, and shipping method. We help confirm the correct document path before production.

Yes. We can help prepare common transport documentation such as UN38.3, MSDS, packing information, labels, and logistics-related files when applicable.

You can visit the Battery Certificates page to view common certification categories and discuss the exact documentation needed for your project.

DtpGreen is a professional lithium battery manufacturer founded in 2008, offering integrated R&D, manufacturing, quality control, sales, and after-sales support.

Yes. DtpGreen supports OEM and ODM services, including battery pack design, sample validation, label customization, packaging, and production support.

We support consumer electronics, medical devices, beauty devices, power tools, model aircraft, low-temperature devices, IoT products, energy storage, and industrial equipment.

Quality control includes incoming material inspection, cell matching, pack assembly checks, protection board verification, aging tests, safety testing, and batch traceability.

Yes, but lithium batteries must follow transportation rules. We help coordinate compliant packaging, labels, documentation, and suitable logistics channels.

Packaging depends on the product and transport method. We focus on insulation, short-circuit prevention, carton strength, labels, and documentation for safe delivery.

Our team supports technical questions, usage guidance, failure analysis, replacement discussions, and improvement suggestions for future production batches.

Yes. We support repeat production with documented specifications, stable sourcing, production traceability, and engineering updates when components change.

Yes. We can support battery solutions for selected medical and health devices, with attention to safety, reliability, size constraints, and required documentation.

Yes. We can discuss low-temperature battery options for outdoor electronics, heated products, cold-chain devices, and winter-use applications.

Yes. We can evaluate discharge current, heat rise, cycle life, connector, wire gauge, and pack structure for high-power applications.

Sometimes. If voltage, current, connector, space, certification, and charging requirements align, a shared pack design can reduce cost and simplify inventory.

A simple estimate is runtime in hours equals battery capacity in Ah divided by device current in A. Real runtime may be lower because of efficiency loss, temperature, aging, and discharge cut-off voltage.

Use Wh = voltage x Ah. For example, a 3.7V 2000mAh battery is 3.7 x 2.0 = 7.4Wh.

Series connection increases voltage. Parallel connection increases capacity and current capability. A pack may combine both depending on the target voltage and runtime.

Yes. Share your device power consumption, target runtime, size limit, charging method, and working environment. Our engineers can recommend a practical battery specification.
