High-quality Li-polymer cells for wireless speaker device performance

Lithium-polymer batteries have a high energy density and are among the most powerful batteries. Compared to NiMH batteries, they have a low self-discharge rate and are not subject to memory effect. They do not require regular discharging so are low-maintenance. When correctly stored, these rechargeable batteries have a long service life, are durable and have a high number of possible charging cycles. Li-polymer batteries are used in various portable devices with high energy requirements e.g. powerbank, notebook computers, cameras and power tools. These batteries can also be used in wireless speaker applications.

Please note: We are a manufacturer of lithium batteries, providing replacement batteries production, they are not genuine and not authorised by the brand. But we ensure that all these batteres are compatible with the brand models, the quality may be even better.

Battery Package

Safe transportation

Each battery is packed in a PP bag and then put into the box. Each outer carton is made of thickened five-layer cardboard. For express delivery, the gross weight of each carton is not more than 10kg, and for ocean freight, the gross weight of each carton is not more than 15kg, which is convenient for customers to load and unload easily after receiving the goods.

About Us

A Lithium Ion Battery Manufacturer

Batterea.com, on behalf of Shenzhen Promax Technology Co., ltd, was founded in 2014, our office locates in Shenzhen, and our factory was launched in Dongguan. We are a professional manufacturer of Lithium ion batteries and li-polymer batteries with 9+ years of experience.

Provide replacement Battery services

Find original battery samples

Start by acquiring original branded batteries for analysis. Disassemble them carefully to understand their internal components, construction, and specifications. Conduct thorough research to ensure compliance with any patents or intellectual property rights.

Components Sourcing

Source high-quality materials and components that match those found in the original branded batteries. This includes battery cells, casing materials, connectors, protection circuitry, and other necessary components.

Samples & Manufacturing

The manufacturing process involves assembling the replacement batteries according to the specifications of the original branded batteries. This includes placing the battery cells into the casing, soldering connectors and circuitry, sealing the battery, and performing quality control checks at each step.

Quality Control

Implement stringent quality control measures throughout the production process to ensure that the replacement batteries meet the same performance, safety, and reliability standards as the original branded batteries. This may involve testing for capacity, voltage, current output, temperature resistance, and cycle life.

Package And labeling

Once the replacement batteries pass quality control checks, they are packaged and labeled to resemble the original branded batteries as closely as possible. This includes using similar packaging materials, branding, and labeling information to maintain consistency with the original products.

Customer Support and Feedback

Provide excellent customer support to address any inquiries, concerns, or issues that customers may have regarding the replacement batteries. Gather feedback from customers to identify areas for improvement and continuously refine the production process.

Provide Customized lithium battery pack Services

Custom Li-polymer battery packs are designed and manufactured to meet the unique needs of a particular device or application. The goal is to create a battery pack that seamlessly integrates with the device it powers.

Requirement Gathering and Design

Begin by gathering detailed requirements from the customer regarding their specific application, including voltage, capacity, size, shape, weight, and operating conditions. Work closely with the customer to design a custom lithium-ion battery that meets their exact specifications.

Cell Selection and Procurement

Select high-quality lithium-ion battery cells from reputable suppliers that match the specifications outlined in the design phase. Procure the necessary quantity of cells to fulfill the customer’s order.

Battery Pack Assembly

Assemble the custom battery packs using the selected lithium-ion cells and other necessary components such as battery management systems (BMS), connectors, casing materials, and thermal management solutions. Ensure that the assembly process follows strict quality control measures to guarantee the reliability and safety of the battery packs.

The REAL FACTORY/BATTERY Videos

We will conduct a thorough assessment of their performance based on the specifications or drawings confirmed by the customer. This assessment includes inspecting the outward appearance, battery label, printing, wires or wire connectors, voltage, internal resistance, and over current protection. If all these parameters meet the required standards, we will proceed with packing the batteries into cartons. However, if any of these aspects do not meet the specifications, the batteries will be returned to the Quality Control (QC) team for further analysis and necessary adjustments. This testing involves simulating real-world usage conditions to evaluate the battery pack’s performance and durability over an extended period.
