We combine advanced lithium battery engineering with precision manufacturing—delivering custom packs built for safety, performance, and long-term reliability across industries.
There are three common formats: cylindrical (e.g. 18650, 21700), prismatic, and pouch cells. Each type has different advantages in terms of energy density, mechanical structure, and design flexibility.
Lithium ions shuttle between the anode and cathode during charge and discharge.
During charging, ions move from the cathode to the anode; during discharging, they return to the cathode, releasing energy.
Typical PACK lines include cell sorters, laser welders, spot welders, insulation testers, and BMS programmers.
We use semi-automated or fully automated assembly, depending on order size and complexity.
Yes, we offer full customization.
This includes voltage, capacity, cell layout, connector type, case material, and communication protocol (CAN/RS485).
Essential documents include the spec sheet, wiring diagram, BMS protocol file, MSDS, UN38.3 test report, and Declaration of Conformity.
We provide all documentation needed for product approval and safe usage.
Our batteries can comply with UN38.3, CE, IEC 62133, MSDS, RoHS, UL, and more.
We can help arrange third-party testing if needed for specific markets.
Yes, we provide full technical support and after-sales service.
For B2B orders, we offer diagnosis assistance, replacement modules, and remote troubleshooting.
Yes. After the first life, batteries can be reused in low-power applications or properly recycled.
We support second-life planning and work with certified recycling partners.
Avoid overcharging, short-circuiting, or puncturing the battery.
Store in a dry, cool area. Always use compatible chargers and follow provided safety instructions.
Start by confirming your voltage, power, and size requirements.
We’ll help you match the right cell type, BMS specs, and enclosure for optimal performance and compliance.
