Enter UTrust's custom 18650 and polymer lithium battery pack service. We specialize in transforming standard lithium-ion technology into tailored power solutions designed for your exact application. Whether you're developing the next generation of electric tools, robotics, or smart digital products, our engineering team is equipped to deliver.

Engineered for Excellence: Core Specifications

Our foundation is built on quality and flexibility. Every battery pack starts with brand-new, Grade A cylindrical 18650 lithium cells, ensuring consistency, safety, and long cycle life. A standout offering is our high-capacity 3000mAh cell, providing extended runtimes for demanding applications.

• Standard Voltage: 3.7V (Configurable for various pack voltages)
• Key Application Areas: Drones (UAVs), Electric Tools, Robotics, Portable Medical Equipment, Smart Digital Devices, Garden Machinery, Home Energy Storage Systems.
• Operational Resilience: A wide operating temperature range of -20°C to +60°C ensures performance in diverse conditions.
• Certification & Safety: Full CCC (China Compulsory Certification) compliance guarantees adherence to stringent national safety standards.

The UTrust Advantage: Complete Customization

One-size-fits-all doesn't apply to advanced electronics. Our Processing Customization service is our core strength. We don't just sell batteries; we co-engineer power solutions.

• Shape & Size: Require an unconventional, space-saving form factor? Our polymer lithium battery capabilities allow for custom shapes and dimensions (As per custom demand) to fit seamlessly into your product design.
• Capacity & Configuration: Need a specific energy density or voltage? We build packs to your required capacity and series/parallel configuration, optimizing balance between size, weight, and power.
• BMS Integration: We can integrate advanced Battery Management Systems (BMS) for protection against over-charge, over-discharge, short circuits, and excessive current, crucial for the safety of sensitive devices like medical equipment.

Ideal for High-Demand Sectors

Our batteries are engineered for medium-rate discharge, making them perfect for applications that require sustained, robust power rather than brief, extreme bursts.

For Drone & UAV Manufacturers: Lightweight, high-capacity packs that maximize flight time and provide stable voltage output for motors and avionics. The silicon-carbon based material enhances energy density.

For Professional Power Tool Brands: Deliver the consistent torque and runtime professionals demand. Our packs are built to handle the vibrations and shocks typical in workshop and job site environments.

For Portable Medical Device Innovators: Reliability is non-negotiable. Our certified packs ensure safe, long-lasting operation for diagnostic tools, mobile monitors, and other critical healthcare technology.
