Unlock Your Potential with Custom 18650 Lithium Battery Packs

In the rapidly evolving world of portable power, off-the-shelf batteries often fall short. Whether you're developing the next generation of drones, powering critical medical devices, or building high-performance robotics, your innovation deserves a power source engineered to match. This is where UTray's custom 18650 lithium battery pack service becomes your ultimate strategic partner. We specialize in transforming standard cylindrical lithium cells into sophisticated, application-specific power solutions.

Precision Engineering for Demanding Applications

Our core offering is bespoke battery assembly (PACK). We understand that a one-size-fits-all approach doesn't work for advanced technology. Using premium Grade A new cylindrical lithium cells with a silicon-carbon (Si-C) anode material, we build packs that offer an excellent balance of energy density, lifespan, and performance. The standard 3.7V nominal voltage and high 3000mAh typical capacity per cell provide a robust foundation, which we then tailor precisely to your needs.

Why Choose a Custom UTray Battery Solution?

• Complete Customization: From capacity and voltage to outer dimensions and shape, every parameter is built to your specifications. Need an异形 (special-shaped) battery for a compact space? We can produce it.
• Wide Application Versatility: Our batteries are engineered for medium-rate discharge, making them ideal for a vast range of products: Electric Tools, Smartphones, Digital Products, Drones, Home Energy Storage Systems, Electric Boats & Aircraft, Portable Medical Devices, Robots, and Garden Machinery.
• Rigorous Quality & Safety: Every pack is produced with CCC certification in mind, adhering to strict safety standards. With an operating temperature range of -20°C to +60°C and a one-year warranty, reliability is built-in.
• Streamlined Development: We handle the complex R&D and production of特种 (special) batteries, allowing you to focus on your core product development and accelerate your time-to-market.

Ideal for Innovators and OEMs

If your project has unique power requirements that standard batteries cannot meet, partnering with UTray is the solution. We bridge the gap between raw battery cells and a fully integrated, safe, and high-performing power system. Our made-in-China expertise ensures cost-effectiveness without compromising on the quality and performance demanded by global markets.
