Why Work With Us
Your Trusted Partner in Lithium Battery Solutions
As a lithium battery manufacturer with nearly 20 years of practical industry experience, we build batteries that work as hard as you do. We’re not just another battery supplier—we’re a team committed to delivering safe, efficient, and reliable energy solutions for businesses around the globe.
We specialize in custom lithium battery solutions for a wide range of industries. From high energy density lithium batteries using NMC cells, to long cycle life LiFePO4 batteries, to deep cycle energy storage systems—our product line is built to handle real-world challenges.
Whether you’re looking for a lithium battery for RVs, forklifts, golf carts, solar energy systems, or industrial backup applications, we’ve got you covered.
Built for Demanding Environments
Power outages, extreme temperatures, remote conditions—our batteries are made to endure it all. Every unit is engineered to operate reliably in environments ranging from -4°F to 122°F (-20°C to 50°C). That makes them ideal for both indoor systems and rugged outdoor applications.
Each pack includes a smart battery management system (BMS) that constantly monitors performance and keeps everything running smoothly. This reduces the need for manual checks, lowers maintenance costs by up to 50%, and gives you the confidence to run your operation without interruptions.
Safe. Certified. Tested.
All of our batteries are produced in an ISO certified battery factory and carry international certifications, including UL, CE, IEC, and TLC. Each product goes through rigorous quality testing to meet the highest safety and reliability standards. We don’t cut corners, because your business depends on it.
Scalable Production for Any Order Size
With a production output of nearly 4 million batteries per month and an annual capacity of 6 GWh, we can fulfill both small custom orders and high-volume procurement with short lead times. Our ability to scale ensures you’re never left waiting—whether you’re sourcing for a startup project or supplying power for a nationwide rollout.
As an OEM lithium battery pack provider and private label battery manufacturer, we tailor every battery to your exact needs. From custom 48V lithium battery solutions to complete solar energy storage battery systems, we deliver what fits your application—not just what’s in stock.
A Commitment to Sustainable Power
We believe great batteries shouldn’t come at the cost of the planet. That’s why we invest in eco-friendly battery production, use recyclable materials, and follow clean manufacturing processes that reduce waste and emissions.
We also offer battery recycling programs to ensure that once your pack reaches the end of its life, it’s properly handled. It’s our way of helping you meet your sustainability goals—and a promise to do our part in the shift toward a cleaner, greener future.
Powering the Future, Together
You’re not just buying a battery. You’re building a power system that supports your business, protects your investment, and helps move the world forward.
