About Dumfume
Dumfume – Factory-Direct LiFePO₄ Energy You Can Trust
In the heart of China's lithium battery manufacturing hub—Shenzhen—a team of engineers and energy enthusiasts founded Dumfume with a clear goal: to make high-performance, safe LiFePO4 batteries directly accessible to everyone. We saw that quality energy storage was often expensive or locked behind complex supply chains. So we built a different model: a factory-direct, online brand that brings advanced battery technology straight from our production line to your home, RV, boat, or off-grid system.
Welcome to Dumfume, operated by Shenzhen Qiangzhong E-commerce Co., Ltd. We are a direct-to-consumer brand specializing in premium lithium iron phosphate (LiFePO₄) batteries. Our products are engineered for real-world reliability across diverse applications—from RVs and off-grid living to home energy storage, marine use, and golf carts.
By designing, overseeing production, and selling online ourselves, we ensure strict quality control, competitive pricing, and dedicated customer support. Our growing community spans the United States, Canada, Australia, Germany, and across Europe, with fast shipping from local warehouses in key regions.
