BigBattery

BigBattery is an energy storage manufacturer and distributor headquartered in Commerce, Texas. Founded by Eric Lundgren, the company was built on a simple but powerful mission: make energy storage affordable enough to drive the mass adoption of renewable energy. While the cost of generating solar power has dropped dramatically, batteries have remained expensive, and BigBattery set out to change that.

What sets BigBattery apart is their commitment to durability, repairability, and value. In a market full of disposable designs, their products are built to last, with modular components that are easily swappable and never proprietary. They're strong advocates of the Right to Repair movement, and that philosophy shows up in everything they build. All of their batteries use Tier 1 LiFePO4 cells with advanced BMS protection and carry a 12-year warranty.

Beyond their own battery systems, BigBattery distributes complementary products that meet the same standards their customers expect — affordable, well-built, and designed to last. That's why they carry Eneramp inverters alongside their battery lineup, giving their customers a complete energy storage solution from brands that share the same philosophy.
