BigBattery is the leading environmental battery manufacturer in the United States, as well as the only Carbon-Neutral battery manufacturer offering sustainable power globally.
BigBattery exists to make clean energy accessible to everyone. We identified the #1 barrier to renewable energy adoption: the high cost of battery storage. Our mission is to solve that through smarter design, domestic manufacturing, and industry leading pricing.
We design products for longevity, not planned obsolescence. Our batteries feature modular, hot-swappable components with no proprietary parts because we believe in the right to repair. Simple to install, simple to maintain, built to outlast the competition.
