48V Lithium Batteries

48V Lithium Batteries from Epoch

48 volts has become the dominant voltage for modern solar energy storage, home backup systems, golf carts, and commercial off-grid installations. Higher voltage means lower current draw, smaller cable sizes, and better efficiency than 12V or 24V banks. Every Epoch Batteries 48V LiFePO4 battery is backed by an industry-leading 11-year warranty and 100% US-based support from Atlanta, Georgia.
