Trusted by more than 5,000 homeowners across the United States, BigBattery lithium batteries are built to deliver consistent power during outages, daily solar cycling, or independent off-grid operation. With a cycle life rated at 6,000+ cycles, they help reduce lifetime cost per kWh over extended use, particularly when compared with lower-cycle battery technologies.
LiFePO4 (Lithium Iron Phosphate)
Designed with extended cycle life, thermal stability, and operational safety in mind. A reliable choice for daily solar storage, whole-home backup when paired with appropriate capacity and inverter configuration, and long-term off-grid power systems.
NMC (Nickel Manganese Cobalt)
High energy density in a compact footprint. Designed for installations with limited space or short-duration backup where fast response and size efficiency matter.
Small - 6–10 kWh
Supports essential household loads such as refrigeration, lighting, routers, and basic electronics for up to 2–3 days, depending on usage.
Medium - 10–15 kWh
Provides extended coverage for larger living areas, home offices, or short-term whole-room backup during grid outages.
All BigBattery units use a 48V lithium architecture, ensuring efficient power delivery, reduced current losses, and straightforward integration with most residential, hybrid, and solar-ready inverters used in the U.S. market.
