View full detailsBigBattery was founded with a simple goal: make advanced lithium battery technology accessible to everyone. What began as a small operation repurposing electric vehicle batteries has grown into a leading manufacturer of LiFePO4 energy storage solutions designed for solar, backup power, RV, marine, and off-grid systems.
BigBattery’s mission is to deliver safe, long-lasting, and cost-effective battery systems that help customers achieve greater energy independence. Their lineup includes high-capacity lithium battery banks, rack-mounted server batteries, and modular energy storage systems engineered for reliability and easy expansion. Popular models like the Kong Elite, Husky, and 48V server rack batteries provide dependable performance for homeowners, installers, and off-grid enthusiasts looking to store more power and reduce reliance on traditional energy sources.
BigBattery batteries are designed for a wide range of energy storage applications, including home backup power, off-grid living, solar energy storage, RVs, campers, boats, and commercial or industrial systems. Built with lithium iron phosphate (LiFePO4) technology, they provide reliable, long-lasting power and can be used as standalone battery banks or integrated with inverters and solar panels. Their modular designs make them suitable for everything from small recreational setups to large-scale energy storage systems.
Yes, depending on the size of the system and your household's energy requirements. BigBattery offers energy storage solutions capable of powering essential appliances during outages or supporting whole-home backup when paired with compatible inverters and transfer equipment. The amount of backup time and the number of appliances that can be powered depend on the battery capacity, power output, and your overall energy consumption.
Yes. BigBattery batteries are well-suited for off-grid homes, cabins, RVs, and mobile applications because they provide dependable energy storage, deep discharge capability, and long cycle life. Their LiFePO4 chemistry offers greater efficiency and lower maintenance compared to traditional lead-acid batteries. Many users pair them with solar panels to create self-sufficient power systems for extended travel or remote living.
Choosing the right system starts with determining what you want to power and how long you need backup power. Consider your daily energy consumption, the wattage requirements of your appliances or equipment, and whether you plan to use solar panels. Smaller systems may be sufficient for RVs and essential home circuits, while larger battery banks are better suited for whole-home backup or commercial applications. Expandability, inverter compatibility, and available installation space should also be taken into account when selecting a system.
Yes. BigBattery batteries are commonly used with solar energy systems and can store excess electricity generated during the day for use at night or during power outages. When paired with compatible charge controllers and inverters, they help maximize solar energy usage and provide greater energy independence. This makes them an excellent solution for homeowners, off-grid users, RV owners, and businesses looking to reduce reliance on the electrical grid.
Many BigBattery systems are designed with scalability in mind, allowing users to add additional battery capacity as their energy needs grow. This flexibility makes them suitable for a variety of applications, from small backup systems to larger residential and commercial energy storage installations. Expandable designs also make it easier to future-proof your investment without replacing your entire system.
BigBattery batteries use lithium iron phosphate (LiFePO4) technology, which is known for its long lifespan and durability. Depending on the model and operating conditions, many batteries are capable of delivering thousands of charge cycles and can provide reliable performance for 10 years or more. Proper installation, charging practices, and routine maintenance can help maximize battery life and ensure long-term value.
LiFePO4 batteries offer several advantages over traditional lead-acid batteries, including longer lifespan, faster charging, higher energy efficiency, lighter weight, and improved safety. They can withstand deeper discharge cycles without significant performance loss and require very little maintenance. These benefits make BigBattery systems an attractive choice for home backup, solar storage, RVs, marine applications, and industrial use.
Yes. BigBattery offers energy storage solutions that are suitable for a variety of commercial and industrial applications, including backup power, telecommunications, warehouses, agricultural operations, and renewable energy systems. Their high-capacity lithium battery systems provide scalable and reliable energy storage that can help improve resilience and support critical operations during power interruptions.
For many homeowners, RV owners, off-grid users, and businesses, BigBattery systems can be a worthwhile investment. Their LiFePO4 technology provides long cycle life, high efficiency, low maintenance requirements, and the flexibility to expand as energy needs increase. While the initial cost may be higher than traditional lead-acid batteries, the longer lifespan and improved performance often result in greater value over time.
