The 48V 200Ah LiFePO4 Battery is a high-capacity energy storage workhorse, designed to meet the demands of large residential homes, small commercial buildings, and off-grid installations that require substantial power reserves. With a nominal voltage of 48V and a 200Ah capacity, it delivers an impressive total energy output of 9.6kWh (48V × 200Ah = 9600Wh)—enough to power a large home with multiple appliances (refrigerators, washing machines, HVAC systems, and electronics) for 1 to 2 days during a grid outage, or store significant amounts of energy from medium-sized solar arrays for use during peak demand hours.

LiFePO4 chemistry is the backbone of this battery’s exceptional performance. It offers a cycle life of 3000 to 5000 charge-discharge cycles at 80% DoD, which translates to 10 to 15 years of use in residential or commercial settings—far longer than the 3 to 5 years of lead-acid batteries. It also has a low self-discharge rate (less than 3% per month), meaning it retains energy for extended periods when not in use—ideal for backup systems that may sit idle for months between outages. Safety is a top priority: the battery is non-toxic, non-flammable, and highly resistant to thermal runaway, even in extreme temperatures (-20°C to 60°C), making it safe for indoor installation in garages, utility rooms, or commercial storage areas.

Performance-wise, the 48V 200Ah LiFePO4 Battery excels in both continuous and peak load scenarios. It supports a discharge rate of up to 2C, allowing it to deliver up to 400A of current (2C × 200Ah) for short periods—enough to power high-demand appliances like electric stoves, central AC units, or small commercial equipment without voltage drops. Fast charging is another key feature: most models can reach 80% charge in 2 to 3 hours using a compatible 48V high-output charger, ensuring quick replenishment after outages or heavy use. Its stable voltage output throughout the discharge cycle protects sensitive equipment, such as medical devices in small clinics or POS systems in retail stores, from damage caused by voltage fluctuations.

Design-wise, the battery features a robust, modular construction that allows for flexible installation. While it is heavier than smaller capacity models (50 to 60 kg), it can be placed on the floor (in a dedicated storage area) or mounted on racks (with optional hardware) to save space. The casing is made from durable, corrosion-resistant materials that resist dust, moisture, and physical impact, ensuring longevity in both indoor and covered outdoor environments. The built-in BMS is advanced, monitoring not just basic parameters (voltage, current, temperature) but also cell balance and SoC. It can communicate with external systems (like solar inverters or energy management software) via CANbus or RS485, enabling remote monitoring and control—ideal for users who want to track energy usage or adjust charging schedules from a smartphone or computer.

Compatibility is extensive, working with most 48V industrial and residential inverters, solar charge controllers, and backup power systems. It is an excellent choice for pairing with medium-sized solar arrays (5kW to 10kW) to maximize energy self-consumption and reduce grid reliance. For off-grid applications, such as remote farms, cabins, or construction sites, it can be combined with a large solar panel array to provide reliable, independent power. For users needing a high-capacity, long-lasting energy storage solution that balances performance, safety, and flexibility, the 48V 200Ah LiFePO4 Battery is an unparalleled choice.
