The 51.2V 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 51.2V and a 200Ah capacity, it delivers an impressive 10.24kWh of total energy (51.2V × 200Ah = 10240Wh)—enough to power a large home with multiple appliances (refrigerators, washing machines, HVAC systems) for 1 to 2 days during a grid outage, or store significant amounts of solar energy for use during peak demand periods, maximizing savings on electricity bills.

LiFePO4 chemistry is the backbone of this battery’s performance, offering unmatched durability and safety. It boasts a cycle life of 3000 to 5000 cycles at 80% DoD, meaning it can last 10 to 15 years in residential use—far longer than lead-acid batteries (which typically last 3 to 5 years). It also has a low self-discharge rate (less than 3% per month), so it retains energy for extended periods when not in use—ideal for backup systems that may sit idle for months between outages. Unlike lead-acid batteries, it is non-toxic, non-flammable, and resistant to thermal runaway, making it safe for indoor installation (like garages or utility rooms) without the risk of acid leaks or toxic fume emissions.

Performance-wise, the battery excels in both continuous and peak load scenarios. It supports a discharge rate of 1C 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 commercial equipment without voltage drops. It also enables fast charging, with most models reaching 80% charge in 2 to 3 hours using a compatible 51.2V high-output charger, ensuring quick replenishment after a power outage or heavy use. Its stable voltage output throughout the discharge cycle protects sensitive electronics, such as home automation systems or medical equipment, from damage caused by voltage fluctuations.

Design-wise, it features a robust, modular construction that allows for flexible installation. While it is heavier than smaller capacity models (60 to 70 kg), it can be placed on the floor (in a dedicated storage area) or mounted on walls (with optional heavy-duty brackets) to save space. The casing is made from durable, fire-retardant materials that resist impact, dust, and moisture, 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 communicates with external systems (like solar inverters or home 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 51.2V solar inverters (including hybrid inverters that combine solar, grid, and battery power) and charge controllers from leading brands. It is also suitable for off-grid applications, such as remote cabins, farms, or vacation homes, where it can be paired 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 51.2V 200Ah LiFePO4 Battery is an exceptional choice.
