The 51.2V 100Ah LiFePO4 Battery is a versatile, mid-capacity energy storage solution designed for a wide range of applications, including residential solar systems, small commercial backup setups, and off-grid projects like tiny homes or RVs. With a nominal voltage of 51.2V and a 100Ah capacity, it delivers 5.12kWh of total energy (51.2V × 100Ah = 5120Wh)—enough to power essential home appliances (lights, refrigerators, small HVAC units) for 8 to 10 hours during an outage, or store excess solar energy for evening use, reducing reliance on the grid.

A key benefit of this battery is its LiFePO4 chemistry, which offers a superior alternative to traditional lead-acid batteries. It has a cycle life of 3000 to 5000 cycles at 80% DoD, translating to 8 to 12 years of use in residential settings—more than double the lifespan of lead-acid batteries. It also requires no maintenance, eliminating the need for regular water refilling or acid checks, and is inherently safer: its high thermal stability resists overheating and thermal runaway, making it suitable for indoor installation (like garages or utility rooms) without the risk of toxic fume emissions.

In terms of performance, the battery delivers consistent power across its discharge cycle. It supports a discharge rate of 1C to 1.5C, meaning it can release its full 100Ah capacity in 40 to 60 minutes—fast enough to handle sudden power demands from appliances like microwaves or small power tools. It also enables fast charging, with most models reaching 80% charge in 1 to 2 hours using a compatible 51.2V charger, ensuring quick replenishment after use. Unlike lead-acid batteries, it maintains a stable voltage throughout discharge, preventing dips that can damage sensitive electronics like smartphones or laptops.

Design-wise, it features a compact, portable form factor (typically 30 to 40 kg) that makes it easy to install in a variety of locations—whether placed on a shelf, in a storage cabinet, or mounted (with optional brackets) for space efficiency. The casing is made from durable, fire-retardant plastic that protects internal components from dust, moisture, and minor impacts. The built-in BMS is a critical component, continuously monitoring voltage, current, temperature, and SoC. It prevents overcharging (a common risk with solar systems), over-discharging (which can shorten battery life), and short-circuiting, while also balancing cell voltages to ensure uniform performance across all cells.

Compatibility is a strong suit, as it works with most 51.2V solar inverters, charge controllers, and backup power systems. It is also compatible with off-grid setups, such as RVs or tiny homes, where it can be paired with a small solar panel array to provide reliable power on the road or in remote locations. For users seeking a balance of capacity, portability, and longevity, the 51.2V 100Ah LiFePO4 Battery is a versatile, cost-effective solution that meets the needs of both residential and small commercial applications.
