LiFePO4 51.2V 200 Ah Rechargeable Battery is a reliable, safe, and durable power source for stationary and autonomous systems. This lithium iron phosphate battery, with a nominal voltage of 51.2 V and a capacity of 200 Ah, provides an energy capacity of 10.24 kWh and is designed for an operating life of approximately 6000 full cycles (at 80% DOD, 25 °C), allowing for an expected service life of up to 10 years. The battery is suitable for systems with high energy consumption, compatible with various types of inverters, and supports charging from solar panels, making it an efficient and environmentally friendly solution for home, office, or industrial installations.

The model is equipped with a built-in battery management system (BMS) that monitors charge, voltage, and current, provides protection against overload, overheating, and short circuits, and allows connection to a computer for real-time monitoring and remote software updates. Thanks to its low self-discharge rate, the battery retains its charge for a long time, and the absence of heavy metals enhances environmental friendliness during operation.

Frequently Asked Questions

Below are answers to common questions about LiFePO4 batteries and the operation of the specific 51.2V 200 Ah model.

How do lithium iron phosphate batteries differ from conventional lithium-ion batteries?

Lithium iron phosphate batteries use a different cathode material — lithium iron phosphate, which provides a more stable chemical structure, higher safety, less susceptibility to overheating and ignition, and a significantly greater number of operating cycles (thousands of cycles instead of a few hundred).

What are the disadvantages of LiFePO4 compared to other lithium-ion batteries?

Disadvantages include lower energy density (bulkier solutions for the same capacity), sensitivity to extremely low temperatures, and a higher initial cost, but these are offset by durability and safety.

How long will a 200 Ah battery last under a 100 W load?

Under a 100 W load, this battery can theoretically operate for up to approximately 4 days, although the actual time depends on operating conditions, temperature, and system efficiency.

How to extend battery life?

Recommendations: avoid full discharge, use quality chargers, do not operate at extreme temperatures, store partially charged (~50%) for long-term storage.

This model is ideal for backup power systems, autonomous solar stations, commercial, and industrial applications where high cyclability, safety, and scalability are required.
