Product Description

The Dayliff 75AH LiFePO4 Lithium Ion Battery with integrated Battery Management System (BMS) is a high‑performance energy storage solution designed for modern solar systems, off‑grid power applications, backup power supply and deep‑cycle use. Built on Lithium Iron Phosphate (LiFePO4) chemistry, this battery offers superior safety, long service life, and outstanding performance compared with traditional lead‑acid batteries — making it a reliable choice for both residential and commercial power storage needs.

Rated at approximately 12.8 volts and 75 amp‑hours, the battery delivers around 960 Wh of usable energy, providing stable and consistent DC power for inverters, lighting, telecommunications equipment, and solar systems. LiFePO4 cells are known for their high thermal and chemical stability, which significantly reduces the risk of overheating, combustion, or leakage — a key safety advantage over other lithium‑ion technologies.

A built‑in Battery Management System (BMS) is central to the battery’s performance and longevity. The BMS provides real‑time protection and intelligent control, safeguarding the battery from over‑charge, over‑discharge, over‑current, short‑circuit, and extreme temperature conditions. It also balances individual cells to prevent cell mismatch and improves overall durability.

The LiFePO4 battery is lightweight and compact compared to equivalent lead‑acid units, with a typical Group‑24 footprint that fits many standard battery enclosures and racks. It also supports parallel connections — allowing multiple batteries to be linked together for expanded capacity in larger power systems.

With an impressive cycle life of over 5,000 charge/discharge cycles at 80 % depth of discharge (DOD), this battery outlasts conventional alternatives by a wide margin, translating to lower replacement costs over time and better return on investment. It also maintains a low self‑discharge rate (around 3 % per month), meaning stored energy is preserved over long periods of standby use.

The unit is engineered to operate across a broad temperature range and is suitable for solar, backup, and off‑grid applications where reliable, rugged performance is essential. Combined with its maintenance‑free design and high energy density, the Dayliff 75AH LiFePO4 Battery with BMS offers a modern, efficient, and safe energy storage solution for homes, remote systems, and power‑backup installations.
