Product Description

The Dayliff 100AH LiFePO4 Lithium Ion Battery with integrated BMS is a high‑performance, deep‑cycle energy storage solution engineered for solar power systems, off‑grid applications, backup power and mobile power needs. Built on advanced Lithium Iron Phosphate (LiFePO4) cell technology, this battery offers a significant upgrade over traditional lead‑acid alternatives — delivering greater longevity, better efficiency, and improved safety.

With a nominal capacity of 100 Ah and a nominal voltage of approximately 12.8 V, the Dayliff 100AH LiFePO4 battery provides roughly 1,280 Wh of usable energy in a compact, lightweight package that’s typically about a third of the weight of a comparable lead‑acid unit.

A key feature is the built‑in Battery Management System (BMS). This intelligent circuitry continuously monitors and regulates the battery’s internal cells to protect against over‑charging, over‑discharging, over‑current, short circuits and temperature extremes, all of which help extend lifespan and ensure reliable operation.

The LiFePO4 chemistry delivers a very long cycle life — commonly exceeding 3,000 to 5,000 full charge/discharge cycles at 80 % depth of discharge — which is significantly longer than typical lead‑acid batteries. This translates to years of dependable service with minimal maintenance and lower total cost of ownership.

Designed to be maintenance‑free, the battery features sealed construction with no liquid electrolytes, eliminating issues like acid leaks and gassing. Its low self‑discharge rate (~3 % per month) means it holds charge well during periods of infrequent use, making it ideal for seasonal off‑grid systems or backup power scenarios.

The compact form factor and relatively light weight make the Dayliff 100AH LiFePO4 an excellent choice for a wide range of applications, including solar home installations, inverters, UPS systems, RVs, marine use, caravans and remote cabins. Multiple units can also be connected in parallel (and in series where applicable) to increase capacity or system voltage for larger setups.

Overall, the Dayliff 100AH LiFePO4 Lithium Ion Battery C/W BMS combines enhanced safety, extended life, high performance and versatile installation options, offering a modern energy storage solution suited to today’s renewable energy and backup power demands.
