LF4100 Compact Lithium Iron Phosphate Battery: 76.8Wh Capacity with 12V and 9V Outputs

The LF4100 represents a portable power solution designed around lithium iron phosphate (LiFePO4) chemistry, delivering a measured 76.8Wh of energy storage within a notably compact form factor. Its dimensions of 168mm by 89.2mm by 43mm make it a space-efficient choice for applications where both power capacity and physical size are considerations. This battery is engineered to provide stable DC output at three voltage levels—12V, 9V, and 5V—offering compatibility with a range of portable electronics, small instruments, and backup systems. With a specified service life exceeding 2000 full charge cycles and an operating temperature window from 0°C to +45°C, it is built for scenarios demanding reliable, repeatable power delivery over an extended period.

Features and Construction

The LF4100 battery integrates several key specifications that define its performance and practical application. Its construction centres on the LiFePO4 chemistry, known for its stability and cycle life characteristics. The product is supplied as a complete kit, ready for use with the included charging and connection accessories.

Material and Build

At its core, the LF4100 utilises lithium iron phosphate battery cells. This chemistry contributes to the product's stated capability of supporting over 2000 charge cycles, which is a quantifiable metric for long-term use. The battery is housed within a case that measures 168mm in length, 89.2mm in width, and 43mm in height, resulting in a total weight of approximately 760 grams. This combination of capacity and compact physical build allows it to serve as an integrated or external power source for mobile setups.

Size and Practical Fit

The specific external dimensions (168x89.2x43mm) and weight (~760g) are provided to help users assess the battery's physical integration into their projects or equipment. Its rectangular profile is designed for straightforward placement. The included connection cables—a DC4017 to 5521 cable and a DC5521 to 5521 cable—provide direct plug-and-play compatibility with many common DC power jacks, eliminating the need for immediate additional adaptor purchases.

Uses and Placement

With its triple-voltage output and portable form factor, the LF4100 battery addresses power needs across both occasional and regular-use scenarios. Its design parameters support deployment in various environments, provided temperature conditions are observed.

Event or Professional Use

For professional, fieldwork, or event applications, the battery's 76.8Wh capacity and 5A continuous current output can power monitoring equipment, portable lighting, communication devices, or small audio/video gear. The availability of 12V, 9V, and 5V outputs from a single unit simplifies power management for setups involving multiple devices with different voltage requirements. Its operation within a 0°C to +45°C range allows for use in many indoor and moderate outdoor conditions.

Everyday Home Use

In domestic or hobbyist contexts, this battery can serve as a backup or mobile power source for security cameras, routers, portable fans, or DIY electronics projects. The complete kit, including the 14.6V 1.5A charger, means it can be put into service immediately upon receipt. The documented cycle life indicates suitability for applications where the battery will be regularly drained and recharged, such as in a portable power bank setup for camping or vehicular use.

Benefits and Buying Value

The LF4100 offers a combination of specified performance metrics and included essentials that contribute to its practical value. The focus is on providing a ready-to-use power component with clear, measurable capabilities.

Reuse and Low Maintenance

The battery's 2000+ cycle rating is a concrete figure suggesting potential for long-term service in applications involving frequent cycling. LiFePO4 chemistry typically requires less stringent maintenance regarding full discharge compared to some other battery types. The included dedicated 14.6V 1.5A charger is matched to the battery's input requirements, promoting correct and efficient recharging to support the stated lifespan.

Why Choose This Product

This product is distinguished by its precise specifications: a 76.8Wh capacity delivered in a defined 168x89.2x43mm case, coupled with the flexibility of 12V/9V/5V outputs. The inclusion of both a suitable charger and necessary DC cables presents a complete package. For users seeking a portable DC power source with published metrics for capacity, dimensions, cycle life, and operating limits, the LF4100 provides these details upfront, allowing for an informed selection based on technical compatibility.
