LF4100 12V Lithium Iron Phosphate Battery with 9V and 5V Outputs for Portable Power

The LF4100 is a high-capacity, portable Lithium Iron Phosphate (LiFePO4) battery designed to provide reliable DC power for a variety of electronic devices and systems. Its compact form factor, measuring 168mm in length, 89.2mm in width, and 43mm in height, and weighing just 760g, makes it an excellent choice for applications where space and weight are considerations, such as in mobile CCTV setups, portable lighting, camping equipment, or as a backup power source. With a substantial 76.8Wh energy capacity and the ability to output 12V, 9V, and 5V, this unit serves as a versatile power bank for many common low-voltage gadgets and professional tools that require stable, long-lasting energy away from a mains supply.

Features and Construction

The LF4100 battery pack integrates key specifications that define its performance and practical application. It is built around a robust Lithium Iron Phosphate chemistry, which contributes to its stated long-term service life and stable power delivery. The following sections detail the core aspects of its build and functionality.

Material and Build

At the heart of this power supply is a Lithium Iron Phosphate (LiFePO4) cell. This chemistry is recognised for its inherent thermal stability and long cycle life, which directly supports the product's claim of over 2000 charge cycles. The internal construction is housed within a casing that results in the given dimensions, creating a solid and portable unit. The electrical design supports a continuous output current of 5A, ensuring it can handle sustained power demands from connected devices without interruption.

Size and Practical Fit

The physical profile of the LF4100 is a major practical advantage. Its dimensions of 168mm x 89.2mm x 43mm allow it to fit comfortably in bags, cases, or mounted within equipment racks. The approximate weight of 760g means it adds minimal burden to a mobile setup. This small volume, combined with the 76.8Wh capacity, offers a favourable energy density, providing substantial power without the bulk often associated with lower-tech battery solutions.

Uses and Placement

This battery's combination of voltage outputs, capacity, and portability opens it up to a wide array of uses in both professional and personal contexts. Its operating temperature range of 0°C to +45°C further defines the environments where it can be reliably deployed.

Event or Professional Use

For professional applications, the LF4100 is well-suited as a power source for portable CCTV cameras, monitoring equipment, or field measurement devices that operate on 12V, 9V, or 5V DC. The included DC5521 and DC4017 cables facilitate direct connection to many professional video and data acquisition units. Its ability to deliver a continuous 5A current supports equipment that requires consistent power over several hours, making it a practical choice for security personnel, event videographers, or surveyors working off-grid.

Everyday Home and Outdoor Use

Beyond professional settings, this battery serves as a capable portable power station for leisure and home use. It can power or recharge portable fans, LED camping lights, small air pumps, or USB-powered devices (with an appropriate adapter for the 5V output). Its rugged LiFePO4 construction and long cycle life make it a reliable companion for weekend camping trips, fishing excursions, or as an emergency backup for essential communication devices during power outages.

Benefits and Buying Value

The value proposition of the LF4100 battery lies in its specific technical attributes that translate into practical user benefits. It is designed not as a generic power bank, but as a targeted solution for low-voltage DC power needs.

Reuse and Low Maintenance

The quoted service life of 2000+ charge cycles is a core benefit, indicating that the battery can be recharged and used hundreds of times before significant capacity degradation. This longevity reduces the frequency of replacement compared to batteries with shorter lifespans, offering better long-term value. The included 14.6V/1.5A charger with a US 220V plug provides a complete charging solution, minimising the need for additional purchases to start using the product immediately.

Why Choose This Product

Choosing the LF4100 is justified by its specific blend of compact size, multi-voltage output, and high cycle life. For users seeking a portable 12V power source that can also provide 9V and 5V, this product eliminates the need for multiple single-voltage batteries or bulky voltage converters. The full package, which includes the necessary charger and connection cables, offers a ready-to-use system. Its operational temperature range ensures it performs reliably in most indoor environments and many temperate outdoor conditions, providing a practical power solution for defined, real-world applications.
