LF4100 Compact 12V/9V Lithium Iron Phosphate Battery with 76.8Wh Capacity

The LF4100 is a lithium iron phosphate (LiFePO4) battery designed to provide portable, multi-voltage DC power in a space-efficient form. Measuring just 168mm x 89.2mm x 43mm and weighing approximately 760g, it packs a 76.8Wh capacity, making it a practical power source for a range of portable electronics, hobbyist projects, or backup applications where its small volume is a key advantage. It delivers three standard output voltages: 12V, 9V, and 5V, offering compatibility with various devices that require these common DC levels. Supplied with a dedicated 14.6V/1.5A charger and connection cables, it is ready for use straight from the box.

Features and Construction

The LF4100 is built around lithium iron phosphate chemistry, a battery type noted for its stability and cycle life. Its design prioritises a compact footprint and multi-voltage output capability, supported by specified operational parameters.

Material and Build

The battery utilises lithium iron phosphate (LiFePO4) cells. This chemistry is associated with a robust cycle life, which aligns with the product's specified service life of 2000+ charge cycles. The construction houses these cells, the necessary management circuitry, and output ports within the stated dimensions.

Size and Practical Fit

With external dimensions of 168mm in length, 89.2mm in width, and 43mm in height, the battery has a small volume profile. Its approximate weight of 760g contributes to its portability. This compact size allows it to fit into tight spaces within equipment cases, vehicles, or as part of custom installations where a discreet power source is needed.

Uses and Placement

The combination of 12V, 9V, and 5V outputs, coupled with its portable size, makes the LF4100 suitable for a variety of power applications outside of a fixed mains supply.

Event or Professional Use

For professional, event, or field use, this battery can power portable lighting, monitoring equipment, small amplifiers, or data loggers that operate on its available voltages. Its operational temperature range of 0°C to +45°C allows for use in many indoor and sheltered outdoor environments. The 5A continuous working current supports devices with moderate power demands.

Everyday Home Use

Around the home, workshop, or for hobbies, the LF4100 can serve as a power bank for routers during outages, a source for model railways or robotics, or for charging other USB-compatible devices via appropriate adapters (using the 5V output). Its included cables (DC4017 to 5521 and DC5521 to 5521) facilitate connection to many standard DC ports.

Benefits and Buying Value

The value of the LF4100 stems from its specific technical offering: multi-voltage output, substantial capacity for its size, and a long cycle life, all presented with the necessary accessories for immediate use.

Reuse and Low Maintenance

The stated 2000+ cycle service life indicates the battery can be recharged and used many times over its lifespan. LiFePO4 chemistry typically requires less stringent maintenance regarding discharge levels compared to some other battery types, though following the provided usage guidelines is recommended. The included charger is matched to the battery's 14.6V input specification.

Why Choose This Product

Choose the LF4100 if you require a compact, self-contained DC power source with the flexibility of 12V, 9V, and 5V outputs. Its 76.8Wh capacity and 2000+ cycle rating offer a balance of power and longevity. The complete package, including charger and cables, provides a functional solution for powering portable devices where space is limited and specific voltages are needed.
