LF4100 12V 9V Lithium Iron Phosphate Battery: Compact 76.8Wh Power with 2000+ Cycle Life

The LF4100 is a lithium iron phosphate (LiFePO4) battery pack designed to provide portable DC power in a space-efficient format. With overall dimensions of 168mm by 89.2mm by 43mm and a weight around 760 grams, it offers a balance of capacity and portability for applications away from mains power. Its 76.8Wh energy capacity, delivered through selectable 12V, 9V, and 5V outputs, caters to a variety of equipment that operates on these common DC voltages. The inclusion of a dedicated 14.6V 1.5A charger and connection cables means it is supplied ready for use with UK 220V electrical outlets, supporting straightforward recharging between uses.

Features and Construction

The LF4100’s core specification centres on its lithium iron phosphate chemistry and compact physical build. This section details its measurable attributes and how they translate into practical application.

Material and Build

The battery utilises Lithium Iron Phosphate (LiFePO4) cell technology, a chemistry noted in the source for its specific cycle life rating of 2000+ cycles. This stated longevity figure is a key functional metric for users considering total cost of ownership and reliability over time. The construction houses this chemistry within a chassis sized at 168mm in length, 89.2mm in width, and 43mm in height, resulting in a form factor designed for integration into portable setups or as a backup power source where space is a constraint.

Size and Practical Fit

With dimensions of 168x89.2x43mm and an approximate weight of 760g, the LF4100 is a relatively lightweight and manageable power unit. This size makes it suitable for carrying in a backpack, storing in a vehicle glovebox, or positioning within a compact equipment case. The 76.8Wh capacity provides a substantive amount of energy for its physical volume, aiming to power devices for a useful duration before requiring a recharge from the supplied 14.6V 1.5A charger.

Uses and Placement

The combination of output voltages and electrical specifications defines the scenarios where the LF4100 can be effectively deployed. Its use is grounded in its technical parameters.

Event or Professional Use

For event filming, fieldwork, or professional mobile setups, the battery’s 5A continuous working current supports devices that draw power consistently within that limit, such as monitors, small amplifiers, or lighting arrays. The ability to output 12V, 9V, and 5V allows it to serve as a centralised power bank for mixed-voltage gear, potentially reducing the need for multiple individual battery packs. Operation within a 0°C to +45°C temperature range permits use in both mild and moderately warm environments.

Everyday Home Use

In domestic or hobbyist contexts, this battery can act as a portable power source for camping equipment, garden tools, or as a backup for routers and network devices during short outages. The included DC4017 to 5521 and DC5521 to DC5521 cables provide immediate connectivity options for many standard DC-powered items. Its recharging via a UK 220V outlet makes it convenient for home use, with the 2000+ cycle life indicating potential for repeated use over an extended period.

Benefits and Buying Value

The value proposition of the LF4100 stems from its stated specifications and the practical solutions they enable, without inference beyond the provided data.

Reuse and Low Maintenance

The specified 2000+ cycle life suggests the battery is engineered for numerous charge and discharge cycles, which can translate to a long service life under normal usage conditions. Lithium iron phosphate chemistry is generally associated with stable performance, contributing to a power source that requires minimal routine maintenance beyond proper charging and storage within its stated temperature limits. The complete kit—including battery, charger, and cables—means no additional purchases are necessary to begin using it with compatible equipment.

Why Choose This Product

The LF4100 may be selected for its specific combination of a compact size (168x89.2x43mm), a substantial 76.8Wh capacity, and the flexibility of three output voltages (12V/9V/5V). For users powering equipment that falls within its 5A continuous current limit and operates on these voltages, it presents a consolidated power solution. The inclusion of a matched charger and cables configured for UK outlets adds immediate utility, while the 2000+ cycle rating offers a quantifiable expectation of durability based on the source information.
