Product Number: R12-450LFP
Variations
High-capacity energy storage in deep-cycle and off-grid applications demands a battery technology that can sustain repeated charge and discharge cycles without capacity degradation. The Rolls R12-450LFP is a 12V 450Ah Lithium Iron Phosphate (LiFePO4) battery from the Rolls R Series, engineered for commercial-grade stationary, marine, and renewable energy installations where energy density, cycle life, and reliable discharge performance are critical requirements.
Manufactured by Rolls Battery Engineering, the R Series LiFePO4 platform employs lithium iron phosphate chemistry to deliver a stable, thermally resilient cell architecture. With a rated energy capacity of 5,760Wh, the R12-450LFP supports fast charge and discharge capability while remaining up to 50% lighter than comparable sealed lead-acid alternatives. The chemistry is inherently more stable than other lithium variants, making it a technically sound choice for sustained energy applications.
The R12-450LFP measures 521mm × 267mm – 220mm (L × W × H), providing a compact footprint suited to multi-battery bank configurations with connectivity up to 48V. Terminal type and polarity should be confirmed directly from the product label prior to installation. No direct cross-reference codes are available for this unit. Cold cranking amps and NCC classification are not applicable for this battery type.
The R Series range is available in multiple capacities to suit varying system demands. Related variants include the R12-135LFP, R12-150LFP, R12-200LFP, and R12-300LFP, all sharing the same LiFePO4 platform.
The Rolls R12-450LFP is covered by a 3-year manufacturer warranty, providing assurance of build quality and consistent performance across its intended service life.
Delivery: hazardous goods shipping applies, typically 3–5 working days within UK mainland. 30-day returns.
Rolls Series 4000 Deep Cycle Batteries - The Rolls series 4000 batteries are available in 2V, 6V or 12V configuration and offer a wide range of capacities. Used in a variety of applications including renewable energy systems, they have a long life expectancy and one of the longest warranty periods available.
Combination of thick plate design with the highest density active material. Envelope separators. Increased electrolyte reserve. Greater rigidity. Greater durability. Sediment chamber removed allowing higher plates to be used in the same sized cell, thus yielding greater capacity. Unsurpassed cycling service. Less maintenance.
Key Feature:Built for industrial and construction machinery, supplying consistent power output and resilience to meet demanding start-stop and auxiliary power needs in tough operating conditions.
