Product Number: R12-150LFP
Variations
Deep-cycle and renewable energy applications demand a battery that combines high usable capacity with tolerance for repeated charge and discharge cycles – conditions that traditional sealed lead-acid units handle poorly over time. The Rolls R12-150LFP addresses this directly as a purpose-engineered Lithium Iron Phosphate (LiFePO4) drop-in replacement for 12V SLA installations, offering 150Ah of rated capacity and 1,920Wh of stored energy within a compact, lightweight enclosure.
Rolls Battery Engineering's R Series LiFePO4 chemistry delivers stable voltage output across the discharge curve, rapid charge acceptance, and a significantly extended cycle life compared with conventional lead-acid technology. The cell chemistry is inherently more thermally stable than other lithium formulations, reducing risk in enclosed installations. The design supports up to 48V system connectivity, making it scalable for larger off-grid or backup power configurations." The R12-150LFP measures 330mm × 173mm – 219mm (L × W × H) and weighs 15.5kg – up to 50% lighter than an equivalent SLA unit. Voltage is 12V nominal. Terminal type and polarity should be confirmed on the product label prior to installation. No direct cross-reference codes are listed for this SKU; fitment compatibility should be verified against your application's physical and electrical requirements. "This product is available in a range of capacities within the Rolls R Series LiFePO4 lineup, including R12-135LFP, R12-200LFP, R12-300LFP, and R12-450LFP, allowing system designers to select the most appropriate energy storage for their load profile.
The R12-150LFP is covered by a 3-year manufacturer's warranty, providing assurance of build quality and performance consistency throughout the warranty period.
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.
