Product Number: S12-300LFP
Variations
Deep-cycle lithium iron phosphate applications demand a battery that combines high energy density with intelligent battery management, and the Rolls S12-300LFP delivers precisely that. Part of the Rolls Battery Engineering S Series, this 12V 300Ah LFP unit is engineered as a drop-in replacement for conventional lead-acid deep-cycle batteries across renewable energy storage, marine, motorhome, and off-grid applications.
Built on Rolls Battery Engineering's established lithium iron phosphate platform, the S Series advances beyond the R Series by incorporating an integrated display screen with direct control interface, offering real-time monitoring of state of charge, voltage, and system status. The LFP chemistry provides a stable discharge curve, inherent thermal stability, and a significantly longer cycle life compared to AGM or gel alternatives.
The S12-300LFP measures 522mm × 268mm – 240mm and weighs 34kg, delivering 3,840Wh of usable energy. Terminal configuration and polarity should be verified on the product label prior to installation. No direct cross-reference codes are currently confirmed for this model. Start-stop compatibility is not confirmed – refer to the product label.
The S Series 12V LFP range also includes the S12-135LFP, S12-150LFP, and S12-200LFP, allowing system designers to select the capacity that best matches their load and autonomy requirements.
This battery is backed by a 5-year manufacturer warranty from Rolls Battery Engineering, reflecting the quality and durability expected from the Series 5000 product group.
Delivery: hazardous goods shipping applies, typically 3–5 working days within UK mainland. 30-day returns.
Rolls Series 5000 Deep Cycle Batteries - Rolls have been manufacturing batteries for over 60 years and have built a reputation on reliability, durability and easy maintenance of its product. The series 5000 all have a dual container construction and the high-density polyethylene material maximizes durability and eliminates acid leaks even if the outer container ruptures. The unique 'resistor' plate design offers more resistance to corrosion and maximizes the life of the battery. The life expectancy of Rolls 5000 batteries are amongst the longest in the industry.
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.
