Product Number: S12-135LFP
Variations
Lithium iron phosphate energy storage demands a battery management system capable of handling high cycle counts, thermal variation and sustained discharge loads without compromise. The Rolls S12-135LFP is a 12V, 135Ah LFP drop-in replacement battery from Rolls Battery Engineering, designed for commercial-grade renewable energy, marine, and off-grid applications where reliability and longevity are non-negotiable.
Built on Rolls Battery Engineering's S Series platform, the S12-135LFP advances the proven R Series LFP architecture with an integrated display screen and expanded operational controls, offering the user direct visibility of state of charge, voltage and system status. The S Series incorporates enhanced protection circuitry and additional safeguards over its predecessor, making it a technically superior option for demanding duty cycles.
The S12-135LFP measures 332mm × 171mm – 227mm (L × W × H) and weighs 15.5kg. Watt-hour capacity is rated at 1,728Wh. The battery is classified NCC Class A, confirming suitability for high-demand applications. Polarity configuration should be verified against the product label prior to installation. No direct cross-reference codes apply. Please confirm start-stop compatibility via the product label.
The S Series range extends across multiple capacities. Related variants include the S12-150LFP (150Ah), S12-200LFP (200Ah) and S12-300LFP (300Ah), all sharing the same S Series platform and management architecture.
The S12-135LFP is covered by a 5-year manufacturer warranty, providing assurance of build quality and long-term performance under normal operating conditions.
