Deep-cycle and standby power applications demand a battery that can deliver consistent capacity across repeated charge cycles without the weight and maintenance penalties of traditional lead-acid chemistry. The Rolls Battery Engineering R12-100LFP is a 12V 100Ah Lithium Iron Phosphate (LiFePO4) battery designed as a direct drop-in replacement for sealed lead-acid units in a wide range of renewable energy, marine auxiliary, and mobility applications.
Engineered under Rolls Battery Engineering's R Series platform, this cell chemistry uses LiFePO4 technology to deliver stable discharge voltage, high cycle life, and a 1280Wh energy capacity within a compact housing. The R Series is designed to support up to 48V system connectivity through series configuration, and the lithium construction saves up to 50% in weight compared to equivalent SLA batteries, with a confirmed mass of 11.5kg." The R12-100LFP measures 260mm (L) × 170mm (W) × 211mm (H) including terminals. No cross-reference codes are listed for this model. Polarity configuration should be confirmed directly from the product label prior to installation. Start-stop vehicle compatibility has not been confirmed for this unit – refer to the product label for guidance. No case type or terminal specification data is held on record. No additional variants are available for this SKU. Similar lithium batteries within the Rolls R Series range include models available in 12V and 24V configurations across differing capacities; see related products for details. "The R12-100LFP is backed by a 3-year manufacturer warranty, providing documented assurance of performance and build quality over the expected service period.
