High-voltage lithium energy storage demands a chemistry that combines cycle stability with compact packaging. The Rolls R48-35LFP is a 48V 35Ah Lithium Iron Phosphate (LiFePO4) battery from the Rolls R Series, engineered for deep-cycle applications where weight savings and fast charge-discharge capability are critical operational requirements.
Manufactured by Rolls Battery Engineering under their R Series platform, this LiFePO4 cell chemistry delivers an inherently stable electrochemical structure, reducing thermal risk and supporting consistent capacity delivery across an extended service life. The 1,790Wh energy rating reflects a high energy density relative to equivalent lead-acid configurations, whilst the lithium construction reduces mass to approximately 15kg – up to 50% lighter than a comparable sealed lead-acid unit." The battery measures 260mm (L) × 180mm (W) × 273mm (H including terminal) and weighs 15kg. Terminal configuration and polarity should be confirmed directly from the product label prior to installation. No cross-reference codes are associated with this SKU. Start-stop compatibility has not been confirmed – refer to the product label for guidance. "A lower-capacity variant is available: R48-32LFP (PID000199630), offering 32Ah within the same R Series family for applications with reduced energy demands.
The Rolls R48-35LFP is covered by a 3-year manufacturer warranty, providing documented assurance of build quality and performance consistency under standard operating conditions.
