Q 1. What is the nominal voltage and capacity of the Rolls R24-50LFP?

A. The Rolls R24-50LFP operates at a nominal voltage of 24V with a rated capacity of 50Ah (C20), equating to 1,280Wh of stored energy.

Q 2. What cell chemistry does the R24-50LFP use?

A. This battery uses Lithium Iron Phosphate (LiFePO4) chemistry, which offers stable discharge performance, a long cycle life, and improved thermal stability compared with standard lithium-ion or lead-acid technologies.

Q 3. What are the physical dimensions and weight of the R24-50LFP?

A. The battery measures 260mm (L) × 170mm (W) × 211mm (H, including terminal) and weighs 12kg, making it significantly lighter than an equivalent-capacity lead-acid battery.

Q 4. Can the R24-50LFP replace a sealed lead-acid or AGM battery directly?

A. Rolls describe the R Series as a compatible drop-in SLA replacement. However, buyers should verify that their charging system is compatible with LiFePO4 charge profiles before installation, as SLA chargers may not be suitable.

A. Start-stop compatibility has not been confirmed for this SKU. Refer to the product label and consult Rolls Battery Engineering or a qualified installer before using this battery in a start-stop application.

Q 7. Can multiple R24-50LFP batteries be connected in series to achieve higher voltages?

A. Yes. The Rolls R Series is designed to support series connectivity up to 48V, allowing two 24V units to be combined where higher voltage systems are required. Always follow Rolls Battery Engineering installation guidelines.

Q 8. What is the IP rating and MCA rating of the R24-50LFP?

A. An IP ingress protection rating and Marine Cranking Amps (MCA) figure are not applicable or not specified for this battery. It is not classified as a cranking battery.

Q 9. What warranty does the Rolls R24-50LFP carry?

A. The R24-50LFP is covered by a 3-year manufacturer warranty from Rolls Battery Engineering, covering defects in materials and workmanship under normal operating conditions.
