Q 1. What is the nominal voltage and capacity of the Rolls R48-35LFP?

A. The Rolls R48-35LFP operates at a nominal voltage of 48V and provides a rated capacity of 35Ah, equating to 1,790Wh of stored energy.

Q 2. What battery chemistry does the R48-35LFP use?

A. The R48-35LFP uses Lithium Iron Phosphate (LiFePO4) chemistry, which offers a thermally stable electrochemical structure, extended cycle life, and consistent capacity delivery compared to conventional lead-acid technologies.

Q 3. How does the R48-35LFP compare in weight to an equivalent lead-acid battery?

A. LiFePO4 construction allows the R48-35LFP to be up to 50% lighter than a comparable sealed lead-acid battery of equivalent voltage and capacity, reducing installation weight significantly.

Q 4. What polarity orientation does the R48-35LFP use?

A. Polarity should be confirmed directly from the label on the product. Do not assume terminal orientation without checking the label prior to installation.

Q 5. Is the Rolls R48-35LFP compatible with start-stop vehicle systems?

A. Start-stop compatibility has not been confirmed for this product. Refer to the product label and consult the manufacturer's documentation before fitting to a start-stop application.

Q 6. What is the IP rating and MCA rating for the R48-35LFP?

A. IP and MCA ratings are not applicable or have not been specified for this product. The R48-35LFP is a deep-cycle lithium energy storage battery, not a cranking battery.

Q 7. Are there alternative capacity variants available in the same Rolls R Series 48V range?

A. Yes. The R48-32LFP (PID000199630) is available as a lower-capacity variant at 32Ah within the same R Series 48V LiFePO4 family.

Q 8. What warranty does the Rolls R48-35LFP carry?

A. The Rolls R48-35LFP is covered by a 3-year manufacturer warranty, providing assurance of product quality and performance under standard operating conditions.

Q 9. What are the delivery terms for the Rolls R48-35LFP?

A. As a lithium battery, the R48-35LFP is classified as a hazardous good under ADR Class 9. Specialist hazardous goods shipping applies, with delivery typically taking 3–5 working days to UK mainland addresses. A 30-day returns policy applies.

Q 10. What are the physical dimensions and weight of the R48-35LFP?

A. The battery measures 260mm (length) × 180mm (width) × 273mm (height including terminal) and weighs 15kg.
