Q 1. What is the nominal voltage and capacity of the Rolls R48-90LFP?

A. The Rolls R48-90LFP operates at a nominal voltage of 48V and has a rated capacity of 90Ah measured at the C20 discharge rate.

Q 2. What battery chemistry does the R48-90LFP use?

A. The R48-90LFP uses Lithium Iron Phosphate (LiFePO4) chemistry, which provides inherent thermal stability, a long cycle life, and fast charge acceptance compared to conventional sealed lead-acid batteries.

Q 3. What applications is the Rolls R48-90LFP suitable for?

A. This battery is designed for deep-cycle applications including off-grid solar storage, renewable energy systems, electric vehicles, and industrial power applications requiring high-capacity 48V lithium energy storage.

Q 4. What are the physical dimensions and weight of the R48-90LFP?

A. Physical dimensions and weight are not published in the current product data. Buyers requiring this information should contact PartsForMachines directly before placing an order.

Q 5. What terminal type and polarity orientation does the R48-90LFP use?

A. Terminal type and placement specifications are not confirmed in the published data. Polarity should be verified by reference to the label on the battery itself prior to installation.

Q 6. Does the Rolls R48-90LFP have a Cold Cranking Amps (CCA) or Marine Cranking Amps (MCA) rating?

A. No CCA or MCA rating is published for this model. The R48-90LFP is a deep-cycle LiFePO4 battery and is not rated for engine cranking applications.

Q 7. What is the Watt-Hour (Wh) energy capacity of the R48-90LFP?

A. A Watt-Hour figure is not published in the current product data. As a general reference, a 48V 90Ah battery has a theoretical energy content of approximately 4,320Wh, though actual usable capacity will depend on depth of discharge settings within the battery management system.

Q 8. Are there alternative variants available in the Rolls 48V LiFePO4 range?

A. Yes. Related variants include the Rolls R48-105LFPEV-LFPA (PID000199633) and the R48-105EV-LFP-B (PID000199634), which offer alternative capacity or application configurations within the 48V LiFePO4 platform.

Q 9. What warranty does the Rolls R48-90LFP carry?

A. The R48-90LFP is supplied with a 3-year manufacturer warranty covering defects in materials and workmanship under normal operating conditions.

Q 10. What are the delivery terms for the Rolls R48-90LFP?

A. As a lithium battery, the R48-90LFP is classified as ADR Class 9 hazardous goods. Specialist hazardous goods shipping applies. Delivery is typically 3–5 working days within UK mainland. A 30-day returns policy applies.
