Deep-cycle and traction applications demanding a dependable 36-volt lithium power source require a battery that balances energy density with long service life. The Rolls R36-52LFP is a 36V 52Ah Lithium Iron Phosphate (LiFePO4) battery from the Rolls R Series, delivering 2000Wh of usable energy within a compact 330 × 173 × 219 mm footprint and a manageable 16.5 kg weight – up to 50% lighter than a comparable sealed lead-acid unit.
Engineered by Rolls Battery Engineering under their R Series programme, this LiFePO4 cell chemistry offers a stable discharge curve, inherently safer thermal characteristics than alternative lithium chemistries, and fast charge acceptance. The R Series platform supports series connectivity up to 48V, making the R36-52LFP suitable for electric mobility, material handling, and off-grid energy storage applications where space and weight are constraints." The battery measures 330 mm (L) × 173 mm (W) × 219 mm (H) including terminals. Terminal configuration and polarity should be verified against the product label prior to installation. No CCA or MCA rating applies; this unit is not confirmed for start-stop duty. There are no published cross-reference codes for this SKU. "Two higher-capacity variants are available within the same R Series 36V range: the R36-60LFP (60Ah) and the R36-65LFP (65Ah), each sharing the same platform architecture.
The Rolls R36-52LFP is covered by a 3-year manufacturer warranty, providing assurance of build quality and electrochemical performance over the intended service period.
