Rolls VB12-200LFP 12V 200Ah LiFePO₄ Battery

Key benefits

  • High-capacity 12V 200Ah LiFePO₄ battery in a standard BCI case, ideal as a drop‑in upgrade for deep‑cycle lead‑acid in leisure, marine and off‑grid systems.
  • Long service life with >6000 cycles at 80% depth of discharge and >3000 cycles at 100% DOD, significantly reducing replacement frequency.
  • Integrated hardware BMS with full protection plus Bluetooth connectivity and dedicated iOS/Android app for easy monitoring.

Brief description

The Rolls VB12-200LFP 12V 200Ah LiFePO₄ Battery (R12‑200LFP) is part of the Rolls R‑Series LFP range, using cylindrical LiFePO₄ cells in a rugged ABS enclosure. With 2.56kWh of energy, high continuous discharge current and fast-charging behaviour, it suits motorhomes, caravans, boats, commercial service vehicles and small off‑grid systems where dependable 12V storage is required. An integrated 4S200A BMS manages safety functions, while Bluetooth and the Rolls app provide clear state-of-charge and status information.

Key features

  • 12.8V nominal, 200Ah capacity and 2.56kWh total energy for larger 12V leisure and off‑grid banks.
  • Standard-size BCI ABS container with rope/plastic handles and M8 terminals for straightforward VRLA replacement.
  • Fast charge/discharge performance with up to 100A charge, 200A continuous discharge and 800A surge (300ms).
  • Wide operating temperature range and IP65 enclosure for demanding mobile and outdoor environments.
  • Configurable up to 4 units in series and 4 in parallel (4S4P at 48V) or up to 6 in parallel at 12V.
