Rolls 12V 100Ah LiFePO4 Deep Cycle Battery
Internal Cold-Weather Heating & Bluetooth Telemetry — Model S12-100LFP
Engineered by Rolls Battery Engineering (Surrette Battery Company), the Rolls S12-100LFP is an industrial-grade 12.8V 100Ah Lithium Iron Phosphate (LiFePO4) deep cycle battery designed for uncompromising performance in off-grid solar cabins, RVs, commercial marine house banks, and mobile power systems.
Weighing only 26.0 lbs—less than half the weight of an equivalent lead-acid battery—the S12-100LFP features internal automatic self-heating that allows safe charging down to -20°C (-4°F), an advanced 100A continuous BMS, built-in Bluetooth monitoring for iOS and Android, and an exceptional cycle life exceeding 6,000 cycles at 80% DoD.
- 12V Bank: Up to (6) in Parallel (600Ah / 7.68kWh)
- 24V Bank: (2) in Series, up to (4) Parallel Strings
- 48V Bank: (4) in Series, up to (4) Parallel Strings (4S4P)
- Cold-Climate Internal Heating: Integrated internal heating pads automatically pre-warm the lithium cells using incoming charge current, enabling safe charging in sub-zero environments down to -20°C (-4°F).
- 6,000+ Deep Cycle Longevity: Engineered to deliver over 6,000 cycles at 80% Depth of Discharge (and 3,000+ cycles at 100% DoD), offering up to 10× the usable lifespan of conventional flooded or AGM batteries.
- Real-Time Bluetooth Monitoring: Built-in Bluetooth transmitter pairs with the dedicated Rolls mobile app (iOS & Android) for instantaneous tracking of voltage, current, state of charge (SOC), cycle count, and cell temperatures.
- Comprehensive 100A Smart BMS: Internal Battery Management System continuously protects against over-voltage, under-voltage, over-current, cell imbalance, short circuit, and high/low temperature extremes.
- Ultra-Lightweight Drop-In Architecture: Weighs just 26.0 lb (11.8 kg) in a durable IP65-rated ABS casing with integrated top handles, drastically cutting tongue weight on RVs and boats.
- Flexible Multi-Voltage Stacking: Wire up to 4 units in series for 24V or 48V power banks, and up to 4 parallel strings (4S4P for 20.48 kWh) or 6 parallel units in 12V configurations (1S6P).
- 3-Year Full Replacement Warranty: Backed by Rolls Battery Engineering with a comprehensive 3-year direct manufacturer replacement warranty.
