RELiON RB100-HP 12V 100Ah LiFePO4 Dual-Purpose Deep Cycle Starting Lithium Battery – High-Peak Power Solution for Marine, Solar, RV, and Off-Grid Systems
Elevate your starting and deep cycle needs with the RELiON RB100-HP 12V 100Ah LiFePO4 battery (Model: RB100-HP), a lightweight, Group 31-sized dual-purpose battery designed for demanding marine starting (approved for select Mercury Marine outboards), RV house power, solar, and renewable energy applications. Delivering 1280Wh of energy with a 100A continuous discharge (800A peak for 8s), this battery provides 100% usable capacity, up to 10x longer life than lead-acid, and superior low-temperature efficiency. Its advanced integrated Battery Management System (BMS) protects against overcharge, over-discharge, short circuits, and thermal extremes, ensuring safe, efficient performance in rugged environments with an IP67 waterproof enclosure. Key Features:
- Dual-Purpose High-Peak Performance: 100A continuous and 800A peak (8s) discharge, ideal for starting outboard engines, trolling motors, or powering marine electronics and solar arrays.
- Exceptional Cycle Life: Up to 3,500 cycles at 80% depth of discharge, backed by a 10-year limited warranty for superior longevity and cost savings.
- Lightweight & Efficient: Only 29.8 lbs with 99% round-trip efficiency and <3% monthly self-discharge for easy handling and minimal maintenance.
- Extreme Temperature Resilience: Discharge from -4°F to 140°F (-20°C to 60°C), charge from -4°F to 130°F (-20°C to 55°C), and store from 23°F to 95°F (-5°C to 35°C) for reliable all-season use—2.5x more efficient at low temps than lead-acid.
- Safe & Certified: UN38.3, CE, UKCA (battery), UL1642 (cells), IEC62133 (cells), and UN 3480 compliant; non-toxic LiFePO4 chemistry with no gassing or fumes for eco-friendly, indoor-safe operation.
- Rugged IP67 Enclosure: Fully waterproof and dust-tight ABS case with six M8 threaded terminals for flexible, secure, vibration-resistant connections.
- Fast Charging Capability: Up to 50A continuous (165A peak for 1 min) with low internal resistance for quick recharges, optimized for partial charges.
- Scalable & Compatible: Single battery use (no series/parallel); pairs seamlessly with Victron, Renogy, and other inverters/chargers for high-performance 12V systems.
