RELiON RB300-HP 12V 300Ah LiFePO4 High-Performance Deep Cycle Lithium Battery – Extreme Power Solution for Marine, Solar, RV, and Off-Grid Systems
Elevate your high-demand energy needs with the RELiON RB300-HP 12V 300Ah LiFePO4 battery (Model: RB300-HP), a lightweight, Group 8D-sized high-performance deep cycle battery engineered for the most demanding marine (including sailboats and catamarans), solar, RV, and renewable energy applications. Delivering 3840Wh of energy with a 100A continuous discharge and an ultra-high 800A peak for 2s, this battery provides 100% usable capacity, up to 10x longer life than lead-acid, and superior low-temperature efficiency (2.5x more efficient than lead-acid at low temps). 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 IP66-rated enclosure. Key Features:
- High-Performance Power: 100A continuous and 800A peak (2s) discharge, ideal for high-drain marine equipment, trolling motors, starting service, or solar arrays with constant power throughout discharge.
- 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 82.7 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 113°F (-20°C to 45°C), and store from 23°F to 95°F (-5°C to 35°C) for reliable all-season use.
- Safe & Certified: UN38.3, UKCA, CE (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 IP66 Enclosure: Dust-tight and water-resistant ABS case with M8 threaded terminals for secure, vibration-resistant connections.
- Fast Charging Capability: Up to 100A max charge with low internal resistance for quick recharges (recommended 15-50A), optimized for partial charges and low-temp operation.
- Scalable & Compatible: Single battery use (no series/parallel); pairs seamlessly with Victron, Renogy, and other inverters for high-performance 12V systems.
