Product Details
Product Description for RELiON RB48V100 48V 100Ah Deep Cycle Lithium Battery RELiON RB48V100 48V 100Ah LiFePO4 Deep Cycle Lithium Battery – High-Capacity Power Solution for Solar, EV, Marine, and Off-Grid Systems Elevate your 48V energy storage with the RELiON RB48V100 48V 100Ah LiFePO4 battery (Model: RB48V100), a robust, high-capacity deep cycle battery designed for demanding solar, electric vehicle (EV), renewable energy, marine, RV, and backup power applications. Delivering 5120Wh of energy with a 200A continuous discharge (250A peak for 4s), this battery provides 100% usable capacity, up to 10x longer life than lead-acid, and fast charging with partial state-of-charge (PSOC) tolerance. 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 IP65-rated steel enclosure. Key Features:
- High-Capacity Performance: 200A continuous and 250A peak discharge, ideal for large solar arrays, EV propulsion, or high-drain devices without derating.
- 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 136.7 lbs with 99% round-trip efficiency and <3% monthly self-discharge for easy handling and minimal maintenance.
- Wide Temperature Resilience: Discharge from -4°F to 131°F (-20°C to 55°C), charge from -4°F to 131°F (-20°C to 55°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 IP65 Steel Enclosure: Dust-tight and water-resistant steel 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 5A-50A), even at low temperatures.
- Scalable & Compatible: Single battery use (max 1 in series); pairs seamlessly with Victron, Renogy, and other inverters for expanded 48V systems.
