RELiON RB300-LT 12V 300Ah LiFePO4 Cold Weather Deep Cycle Lithium Battery – Extreme Low-Temperature Power Solution for Marine, Solar, RV, and Off-Grid Systems
Conquer harsh winters with the RELiON RB300-LT 12V 300Ah LiFePO4 battery (Model: RB300-LT), a lightweight, Group 8D-sized deep cycle battery from the LT (Low Temperature) Series. Delivering 3840Wh of energy with a 100A continuous discharge (200A peak for 7.5s), this battery features an integrated heating system that draws power from the charger for safe charging down to -4°F (-20°C), making it ideal for cold-weather marine operations, off-grid solar in extreme climates, RV adventures, and remote backup power. Its advanced Battery Management System (BMS) protects against overcharge, over-discharge, short circuits, and thermal extremes, ensuring reliable performance in rugged environments with an IP67 waterproof enclosure. Key Features:
- Cold Weather Ready: Built-in heating element activates using charger power at -4°F to 41°F (-20°C to 5°C), enabling safe charging in sub-zero temps with reduced rates below 32°F—no extra components needed.
- High-Capacity Performance: 100A continuous and 200A peak discharge, delivering 100% usable capacity for trolling motors, solar arrays, 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 long-term durability.
- Lightweight & Efficient: Only 76.1 lbs with 99% round-trip efficiency and <3% monthly self-discharge for easy installation and low 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).
- Safe & Certified: UN38.3, UKCA, CE (battery), UL1642 (cells), IEC62133 (cells), and UN 3480 compliant; non-toxic LiFePO4 chemistry with no gassing or fumes.
- Rugged IP67 Enclosure: Fully waterproof and dust-tight ABS & Polycarbonate blend (UL94-V0) case with M8 threaded terminals for secure, vibration-proof connections.
- Scalable & Compatible: Parallel configuration supported; pairs with Victron, Renogy, and other inverters for expanded systems (max 1 in series).
