Product Details
RELiON RB20-LT 12V 20Ah Cold Weather LiFePO4 Deep Cycle Battery
RELiON RB20-LT 12V 20Ah Cold Weather LiFePO4 Deep Cycle Battery (Model: RB20-LT) – High-Performance Power Solution for Marine, RV, Solar, Industrial, and Recreational Applications in Cold Climates
The RELiON RB20-LT 12V 20Ah Cold Weather LiFePO4 Deep Cycle Battery (Part No: RB20-LT) is a lightweight powerhouse optimized for low-temperature performance, delivering 20Ah of reliable LiFePO4 power at 12.8V (256Wh), offering twice the usable capacity of lead-acid batteries at half the weight (just 6.6 lbs), with over 3,500 cycles at 80% DoD. Featuring an integrated BMS for safety and efficiency, self-heating technology for safe charging down to -4°F (-20°C), IP66 waterproof enclosure for harsh environments, and F2 terminals for easy integration, it supports 20A continuous discharge (40A peak for 7.5s), making it ideal for small solar energy systems, remote monitoring, LED lighting, traffic control cameras, or as a direct replacement for UB12200 SLA batteries in maintenance-free applications requiring cold-weather reliability.
Key Features:
- Cold Weather Ready: Self-heating system draws power from the charger for safe charging down to -4°F (-20°C), with a heating rate of approximately 36°F/hr.
- High-Capacity Design: 20Ah at 12.8V (256Wh) for reliable performance in 12V systems, perfect for lighter industrial and recreational loads.
- Integrated BMS: Protects against overcharge, over-discharge, short-circuit, and thermal issues; ensures cell balancing for optimal longevity.
- High Discharge Capability: 20A continuous / 40A peak (7.5s) for powering devices up to 256W or high-draw electronics.
- Extended Cycle Life: 3,500+ cycles at 80% DoD, with <3% monthly self-discharge for reliable standby power.
- Versatile Compatibility: Drop-in replacement for UB12200 SLA batteries; supports series/parallel configurations (up to 3S); compatible with most 12V chargers.
- Rugged Durability: IP66-rated ABS enclosure, vibration-resistant for marine and outdoor use; operates from -4°F to 140°F discharge.
- Eco-Friendly: Non-toxic LiFePO4 chemistry, recyclable, and zero maintenance compared to lead-acid alternatives.
- 10-Year Warranty: Backed by RELiON’s commitment to quality in engineered applications.
