Renogy REGO 12V 400Ah Cold Weather LiFePO4 Battery

Product Overview

The Renogy REGO 12V 400Ah Lithium Iron Phosphate Battery is a high-capacity, heavy-duty power storage solution designed for the most demanding off-grid environments. Packing a massive 5.12kWh of energy into a single unit, it is engineered to replace four standard 100Ah batteries, saving over 30% in installation footprint and eliminating cluttered wiring. Featuring an intelligent self-heating function, this battery is specifically built for "cold weather" performance, ensuring safe charging and reliable power delivery even when temperatures drop below freezing.

Key Features

• Ultra-High 5.12kWh Capacity: A single REGO 400Ah battery provides massive storage, capable of powering heavy appliances like air conditioners, refrigerators, and microwaves in vans, yachts, and off-grid cabins.

• Intelligent Self-Heating: Designed for extreme climates, the built-in heater automatically activates when the temperature drops below 41°F (5°C) and a stable 15A+ charge current is detected. This prevents damage and ensures efficient charging in sub-zero conditions.

• Smart BMS & 62 Protections: The next-generation Battery Management System (BMS) offers 62 levels of protection, monitoring everything from cell balance to over-voltage and temperature, ensuring absolute reliability.

• 6,000 Cycle Life: Built with advanced cells that support up to 6,000 cycles at 80% DOD, providing over 10 years of daily use—far outlasting traditional lead-acid or AGM alternatives.

• Rugged & Waterproof: Encased in a vibration-resistant, die-cast aluminum housing with an IP65 waterproof rating, making it ideal for marine, yacht, and outdoor applications.

• Bluetooth Monitoring: Equipped with built-in Bluetooth for real-time monitoring via the Renogy app, alongside CAN (RV-C) communication ports for seamless integration with the REGO all-in-one power system.

• Massive Scalability: Connect up to 8 batteries in parallel to create a massive 40kWh energy bank for large-scale off-grid needs.
