12V 300Ah Deep Cycle Lithium Iron Phosphate Battery w/ Self-Heating |

Product Overview

The Renogy 12V 300Ah Core Series LiFePO4 Battery is a high-capacity powerhouse designed for all-weather off-grid living. Engineered to provide 59% more power than a standard 200Ah battery within a similar footprint, it is the ultimate upgrade for full-time nomads, remote cabin owners, and marine enthusiasts. Featuring industry-leading 200W heating elements, this battery solves the biggest challenge of lithium power: charging in the cold. Whether you’re facing a winter storm in your RV or powering a secluded retreat, the Core 300Ah ensures you have the energy density to stay comfortable for days.

Key Features

Massive Energy Density: Delivering a substantial 3.84kWh of energy, a single Core 300Ah battery provides nearly 10 times the lifespan of a typical lead-acid battery. It uses EV-grade cells for consistent, long-lasting performance.
2X Faster Self-Heating: Equipped with the industry’s highest-rated 200W heating elements, this battery thaws itself twice as fast as competitors. The self-heating function activates automatically at 32°F (0°C) when a charging current of 10A or greater is detected, ensuring safe charging in frigid environments.
Smart BMS Protection: The integrated 200A Battery Management System (BMS) offers a full suite of protections, including a low-temperature cut-off, over-charge, over-discharge, and short-circuit protection.
Rugged, Impact-Resistant Design: Built for the "bumpy journey," the battery features a reinforced internal structure and a rugged shell to protect sensitive components from the vibrations of off-road travel or heavy waves.
Scalable Power Solutions: Build a massive energy bank to suit your needs. Support for up to 16 batteries in a 4P4S configuration allows you to create a 48V system with a staggering 61.44kWh of total storage.
Maintenance-Free & Durable: Rated for 5,000 cycles at 80% Depth of Discharge (DOD), providing over a decade of reliable service with zero maintenance required.
