Features
Details from the ECO-WORTHY L13L400AH-1 Amazon listing:
- Metal Case for Safer Installation: The ECO-WORTHY 12V 400Ah LiFePO4 Battery features a reinforced metal enclosure for better heat resistance, fire protection, and durability than standard plastic cases. With built-in mounting feet, it can be securely installed directly in RVs, campers, or off-grid systems without an extra battery box, saving space while keeping your setup clean and stable
- Dedicated Safety Switch: Equipped with an independent weak-current power switch, allowing users to safely disconnect battery output with one touch during installation, wiring, maintenance, or long-term storage. Compared with directly disconnecting high-current terminals, it helps reduce spark risks during operation. The switch also helps minimize standby power consumption during extended storage periods, reducing battery self-discharge and helping preserve battery capacity over time
- Engineered to Handle Road Vibration & Harsh Terrain: The rugged steel shell combined with reinforced internal cell fixing brackets helps minimize movement and vibration during travel. Whether driving on highways, mountain roads, or off-road terrain, the battery remains stable and protected, making it ideal for RV, van life, trailer, and mobile power applications
- Smart Bluetooth Monitoring & Low-Temperature Protection: Stay connected to your battery performance anytime through the Bluetooth app, allowing real-time monitoring of voltage, battery level, charging/discharging status, and system health. The integrated smart BMS also features low-temperature charging protection, automatically stopping charging in freezing conditions to help extend battery lifespan
- Premium Grade A Cells with Advanced 250A BMS Protection: The ECO-WORTHY 12V 400Ah Battery uses high-quality Grade A LiFePO4 cells paired with a robust 250A Battery Management System for reliable long-term performance. The BMS provides protection against overcharge, over-discharge, over-current, overheating, and short circuits, ensuring safe and stable power delivery for high-capacity energy systems
