12V 200Ah Self-Heating LiFePO4 Battery for Cold-Weather Energy Storage
This is a 12-volt lithium iron phosphate (LiFePO4) battery designed for large-capacity energy storage in cold-weather environments. It is suited for RVs, home backup systems, off-grid installations, and other applications where reliable winter charging and high continuous output are required. The integrated self-heating system supports charging in freezing conditions, while the high-current BMS allows the battery to supply sustained power to larger loads and inverters.
Important: Do not use this battery as a starter or engine-cranking battery. Do not orient the battery with the top or front side facing downward; other orientations are acceptable. The self-heating system activates below 41°F and stops at 50°F or higher.
Key Features
- Integrated self-heating system: Uses 150W heating pads to warm the cells for safe charging in cold conditions, reducing winter downtime.
- Cold-weather charging support: Heats from approximately 14°F in 70–90 minutes and from −4°F in 100–150 minutes to reach charging-ready temperatures.
- 200A battery management system: Supports up to 200A continuous charge and discharge for higher-power inverters and demanding DC loads.
- High-capacity energy storage: Provides 2560Wh of usable energy and up to 2560W of continuous output power.
- EV-grade LiFePO4 cells: Built with lithium iron phosphate cells rated for long cycle life across a wide range of depth-of-discharge levels.
- Comprehensive protection features: Includes over 20 protections such as overload protection with automatic recovery, moisture resistance, salt-spray resistance, and a pre-charge function.
- Flexible charging sources: Supports charging from a battery charger, solar system, alternator, or generator.
