12V 100Ah LiFePO4 Battery Group 31 Deep Cycle Lithium Battery for RV Marine

- Customer benefit: 1. You can expect 3,000-5,000 complete charge cycles at 80% depth of discharge before reaching 80% of original capacity. Compared to quality AGM batteries that last only 300-500 cycles, this battery offers a much longer lifespan with minimal maintenance. 2. This battery operates efficiently from -20°F to 140°F (-29°C to 60°C), offering excellent performance in both winter and hot climates. The built-in BMS protects the battery by preventing charging below freezing but allows discharging down to -20°F, ensuring reliable power under any condition. The battery uses stable LiFePO4 chemistry that resists thermal runaway up to 500°F (260°C). It includes advanced BMS protection against overcharge, over-discharge, short circuits, and extreme temperatures, making it ideal for enclosed spaces. 3. While the initial cost may seem higher, this battery pays off quickly through extended lifespan (3,000-5,000 cycles), reduced replacement costs, and increased efficiency. Plus, it saves you money on fuel and maintenance, providing a strong return on investment over time. 4. Maintenance is minimal: store between 20%-80% state of charge when not in use, avoid exposure to direct sunlight, and periodically check terminal connections. No watering or equalization charges required, significantly reducing maintenance compared to lead-acid batteries. 5. Unlike traditional lead-acid batteries, this LiFePO4 battery can be mounted in any orientation—sideways, upside down, or vertically—without risking acid leakage, thanks to its sealed design. This makes installation easier and more flexible. This battery works well with all standard 12V inverters designed for lead-acid batteries. However, for best results, inverters with adjustable low-voltage cutoff settings or dedicated lithium modes are recommended. Many popular brands like Victron and Renogy offer models specifically optimized for LiFePO4 batteries. 6. The battery uses stable LiFePO4 chemistry that resists thermal runaway up to 500°F (260°C). It includes advanced BMS protection against overcharge, over-discharge, short circuits, and extreme temperatures, making it ideal for enclosed spaces. The integrated BMS includes temperature protection that automatically disconnects charging below 32°F (0°C) to prevent cell damage, while still allowing discharging down to -20°F. This ensures optimal performance and safety across a wide range of temperatures. 7. Compatible with MPPT/PWM controllers for solar applications and lithium-ready converters for RVs. For older systems, consider adding a DC-DC charger. Its versatile mounting options and sealed case make it perfect for both solar storage and marine/RV house battery needs. - Why Choose Battery Combinations? 1. Longer Runtime (Parallel Advantage). How it works: Connecting batteries in parallel increases total capacity (Ah), allowing your system to run 30-50% longer between charges. Ideal for: Solar energy storage, electric vehicles (EVs), and off-grid cabins. Customer benefit: Enjoy uninterrupted power for camping, backup energy, or daily commutes. 2. Higher Voltage Output (Series Advantage) How it works: Series connections elevate voltage (V), enabling compatibility with high-demand tools and inverters. Ideal for: Power inverters, industrial machinery, and electric power tools. Customer benefit: Eliminate voltage limitations for heavy-duty applications. 3. Fail-Safe Redundancy How it works: Multiple batteries act as a backup network. If one fails, others keep the system running. Ideal for: Critical systems like medical equipment, security systems, or data centers. Customer benefit: Minimize downtime and protect against power emergencies. 4. Customizable Power Solutions. How it works: Mix series and parallel configurations to tailor voltage/current to your project’s needs. Ideal for: DIY solar setups, RVs, or renewable energy projects.
