12V 300Ah LiFePO4 Lithium Battery, Built-in Smart BMS,Low-Temp Protection Up to Group 31 Deep Cycle Battery for Trolling Motor, RV, Solar, Marine, Camping and Off Grid Applications

• 【Automotive-Grade Safety & Stability】 Engineered with automotive-grade LiFePO4 cells for exceptional thermal stability. Non-combustible even under extreme conditions (high temperatures, short circuits, or physical impacts). Exceeds industry safety standards with flame-retardant ABS casing and IP55 waterproof/dustproof protection.
• 【10-Year Lifespan with 4000~7000 Deep Cycles】 Delivers 4000~7000 cycles at 80% depth of discharge (DOD) – 10X longer than lead-acid batteries. Supports 300% DOD without capacity degradation, maximizing usable energy. Ultra-low self-discharge (3%/month) ensures readiness for long-term storage.
• 【Scalable Power for Demanding Systems】 Flexibly configure up to 4S (48V/12.288kWh) or unlimited parallel connections. Flat voltage curve maintains 95% capacity above 12.8V, providing 50% more runtime than lead-acid batteries. Ideal for high-drain applications up to 200A continuous discharge.
• 【Lightweight & All-Weather Performance】 50% lighter than equivalent lead-acid batteries (30.8kg vs. 60kg) for easy installation in RVs, boats, or solar setups. Operates flawlessly from -20°C to 65°C (-4°F to 149°F), outperforming lead-acid in freezing winters or scorching summers.
• 【Smart BMS with Multi-Layer Protection】 Built-in Battery Management System monitors voltage, current, and temperature in real time. Features 7-layer safeguards: overcharge/overdischarge, overcurrent, short-circuit, cell balancing, and dual-temperature cutoff. Maintenance-free design with zero memory effect – charge anytime, anywhere.
