A Start-Stop LiFePO4 Battery is a high-performance, advanced power solution specifically engineered for modern vehicles with automatic start-stop systems. Unlike traditional lead-acid or AGM batteries, it uses Lithium Iron Phosphate (LiFePO4) chemistry, renowned for its safety, stability, and long cycle life.

When your vehicle stops (e.g., at traffic lights), the engine shuts off to save fuel and reduce emissions. The moment you press the accelerator, the battery delivers instant, reliable power to restart the engine smoothly. With a built-in BMS (Battery Management System), it offers protection against overcharging, over-discharging, and extreme temperatures, ensuring maintenance-free operation and enhanced safety.

Key Advantages:

• Long Life: With 5,000+ deep cycles, it lasts 3-5 times longer than traditional AGM/EFB batteries.

• Powerful Performance: Features high CCA (Cold Cranking Amps) for quick starts in all weather conditions.

• Lightweight & Efficient: Up to 50% lighter than lead-acid batteries, improving fuel efficiency.

• Eco-Friendly: No heavy metals, fully recyclable, and reduces carbon emissions.

Our LiFePO4 batteries are versatile and reliable for a wide range of vehicles and machinery:

• Passenger Vehicles: Ideal for cars, SUVs, and crossovers with start-stop systems, ensuring fuel savings and uninterrupted power for daily commutes.

• Commercial Fleets: Perfect for trucks, vans, and delivery vehicles that undergo frequent stops, reducing downtime and operational costs.

• Marine & RVs: Provides dual-purpose cranking and deep-cycle power for boats, yachts, and recreational vehicles, supporting both engine starts and onboard electronics.

• Off-Road & Specialty Vehicles: Designed to handle high vibrations and extreme conditions in construction machinery, agricultural equipment, and emergency vehicles

Q1: Is this a direct replacement for my car’s original AGM/EFB battery?
A: Yes! Most models are drop-in replacements for AGM/EFB batteries. Confirm your vehicle’s group size, or contact us for compatibility.

Q2: Why choose LiFePO4 over traditional AGM?
A: LiFePO4 offers longer lifespan (3,000+ cycles), higher CCA, lighter weight, and maintenance-free operation—making it more cost-effective over time.

Q3: Is it safe?
A: Absolutely. LiFePO4 chemistry is inherently stable and non-combustible. Coupled with a smart BMS, it prevents overcharge, short circuits, and thermal issues.

Q4: What’s your MOQ and warranty?
A: We offer flexible MOQs for OEM/ODM partners. Warranty typically ranges from 3 to 5 years, depending on the product.

Q5: Can I use it in extreme temperatures?
A: Yes! Our batteries operate reliably in a wide temperature range (-20°C to 60°C), perfect for harsh climates
