Redefine Starting Power: The Ultimate High-Capacity Lithium Battery

Command every ignition with unwavering certainty. Engineered to outperform and outlast traditional lead-acid batteries, the 12V 56Ah High-Crank LiFePO4 Battery delivers a formidable combination of massive energy storage (716.8Wh) and robust starting power (500 CCA). Designed for the most demanding applications—from large diesel trucks and commercial vehicles to powerful marine outboards and critical backup systems—this battery provides the instant, high-current punch for reliable cold starts paired with deep-cycle resilience for auxiliary needs. Built with premium Grade A LiFePO4 cells and an intelligent Battery Management System (BMS), it offers a maintenance-free, long-lasting power solution backed by Yunfan Factory's 15+ years of lithium expertise.

Engineered Excellence: Superior to Lead-Acid in Every Way

Experience the next generation of starting power with advantages that lead-acid batteries simply cannot match.

1. Unmatched Safety & Stability
Utilizes inherently stable Lithium Iron Phosphate (LiFePO4) chemistry, renowned for superior thermal and chemical stability. It remains secure even under extreme conditions, overcharge, or short circuit, ensuring ultimate safety for high-energy vehicle and marine applications.

2. Rapid Charging & High-Power Discharge
Features exceptional charge current acceptance (up to 50A), enabling swift recharges in hours, not days. Capable of massive continuous discharge current (100A), it effortlessly handles the surge demands of heavy-duty equipment, inverters, and high-performance electrical systems.

3. High Energy Density & Compact Design
Packs a substantial 716.8Wh of energy into a moderately compact and lightweight design (approx. 7.13 kg). This high energy density provides greater power reserves without the bulk, ideal for space-conscious installations in RVs, boats, and vehicles.

4. Ultra-Long Service Life & Eco-Friendly
Boasts an exceptional cycle life of over 4000 cycles—far surpassing the 300-500 cycles of typical lead-acid batteries. With a 10-year design life, it delivers sustainable, economical energy and reduces waste, offering a superior return on investment.

5. Advanced Smart BMS with Connectivity

• Bluetooth Real-Time Monitoring: Check voltage, state of charge, health status, and more directly from your smartphone for unparalleled control and peace of mind.

• Comprehensive Protection: The integrated BMS safeguards against over-charge, over-discharge, over-current, short circuit, and ensures cell balance for optimal performance and durability.

• Self-Heating Function (Optional): Ensures reliable charging and performance even in freezing temperatures as low as -20°C (-4°F).

• Custom App Solutions: Yunfan Factory offers customized Bluetooth APP or neutral APP development for your branding needs.

Frequently Asked Questions (FAQ)

Q1: Is 500 CCA enough for my large diesel truck or boat engine?
A: A 500 CCA rating is robust and suitable for many large diesel and marine applications. We recommend comparing it to your engine manufacturer's (OEM) specified CCA requirement. This LiFePO4 battery delivers its rated power consistently and is engineered to meet or exceed such demanding specifications.

Q2: Can I use my existing lead-acid battery charger with this LiFePO4 battery?
A: No. For optimal performance, safety, and to maximize the battery's lifespan, you must use a charger specifically designed for 12.8V Lithium Iron Phosphate (LiFePO4) chemistry. Using an incompatible lead-acid charger can lead to improper charging and potential damage. Yunfan Factory offers compatible smart chargers as an optional accessory.

Q3: How does the self-heating function work, and do I need it?
A: The optional self-heating function activates in low-temperature environments (typically below 0°C/32°F) to warm the battery cells internally, allowing for safe and efficient charging in cold weather. It is highly recommended for applications in consistently cold climates to ensure year-round reliability.

Q4: What makes this battery "waterproof" and where can it be installed?
A: Our battery is built with a sealed, corrosion-resistant casing designed to withstand harsh, wet environments like marine engine bays. It is suitable for installation in most locations where traditional batteries are placed, though we always recommend avoiding prolonged direct submersion.
