3. Product Features

• Automotive Grade A Lithium Cells: Constructed with high-quality Grade A lithium-ion cells for superior energy density, stability, and power output.
• Lightweight and Compact: Weighs only 37 lbs and measures 18.9 x 17.4 x 5.2 inches, offering a 30% weight reduction and 50% volume reduction compared to lead-acid batteries of similar energy.
• 48V High Voltage & Large Capacity: Provides 2560Wh usable energy and supports up to 2560W load power. Supports parallel connection (up to 8 units) for building large capacity home energy systems (Max. 48V 400Ah, 20.48kW load power).
• Long Lifespan: Offers 4,000 to 15,000 cycles (4,000 cycles at 100% DOD, 6,000 cycles at 80% DOD, 15,000 cycles at 60% DOD), resulting in a lifespan of up to 10 years.
• Smart BMS Protection: Integrated Battery Management System protects against over-voltage, overcharging, over-discharging, short circuits, over-current, and high/low temperatures. Includes a built-in high-temp cut-off at 122 °F (50 °C).
• Environmentally Friendly: Stable and safe, with no risk of explosion or burning. Does not contain heavy metals, making it more environmentally friendly than lead-acid batteries.

5. Setup and Installation

The CYCCLEVOLT 48V 50Ah LiFePO4 battery is designed for easy installation, eliminating the need for complex wiring often associated with multiple 12V batteries in series. It supports parallel connection for increased capacity.

• Parallel Connection: The battery supports wiring in parallel. It is suggested not to connect more than 8 units in parallel to build a large capacity 48V system. Series connection is not supported.
• Simplified Wiring: With a single 48V unit, you avoid tangled cables and the need to balance voltage, simplifying installation and saving space.
• Terminal Type: The battery uses M8 Terminal-16mm for secure connections.

6. Operating Instructions

The battery is designed for efficient and safe operation across various applications.

• Charging: Supports fast charging and solar panel charging. Can be fully charged in approximately 5 hours with a 10A fast charger.
• Temperature Considerations: The built-in BMS includes low-temp cut-off protection for discharging below 4°F (-20°C) and charging below 32°F (0°C), ensuring safe operation in diverse climates.
• Power Output: Provides 2560Wh of usable energy and supports a maximum load power of 2560W, suitable for powering various appliances and devices.

7. Maintenance

Proper maintenance ensures the longevity and optimal performance of your LiFePO4 battery.

• Regular Inspection: Periodically check battery terminals for cleanliness and tightness. Ensure all connections are secure.
• Storage: For long-term storage, charge the battery to approximately 50% State of Charge (SOC) and store it in a cool, dry place away from direct sunlight and extreme temperatures.
• Avoid Deep Discharge: While LiFePO4 batteries tolerate deep discharge well, avoiding consistent full discharge cycles can further extend their lifespan.

8. Troubleshooting

If you encounter issues with your CYCCLEVOLT battery, consider the following common troubleshooting steps:

• Battery Not Charging: Check charger connections, ensure the charger is compatible with LiFePO4 batteries, and verify the power source. The BMS may have activated a protection mode (e.g., low-temp cut-off).
• No Power Output: Verify that the battery is sufficiently charged. Check all connections to the load. The BMS may have activated a protection mode (e.g., over-discharge, over-current, short-circuit).
• Unusual Odor or Heat: Immediately disconnect the battery from all loads and chargers. Contact customer support.
• BMS Activation: If the battery is completely discharged, it may require activation by connecting it to a compatible charger for a few minutes. Refer to the 'How to activate BMS' video in the Setup section.

9. Common Applications

The CYCCLEVOLT 48V 50Ah LiFePO4 battery is versatile and suitable for a wide range of applications:

• RVs and Camping: Provides reliable power for appliances and electronics during recreational travel and outdoor adventures.
• Trolling Motors: Offers consistent and long-lasting power for marine applications.
