CyperOcean 12V 314Ah LiFePO4 Deep Cycle Battery

1. Introduction

This manual provides essential information for the safe and efficient use of your CyperOcean 12V 314Ah LiFePO4 Deep Cycle Battery. Designed for robust performance, this battery is ideal for various applications including RVs, marine vessels, solar power storage, and off-grid systems. Please read this manual thoroughly before installation and operation.

2. Safety Information

⚠ Warning: Please read and adhere to all safety instructions to prevent injury or damage.

• Charging and Storage: Always follow the instruction manual for charging and storage to prevent potential fire risks.
• Disposal: For disposal, consult your local authority's website for information and safely dispose of lithium-ion batteries in accordance with applicable legal requirements.
• Series/Parallel Connection: When connecting batteries in series or parallel, use a multimeter to measure the battery voltage. Ensure that the voltages of all batteries are consistent, or that the voltage difference is less than 0.2V. Connecting batteries beyond this range is prohibited.
• BMS Protection: The integrated 200A Battery Management System (BMS) provides protection against over-voltage, over-current, short-circuit, over-charge, over-discharge, and high/low temperatures.

3. Setup

3.1 Package Contents

Verify that all items are present in the package:

• Battery Unit × 1
• Screws (M8) × 4
• Plastic Insulation Caps × 2
• Technical Manual × 1

3.2 Physical Overview

The battery features a negative terminal (black), a positive terminal (red), and a nylon handle for easy transport.

3.3 Series & Parallel Connection

The CyperOcean 12V 314Ah battery supports system expansion up to 4 batteries in series (4S) and 4 batteries in parallel (4P), allowing for a maximum 4S4P configuration. This enables building energy storage systems up to 48V and 1256Ah (64.3kWh).

Important: Always ensure voltage consistency (difference less than 0.2V) between batteries before connecting in series or parallel. Use appropriate cables and connectors for high current applications.

4. Operating Instructions

4.1 Applications

This deep cycle LiFePO4 battery is versatile and suitable for:

• RV and Marine applications
• Home Energy Storage
• Solar Power Systems (Off-Grid)
• UPS Backup Systems
• Electric Fans and Scooters

4.2 Energy Capacity and Appliance Run Times

With 4019Wh of usable energy, the battery can power various home essentials. Approximate run times for common appliances are:

• 50W Refrigerator: 51 hours
• 1000W Coffee Maker: 2.5 hours
• 800W Microwave: 3 hours
• 500W Washing Machine: 5 hours
• 60W Cooling Fan: 42 hours

4.3 Charging Options

The battery can be charged using several methods:

• LiFePO4 Charger (14.6V/70A): Approximately 4.5 hours for a full charge.
• Solar Panel (≥850W, Sunny Day + 12V MPPT): Approximately 1 sunny day for a full charge.
• Generator (with a 40A DC to DC Charger): Approximately 8 hours for a full charge.

4.4 Low Temperature Protection

The intelligent BMS includes an active Low-Temperature Cutoff feature. This automatically stops charging below 32°F (0°C) to prevent irreversible cell damage, while still allowing safe power discharge down to -4°F (-20°C). The maximum discharge temperature is 158°F (70°C).

5. Maintenance

5.1 Storage Guidelines

• Before long-term storage, charge the battery to approximately 50% capacity and disconnect all load connections.
• Store the battery in a dry, well-ventilated area with temperatures between 0°C (32°F) and 60°C (140°F). Avoid extreme heat or cold.
• If stored for an extended period, recharge the battery to 50% capacity every 3 months to prevent over-discharge.

5.2 Recycling & Disposal

• Dispose of used batteries in compliance with all local environmental regulations.
• Lithium-ion batteries are recyclable. Please send them to designated recycling facilities rather than disposing of them with regular waste.

6. Troubleshooting

While the integrated BMS provides extensive protection, if you encounter issues, consider the following:

• No Power Output: Check all connections for tightness and proper polarity. Verify the battery's state of charge. The BMS may have activated a protection mode (e.g., over-discharge, over-current); disconnect the load and attempt to recharge.
• Charging Issues: Ensure your charger is compatible with LiFePO4 batteries and provides the correct voltage (14.4±0.2V). Check for low-temperature cutoff activation if charging in cold conditions.
• Unusual Behavior: If the battery exhibits unexpected behavior, disconnect it from all loads and charging sources immediately and contact customer support.

7. Specifications

Note: Specifications are subject to change without prior notice.
