CyperOcean 12V 314Ah LiFePO4 Battery User Manual

1. Safety Information

Disclaimer: ⚠️⚠️Please mind potential fire risk and strictly follow the instruction manual for charging and storage. For disposal, please check your local authority's website for more information and dispose of the lithium-ion battery safely in accordance with the applicable legal requirements.

Important Warning for Connections: When connecting batteries in series or parallel, use a multimeter to measure the battery voltage. It must be ensured that the voltages of all batteries are consistent, or the voltage difference is less than 0.2V. Connecting batteries beyond this range is prohibited.

3. Technical Specifications

4. Setup and Connection

Series & Parallel Battery Connection

The CyperOcean 12V 314Ah LiFePO4 battery supports both series and parallel connections to achieve higher voltage or capacity. The maximum configuration is 4 Series (4S) and 4 Parallel (4P).

Series Connection

Connecting batteries in series increases the total voltage while keeping the capacity the same. For example, four 12.8V batteries connected in series will result in a 51.2V system with the same capacity as a single battery (e.g., 314Ah).

Parallel Connection

Connecting batteries in parallel increases the total capacity while keeping the voltage the same. For example, four 12.8V 314Ah batteries connected in parallel will result in a 12.8V system with a total capacity of 1256Ah (4 x 314Ah).

Maximum Connection (4S4P)

A 4S4P configuration means connecting four batteries in series, and then connecting four such series strings in parallel. This allows for a maximum system of 51.2V and 1256Ah, providing a massive 63.48kWh of energy storage.

Important: Always ensure all batteries have consistent voltage (within 0.2V) before connecting them in series or parallel. Use appropriate cables and connectors for safe and efficient operation.

5. Operating Guidelines

Discharging and Protection

The battery is equipped with an advanced 200A Battery Management System (BMS) that provides comprehensive protection:

• Over-Voltage Protection
• Over-Charge Protection
• Over-Current Protection
• Over-Discharge Protection
• Short-Circuit Protection
• High/Low-Temperature Protection

6. Maintenance (Storage Guidelines)

• Charge the battery to 50% capacity before long-term storage.
• Disconnect all load connections when storing the battery.
• Store the battery in a dry, well-ventilated area with temperatures between 0°C and 60°C (32°F and 140°F). Avoid extreme heat or cold.
• If stored long-term, recharge the battery to 50% capacity every 3 months to prevent over-discharge and maintain battery health.

7. User Tips

• Always use a compatible LiFePO4 charger to ensure optimal charging and battery longevity.
• When building a battery bank (series or parallel), ensure all batteries are from the same manufacturer, model, and have similar charge states for best performance and safety.
• Provide adequate ventilation around the battery, especially during charging and heavy discharge, to prevent heat buildup.
• Regularly inspect battery terminals for corrosion and ensure connections are tight.

8. Warranty Coverage

The CyperOcean 12V 314Ah LiFePO4 Battery comes with a 5-year limited warranty from the date of purchase.

What is Not Covered by Warranty:

• Improper installation, use, maintenance, or storage.
• Reverse polarity, short circuit, overcharging, or undercharging.
• External damage (impact, collision, drop) or unauthorized modification.
• Exceeding the maximum series-parallel configuration (4S4P) or using with third-party products.
• Commercial use with 80%+ discharge depth within 24 hours, or long-term inactivity (over 1 year without charging).
• Damage caused by force majeure (fire, flood, earthquake, etc.).

9. Recycling & Disposal

Lithium-ion batteries must be disposed of responsibly. Please follow these guidelines:

• Dispose of used batteries in compliance with all local environmental regulations and laws.
• Lithium-ion batteries are recyclable. Do not dispose of them in regular household waste.
• Send used batteries to designated recycling facilities or collection points that handle lithium-ion batteries. Consult your local authority's website for more information on safe disposal options in your area.
