This manual provides essential information for the safe and efficient use of your Redodo 12V 300Ah LiFePO4 Battery. Please read it thoroughly before installation and operation.
The Redodo 12V 300Ah LiFePO4 battery offers a high usable capacity, capable of powering common appliances for extended periods. It features automotive-grade cells, ensuring stable performance and greater power output. Weighing approximately one-third of a comparable lead-acid battery, it is designed for portability and ease of installation. This battery provides a significantly longer cycle life, ranging from 4,000 to 15,000 cycles, and an estimated 10-year lifespan, far exceeding traditional lead-acid batteries.
It is ideal for off-grid solar systems and various outdoor applications such as RVs, camping, and marine use. The battery can be connected in series and parallel configurations to achieve higher voltage (up to 48V) and larger capacity (up to 1200Ah).
2. Safety Information
Your Redodo LiFePO4 battery incorporates a built-in 200A Battery Management System (BMS) for comprehensive protection. This BMS safeguards against:
- Overcharge
- Over-discharge
- Overcurrent
- Short circuit
- Over-temperature
The battery utilizes automotive-grade LiFePO4 cells, which are inherently stable and safe. It is 100% safe, non-toxic, and uses renewable energy technology. However, always observe the following general safety precautions:
- Do not disassemble, puncture, or damage the battery.
- Avoid exposing the battery to extreme temperatures, direct sunlight, or fire.
- Use only compatible chargers and charging methods.
- Ensure proper ventilation during charging and discharge.
- Keep terminals free from foreign objects and ensure connections are secure.
- This battery is not suitable for use as a starter battery or in golf carts. It is designed for energy storage applications.
3. Setup and Installation
3.1 What's in the Box
Upon unpacking, verify that all components are present:
- 1 x 12.8V 300Ah Battery
- 1 x Product Manual (this document)
- 2 x Insulation Caps
- 2 x M8 Terminal Bolts
- 2 x Flat Washers
- 1 x Quick Start Guide
3.2 Terminal Specifications and Connections
The battery features M8 terminals. Ensure all connections are tight and secure to prevent arcing and ensure optimal performance.
3.3 Series and Parallel Connections
The Redodo 12V 300Ah LiFePO4 battery supports both series and parallel connections for increased voltage and capacity:
- Parallel Connection: Connect batteries in parallel to increase total capacity while maintaining the same voltage (e.g., two 12V 300Ah batteries in parallel yield 12V 600Ah). Maximum recommended parallel connection is 4 batteries (12V 1200Ah).
- Series Connection: Connect batteries in series to increase total voltage while maintaining the same capacity (e.g., two 12V 300Ah batteries in series yield 24V 300Ah). Maximum recommended series connection is 4 batteries (48V).
- Series-Parallel Connection: Combine series and parallel connections for higher voltage and capacity (e.g., 4P4S configuration can achieve 48V 1200Ah, totaling 61.44 kWh).
Always ensure all batteries in a series or parallel bank are of the same type, capacity, and state of charge before connecting. Consult a qualified professional for complex system designs.
4. Operating Instructions
4.1 Charging Methods
The Redodo 12V 300Ah LiFePO4 battery can be charged using several methods. Always use chargers specifically designed for LiFePO4 batteries with appropriate voltage and current ratings.
- LiFePO4 Battery Charger: A 12V (14.6V) 60A LiFePO4 charger can fully charge the battery in approximately 5 hours.
- Solar Panel with MPPT Controller: A solar panel system with a capacity of 1200W or more, coupled with an MPPT controller (e.g., 40A MPPT), can charge the battery over the course of one day, depending on sunlight conditions.
- Generator (AC-DC Charger): A 60A AC-DC charger connected to a generator can charge the battery in approximately 5 hours.
- Alternator (DC-DC Charger): A 40A DC-DC charger connected to a vehicle's alternator can charge the battery in approximately 7.5 hours.
4.2 Power Output and Appliance Usage
The 12V 300Ah battery provides 3840Wh of usable energy and a maximum continuous power output of 2560W. This capacity allows for extended operation of various appliances:
- Microwave Oven (700W): Approximately 5.48 hours of use.
- Air Fryer (1700W): Approximately 2.25 hours of use.
- Refrigerator (50W): Approximately 76.8 hours of use.
- Coffee Machine (800W): Approximately 4.8 hours of use.
5. Maintenance
LiFePO4 batteries are known for their low maintenance requirements compared to lead-acid batteries. To ensure the longevity and optimal performance of your Redodo battery:
- Regular Inspection: Periodically check the battery terminals for corrosion or loose connections. Clean as necessary.
- Storage: If storing the battery for an extended period, ensure it is charged to approximately 50-70% State of Charge (SOC) and stored in a cool, dry place. Avoid storing in direct sunlight or extreme temperatures.
- Charging: While the BMS protects against over-discharge, it is generally recommended to avoid consistently discharging the battery below 20% SOC to maximize its lifespan.
- Cleaning: Keep the battery casing clean and free of dust and debris. Use a dry cloth for cleaning.
6. Troubleshooting
If you encounter issues with your Redodo LiFePO4 battery, consider the following common troubleshooting steps:
- Battery Not Charging:
- Verify that the charger is correctly connected and functioning.
- Ensure the charger is compatible with LiFePO4 batteries and has the correct voltage output.
- Check for loose or corroded terminal connections.
- Confirm the battery's internal BMS has not activated a protection mode (e.g., due to extreme temperature or over-discharge). Allow the battery to rest or warm up/cool down if necessary.
- Low Power Output:
- Check the battery's State of Charge (SOC). A low SOC will result in reduced power.
- Ensure all connections are secure and cables are of adequate gauge for the current draw.
- Verify that the load does not exceed the battery's maximum continuous discharge current (200A) or maximum load power (2560W).
- Unusual Odor or Heat:
- Immediately disconnect the battery from all loads and chargers.
- Contact Redodo customer support for assistance.
