Up to four batteries can be connected in series to achieve 48V 35Ah, or up to four batteries can be connected in parallel to achieve 12V 140Ah. Ensure proper polarity and use appropriate cabling for safe and effective connections. The battery terminals are M6 type.
Charging
Proper charging is essential for the battery's performance and lifespan.
Image: This image illustrates two adaptable charging methods for the LiFePO4 battery. The first is Solar Charging, utilizing a solar panel, which is a renewable, cost-effective, and temperature-resistant option. The second is AC Adapter charging, using a standard wall outlet, offering convenience, fast charging, and versatility. Always use LiFePO4 compatible chargers and controllers; never use SLA chargers.
Operating
The ExpertPower LiFePO4 battery can be discharged significantly deeper than traditional lead-acid batteries without incurring damage, allowing for a greater usable capacity.
- Ensure the battery operates within the specified discharge temperature range of -4°F to 140°F (-20°C to 60°C).
- Monitor the battery's voltage and current to stay within safe operating parameters, especially when connecting multiple batteries.
- Avoid exceeding the maximum continuous discharge current specified for the battery to prevent BMS activation and potential shutdown.
Maintenance
Proper maintenance ensures the longevity and optimal performance of your battery.
Storage
For extended storage, follow these guidelines:
Image: A bar graph illustrating the low self-discharge characteristic of the ExpertPower LiFePO4 battery. It shows that the battery retains approximately 98% of its charge after 1 month, 90% after 6 months, and 80% after 1 year. This low self-discharge rate, attributed to the nature of Lithium Iron Phosphate batteries and their high energy density, allows a fully charged battery to potentially hold a charge for up to one year.
- Store the battery in a cool, dry place with temperatures between 32°F to 86°F (0°C to 30°C).
- Due to its low self-discharge rate (approximately 3% per month), a fully charged LiFePO4 battery can maintain a significant charge for up to one year.
- It is recommended to periodically check the battery's state of charge during long-term storage and recharge if necessary to prevent deep discharge.
Troubleshooting
If you encounter issues with your ExpertPower LiFePO4 battery, consider the following:
- Battery Not Charging: Ensure you are using a dedicated LiFePO4 compatible charger. Check all connections for proper contact and polarity. Verify the charger is functioning correctly.
- Battery Shutting Off: The built-in BMS may have activated due to an unsafe condition such as overcharge, deep discharge, overloading, overheating, or low temperature. Allow the battery to return to a safe operating temperature or remove the load.
- Low Voltage Output: Check the battery's state of charge. If multiple batteries are in series or parallel, ensure all connections are secure and that individual batteries are balanced.
- Reduced Performance: Confirm the battery is being used within its specified operating temperature range. Ensure the charging parameters are correct and the battery is fully charged before use.
If problems persist, refer to the warranty and support section for further assistance.
