Maintenance Tips
-
Use a Lithium-Compatible Charger – Always use a LiFePO4-specific charger to charge your battery. Lead-acid chargers are not suitable and can cause overcharging, potentially damaging the battery.
-
Maintain Charge Between 20% and 100% – To extend battery life, keep the charge between 20% and 100%. Avoid letting the charge drop below 10V, as this can cause irreversible damage to the battery.
-
Temperature Considerations – LiFePO4 batteries perform best in temperatures ranging from -4°F to 140°F. Always avoid charging the battery when it is too cold (below 32°F) to prevent performance issues.
-
Secure Battery Installation – Ensure that the battery is properly mounted to avoid unnecessary vibrations that can damage the internal components over time.
-
Regularly Check and Clean Terminals – Inspect the terminals for any corrosion or looseness. Apply dielectric grease to prevent corrosion and ensure a secure connection for optimal performance.
-
Storage Recommendations – If storing the battery, keep it at 50-80% charge and store it in a cool, dry place. Disconnect the battery from the vehicle to prevent any parasitic drain.
-
Avoid Jump-Starting with Lead-Acid Batteries – Never jump-start the battery using a traditional lead-acid battery, as this can create harmful voltage spikes that could damage the Battery Management System (BMS).
-
Monitor Battery Management System (BMS) – The BMS prevents overcharging, deep discharges, and overheating. If the BMS activates and shuts down the battery, allow it to reset before trying to charge again.
-
Limit Deep Discharges – While LiFePO4 batteries are more tolerant of deep discharges compared to traditional lead-acid batteries, try to avoid regular discharges below 20% for better longevity.
-
Follow Manufacturer Instructions – Always follow the manufacturer’s guidelines for optimal care, including charging and maintenance practices, to ensure the LiFePO4 battery provides maximum performance and longevity.
