Maintenance Tips

• Use a Lithium-Compatible Charger – Always charge the LiFePO4 battery using a LiFePO4-specific charger to ensure proper voltage regulation and prevent overcharging, which can damage the battery and shorten its lifespan.

• Keep Charge Between 20% and 100% – To extend the battery’s life, maintain a charge level between 20% and 100%. Avoid discharging the battery below 10V, as deep discharges can lead to permanent damage.

• Ideal Operating Temperature – LiFePO4 batteries work best in a temperature range of -4°F to 140°F. Charging the battery in temperatures below 32°F can cause damage, so ensure the battery is at an appropriate temperature before charging.

• Secure Installation – Ensure the battery is properly mounted and securely fixed in place to prevent vibrations that can damage internal components and reduce the battery's performance over time.

• Inspect and Clean Terminals – Regularly inspect the battery terminals for any corrosion or loose connections. Apply dielectric grease to protect against oxidation and ensure good conductivity.

• Proper Storage – If you need to store the battery for extended periods, keep it at 50-80% charge and store it in a cool, dry place. Disconnect the battery from the vehicle to avoid parasitic drain.

• Avoid Jump-Starting with Lead-Acid Batteries – Do not jump-start using a traditional lead-acid battery, as this can generate harmful voltage spikes that may damage the Battery Management System (BMS). Use jump-starting equipment specifically designed for LiFePO4 batteries.

• Monitor the BMS – The Battery Management System (BMS) protects the battery from overcharging, deep discharges, and overheating. If the BMS shuts down the battery, wait for it to reset before recharging.

• Limit Deep Discharges – LiFePO4 batteries are more resilient to deep discharges than lead-acid batteries, but to ensure long-term health, avoid regularly discharging the battery below 20%.

• Follow Manufacturer’s Guidelines – Always follow the manufacturer’s maintenance and usage recommendations to ensure your LiFePO4 battery performs optimally and lasts as long as possible.
