Maintenance Tips

• Use a Lithium-Compatible Charger – Always use a LiFePO4-specific charger for charging. Traditional lead-acid chargers may overcharge or damage the battery, reducing its lifespan and performance.

• Keep Charge Between 20% and 100% – For optimal health, maintain the charge between 20% and 100%. Avoid letting the charge drop below 10V, as deep discharges can permanently degrade the battery.

• Temperature Considerations – LiFePO4 batteries perform best at temperatures between -4°F and 140°F. Avoid charging below 32°F, as cold temperatures can affect battery performance and longevity.

• Secure Battery Installation – Ensure the battery is securely fastened to avoid vibrations that could damage internal components over time, ensuring stable performance.

• Regular Terminal Inspection – Check the battery terminals periodically for corrosion or looseness. Use dielectric grease to prevent oxidation and ensure a secure, reliable connection.

• Storage Best Practices – If storing the battery for extended periods, maintain it at 50-80% charge and store it in a cool, dry environment. Disconnect the battery from the vehicle to prevent parasitic drain.

• Avoid Jump-Starting with Lead-Acid Batteries – Never use a lead-acid battery to jump-start your LiFePO4 battery, as this can create damaging voltage spikes that can harm the Battery Management System (BMS). Use only compatible jump-starting equipment.

• Monitor the BMS – The Battery Management System (BMS) protects against overcharging, deep discharges, and overheating. If the BMS shuts down the battery, allow it to reset before attempting to recharge.

• Limit Deep Discharges – Although LiFePO4 batteries are resilient to deep discharges, consistently discharging below 20% can reduce their lifespan. It's best to keep the charge within the recommended range.

• Follow Manufacturer Guidelines – Always adhere to the manufacturer’s instructions and care guidelines to ensure your LiFePO4 battery performs at its best and lasts as long as possible.
