Maintenance Tips

• Keep the battery in a clean, dry environment and avoid prolonged exposure to extreme heat.
• Regularly inspect battery terminals and cables for corrosion, damage, or loose connections.
• Use a compatible LiFePO4 charger and maintain charging voltage within manufacturer specifications.
• Keep the Bluetooth monitoring system active to track battery health, voltage, temperature, and state of charge.
• Store the battery at approximately 50% charge when not in use for extended periods.
• Avoid deep discharges whenever possible to maximize cycle life.
• Ensure ventilation around the battery and keep vents and housing free of dirt and debris.
• Verify the built-in heater is functioning properly before charging in cold-weather conditions.
• Check mounting hardware periodically, especially in RV, marine, and off-grid applications.
• Disconnect power before performing inspections or maintenance.
