How Your 6.4V LiFe Battery Backup Power Pack Works
Discover how this battery backup keeps your small pump or water feature running reliably, with optimized solar charging and smart power management—including timer and adjustable output.
System Overview
1. Simple Solar Charging
Connect a 6–10V solar panel (6–10W, not included) using the battery pack's 5m cable with standard DC plug.
Panel charges the battery automatically, whether the system is ON or OFF.
2. One Output Connection
Connect a single 6–9V DC pond pump or device (up to 5W) to the standard DC output socket on the battery box.
Check your device’s connector and voltage for compatibility before use.
3. Adjustable Power (Potentiometer)
Use the built-in potentiometer to reduce power output and run your pump more efficiently.
Turning down the power lowers voltage, saves energy, and can extend battery runtime.
4. Intelligent Timer Mode
Activate Timer mode to run your device for 10 minutes every hour (if battery charge allows).
If battery charge is too low, the system automatically skips a cycle and tries again later.
Timer ON light shows when this feature is active.
5. Easy Operation & Indicators
System ON/OFF button for all-power control.
Status lights show System ON and Timer ON at a glance.
6. Battery Safeguards
Automatic shutoff protects against deep discharge, extending battery lifespan.
System remains off until battery is recharged to a safe level.
Best Practices for Effective Operation
Use a solar panel within the recommended 6–10V, 6–10W range for best results.
Keep your panel in full sun and clean to ensure reliable charging.
Set your pump to a lower power level for longer run times, especially in cloudy weather.
Timer mode is ideal for saving power when sunlight is limited.
