A dead Lipo battery can be frustrating, especially for Autel X-Star Premium drone users. Sometimes, due to infrequent use or improper storage, your Autel X-star Premium Battery White might refuse to charge. Before you rush to replace it, there’s a potential solution to revive it. This guide outlines a method to potentially recover a Lipo battery that has dropped below the acceptable voltage threshold.
Reviving a Lipo Battery: A Step-by-Step Guide
A Lipo cell that falls below 3 volts has likely suffered significant damage. Most chargers will refuse to recognize or charge such a battery. However, following this careful procedure may help revive it:
Initial Setup:
- NIMH Mode: Set your charger to NIMH mode. This is crucial for the initial charging stage.
- Bypass Balancing Connector: Connect your Autel X-Star Premium battery white to the charger without using the balancing connector. Use the appropriate cell count selection on your charger that closest matches your battery’s configuration.
- Lipo Tester: Connect a Lipo tester to the balancing port of your battery. This allows you to monitor the individual cell voltages throughout the process.
- Low Current Charging: If possible, set the charging current to 250 or 300mA. If your charger doesn’t allow such low current, use the lowest possible setting.
Monitoring and Recovery:
- Close Monitoring: Continuously monitor the voltage readings on the Lipo tester. Pay close attention to the voltage of the cell that dropped below 3 volts.
- 3.0 Volt Threshold: Once the voltage of the weakened cell reaches 3.0 volts, immediately stop the charging process in NIMH mode. This is a critical step to prevent potential damage.
Final Charging:
- Lipo Mode: Switch your charger back to Lipo mode.
- Normal Charging: Now, connect the balancing connector and charge your Autel X-Star Premium battery white normally. The charger should now recognize and charge the battery correctly.
This technique can also be effective for reviving a Lipo battery with one or more weakening cells, even if they haven’t dropped below the 3-volt mark.
This revival method isn’t a guaranteed fix, but it’s often successful in bringing seemingly dead Lipo batteries back to life. Remember, battery safety is paramount. If you notice any unusual swelling, heat, or odor during the process, immediately disconnect the battery and charger. If the battery remains unresponsive after attempting this procedure, it might be time for a replacement. Always prioritize safety when working with Lipo batteries.
