1. Safety & Smart Features
Q: I plugged the charger into the wall, but there is no voltage at the connector. Is it broken?
A: Not at all! This is our Zero-Voltage Standby safety feature. The charger will not output voltage until it intelligently detects a secure connection to your battery. This prevents dangerous sparks and protects your battery terminals from electrical arcing.
Q: What happens if I accidentally connect the positive and negative wires backward?
A: No need to worry. The charger is equipped with Automatic Polarity Identification. It will recognize the error and refuse to start, keeping both you and your battery 100% safe.
Q: What does it mean when the Blue LED stays on (Solid Blue)?
A: This is the Fault Self-Diagnosis mode. The charger has detected an anomaly—such as a mismatch in the charging curve or potential battery overheating (Thermal Runaway). It has locked the system for your safety. Please check your battery health or contact technical support.
2. Performance & Maintenance
Q: What is "Pulse Repair" and how does it help my battery?
A: Over time, LiFePO4 cells can develop minor inconsistencies. When the charger reaches 100%, it enters Breathing Mode (Blue light pulses). It provides a controlled pulse for 20 minutes to balance cells and "clean" the internal chemistry, extending your battery's life and range.
Q: Does this charger support different battery types?
A: This specific series is optimized for LiFePO4 (Lithium Iron Phosphate) batteries. We offer specialized versions for 60V (20S) and 72V (24S) configurations. Please ensure your charger voltage matches your battery pack specifications.
Q: Why is this charger better than a standard "Fast Charger"?
A: Standard fast chargers can cause heat buildup and "surface charging" (where the battery looks full but isn't). Our Multi-Stage Saturation ensures the battery is deeply charged to 100% capacity, giving you more miles per charge.
3. Durability & Quality
Q: Is the charger casing durable for industrial use?
A: Yes. We use a thickened ABS+PC flame-retardant material. It is designed to be heat-resistant and impact-resistant, making it suitable for professional delivery fleets and rugged environments.
Q: Is the power cord safe for long-term use?
A: Absolutely. We use high-quality, 3C-certified extended power cords. They are thicker than standard cables to prevent overheating during high-current charging sessions.
4. Purchasing & Factory Support
Q: Can I customize the connector or the brand label?
A: Yes! As a Source Factory (Xuzhou Yunzhichuan New Energy Co., Ltd), we provide full OEM/ODM services. We can customize output connectors (Anderson, Aviation, T-plug, etc.) and add your company branding for bulk orders.
Q: Do you provide a warranty?
A: We offer a professional factory warranty. Because we can diagnose many issues via the Bluetooth App data on our matching batteries, we provide fast and accurate technical support.
