Maximizing the performance and lifespan of your Hailong battery packs requires correct usage, proper handling, and regular maintenance. Hailong packs are engineered for reliability and long cycle life, but following best practices ensures maximum safety and return on investment—especially for B2B partners managing fleets or reselling batteries.
Use the Correct Charger: Always use a charger matched to your battery’s voltage and BMS requirements.
Avoid Deep Discharge: Charge the battery before it’s fully empty to extend cycle life.
Store in Moderate Temperatures: Keep batteries between 0°C and 35°C when storing for long periods.
Keep Dry and Clean: Avoid exposure to moisture and clean contacts regularly.
Check for Physical Damage: Inspect the case and wiring before each use. Do not use batteries with visible damage.
Charge After Use: If the battery won’t be used for a week or more, store at 50–70% charge to prevent capacity loss.
Balance Charge Regularly: For best results, use a charger with balance mode, especially after frequent deep cycles.
Monitor Performance: Track battery run-time and charging times; any sudden drops may indicate the need for service.
Follow Manufacturer’s Recommendations: Refer to provided manuals and technical sheets for your specific model.
Adhering to these guidelines helps ensure Hailong battery packs deliver long-lasting, safe, and dependable power—supporting smooth operation for your customers and business.
Selecting the right Hailong battery pack is critical for ensuring your eBike products deliver reliable performance and meet market expectations. This guide helps B2B buyers—from OEMs to fleet operators—make the optimal choice.
Identify eBike Model Compatibility: Confirm that your frame supports Hailong case mounting. Most mountain, commuter, and city e-bikes with down-tube battery designs are compatible.
Choose Voltage & Capacity: Decide on 36V, 48V, or 52V according to your motor specifications and performance goals. Pick capacity (e.g., 10Ah, 14Ah, 17.5Ah) based on desired range.
Select Quality Cells: Opt for trusted brands (Samsung, LG, etc.) to ensure long cycle life and stable output. Ask your supplier for cell options.
Consider BMS Functions: Look for features like short-circuit, overcharge, over-discharge protection, and Bluetooth/app diagnostics if needed for your market.
Connector & Mounting: Make sure the battery connector matches your controller (XT60, Anderson, etc.). Double-check mounting brackets and locks for ease of installation.
Check Certifications: For export, especially to the EU/US, ensure the battery comes with UN38.3, CE, MSDS, and other relevant certifications.
Customize Branding: Leverage custom casing colors, logos, or packaging for private label/OEM business.
Evaluate Lead Time & MOQ: Confirm production lead times and minimum order quantity align with your business needs.
Ask for Warranty & Support: Reliable after-sales support and clear warranty terms help minimize your business risks.
Sample Testing: Before bulk order, test a sample in your specific eBike model to verify fit and electrical compatibility.
By following these steps, you can confidently select a Hailong battery pack that matches your eBike business requirements—ensuring performance, safety, and smooth customer experience.
