10. User Tips
- Choosing a Replacement Battery: When selecting a replacement battery, always ensure the new battery pack's size is suitable for your ebike's compartment. The battery voltage must be the same as your original battery (e.g., 48V for 48V systems) unless you are certain your motor has a wider working voltage range. If the battery box size allows, you can choose a higher capacity (e.g., 12Ah or 14Ah instead of 10.4Ah) for extended range.
- Understanding BMS: The Battery Management System (BMS) is a crucial circuit board that protects your battery pack, ensuring safe operation by managing charging, discharging, and temperature.
