Check Your Voltage Requirements
Always match the charger voltage (e.g., 54.6V for a 48V pack) to your specific battery. Using the wrong voltage can permanently damage your battery or lead to safety hazards.

E-bike ports vary wildly. Check if your bike uses a 3-pin XLR, RCA, or barrel connector. If you are unsure, choose a kit with multiple interchangeable heads.
Safety Certifications
Always look for UL or ETL certification labels. These indicate that the product has undergone rigorous electrical testing to prevent fires and short circuits.
