Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please in kind prevail. 4. Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering. Common sense for battery voltage Different battery materials, new/old condition of battery, and different controller data make battery voltage reflects differently. Please check your battery voltage data according to your battery. The maximum voltage indicates full charge. The low voltage indicates that the battery is exhausted. 12V ebike max voltage 12V, min voltage 9V 24V ebike max voltage 29 V, min voltage 21V 36V ebike max voltage 42V, min voltage 29V 48V ebike max voltage 54V, min voltage 39V 60V ebike max voltage 72V, min voltage 49V 72V ebike max voltage 84V, min voltage 60V Package List：
