COMMON FAULT ANALYSIS

Q: What V level is suitable for use? What V voltage is suitable for this product?

A: This model is suitable for use in the voltage range of 6V to 60V, and the highest expenditure level is 48V, because the 48V battery is fully charged at about 60V, and it will burn out if it is higher. If your battery is higher than 48V, please choose another model.
Q: The relay makes a popping sound after power on!

A: This is because your charging current is too large or the battery capacity is too small, causing the voltage limit to be reached immediately after power on, and the relay is disconnected. After disconnection, the voltage quickly drops to the voltage limit, and charging starts again, and the cycle repeats. At this time, you need to reduce the charging current. Usually the charging current is 1 to 1.5 times the battery capacity. For example, the charging current of a 20AH battery is generally around 2-3A! Note that high current charging will cause battery heating, accelerated aging, bulging, and even explosion!
Q: What is the control method? Can it be automatically cycled? Can it be charged while in use? Can the current be limited?

A: This is voltage control. For example, if you set the voltage lower limit to 12.0V and the voltage upper limit to 14.5V, the power will be cut off when the voltage reaches 14.5V. When the voltage drops to 12.0V, the relay will close again and start charging. You can charge while using it. The voltage control method only plays the role of shutting down and opening, and cannot limit the current. The charging current depends entirely on your charger!
Q: Can a 12V input charge a 24V battery, or can a 48V input charge a 12V battery?

A: This is a simple voltage controller. It only acts as a switch and cannot convert voltage to charge the battery!
