Package List: 5 x High Voltage Generator Note: 1. The high voltage module should be avoided to be powered on when the high voltage is no load. Before power on, the appropriate distance from the high voltage line must be adjusted. The arcing distance of the high voltage line is proportional to the voltage and capacity of the battery used.2. When testing the arc distance, the experiment should be from short to long. It is strictly forbidden to exceed the longest arcing distance when power is on. Because the high voltage energy cannot be released, it is very easy to damage the module.3. The power of the module is large, and it is not suitable for heat dissipation inside, so it cannot work for a long time.4. The way to judge whether the battery capacity can drive the maximum output power is to measure the battery voltage when the arc is drawn. If it is around 6V, it can output the maximum power.5. Two small capacity lithium batteries are connected in series to 7.2V, and the measured voltage has dropped to about 4V in the arcing state. The smaller the capacity, the lower the voltage. Therefore, it is recommended to use a lithium battery of more than 2000MA, and it is best to use a battery of more than 4000MA if possible.
