The high-voltage module should avoid being energized when the high-voltage is no-load. Before powering on, the appropriate distance of the high-voltage line end must be adjusted. The arcing distance of the high-voltage line is proportional to the battery voltage and capacity used._x000D_ 2. Experiment from short to long when testing the arc distance. It is strictly forbidden to exceed the maximum arc distance when energized, because the high voltage energy cannot be released and the module is easily damaged._x000D_ 3. The power of the module is large, and the internal is not suitable for heat dissipation, so it is not allowed to work for a long time._x000D_ 4. The method 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._x000D_ 5. The two sections of small capacity lipo batteries are connected in series at 7.2V. The measurement voltage has dropped to about 4V in the arcing state. The smaller the capacity, the lower the voltage. Therefore, it is recommended to use lipo batteries above 2000MA, and it is best to match batteries above 4000MA if possible.
