Arcing distance: 30 mm-50mm
Output of high-voltage length: approx. 92cm
High voltage bipolar discharge distance: 2-5cm
Dimensions(length*diameter): approx. 69.5*33mm

Attentions:

1. Please avoid the use of electricity at high voltage load, you must adjust the distance between the front end of the high-voltage power
2. Please test the arc distance from short to long, strictly prohibited exceed the maximum arcing distance if power. Because energy can not be released due to high pressure, it may damage the module.
3. Power of the module is high, the internal is not good for heat dissipation, so it can not work for a long time.
4. The method to determine whether the battery capacity can drive the maximum output power is to measure the battery voltage when the arc is pulled. If it is around 6V, it can output maximum power.

5. The small capacity lithium battery is connected in series of 7.2V, and the measured voltage has dropped to about 4V in the arcing state. The smaller the capacity is, the lower the voltage is pulled. Therefore, it is recommended to use more than 2000MA lithium battery, use with more than 4000MA battery is better.
