Input power:

3.7V Li-ion battery can be used 1 or 2 section , such as 18650 , idle cell phone batteries ( to remove the for protection board , Recommended capacity of 2000mAh or more ) or NiCd / NiMH battery pack , 4V or 6V Lead Acid batteries.
This module is a small production with high-pressure science inverter transformer / booster finished module, the input terminal DC3V-7.2V voltage can get 200,000 volts for DC high voltage ( about 1-2cm arc ) at the output can be used as high school science experiments , electronic equipment, negative ion generator, high voltage source to use when making small science .
Caution:

To avoid high-pressure high-voltage module load electricity use . Must adjust the high voltage side suitable distance(before electricity, battery voltage and capacity is proportional to the distance from high-voltage arcing used when testing the arc distance from short to long experiment , prohibited from beyond the arc when powered up , the energy can not be released due to high pressure , easily damage the module.
