Features: High-voltage module should be used to avoid high-voltage no-load power, power must be adjusted before the high-voltage line of the appropriate distance, high-voltage line arc distance and the battery voltage and capacity is proportional to. The test arc distance from the short to long experimental, power is strictly prohibited beyond the longest arc distance, because the high-pressure energy can not be released, easily damaged module. The module power, the internal should not heat, so it can not work for a long time. To determine whether the battery capacity can drive the maximum output power is the way to measure the arc when the battery voltage. If you can drive about 6V maximum power. The small capacity of the two series of 7.2V in series, in the arc state measurement voltage has dropped to about 4V, the smaller the capacity of the lower voltage pull. It is recommended to use more than 2000MA lithium, the best condition with more than 4000MA battery.
