Avoid power on when No load. You must adjust the appropriate distance for high-voltage terminal before power on, high-voltage line arc distance is proportional to the battery voltage and capacity.The test arc distance from the short to long experimental, It is prohibited exceed the maximum arcing distance(<1.5cm,1cm is OK). Otherwise, energy can not be released due to high voltage, easily damaged modules.The module power, the internal is not easy for heat dissipation, 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 battery voltage when in the arc state.Small capacity series lithium battery is 7.2 V, voltage will drop to about 4V when arcing, the smaller the capacity, the lower the voltage will become. It is recommended to use above 2000MA lithium, it is better to choose above 4000MA battery.
