It is commonly used for high school science experiments, negative ion generator projects, and electronic research builds.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the maximum arc distance produced by this boost step-up inverter?\u003c\/h4\u003e\n\u003cp\u003eA: When powered by a 3.7V–4.2V input, the secondary high-voltage output (without additional rectifier diodes or capacitors connected) can produce a high-temperature purple arc of up to approximately 1.5cm in length. The maximum rated output voltage is 15KV, which equates to roughly 1cm of arc distance — exceeding this limit may damage the transformer.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What battery does the 15KV high voltage arc ignition generator DIY kit use?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This kit is designed to run on a standard 18650 lithium battery with an input voltage of DC 3.7V to 4.2V.
