Frequently Asked Questions
Q: What battery does the 15KV high voltage arc ignition generator DIY kit use?
A: This kit is designed to run on a standard 18650 lithium battery with an input voltage of DC 3.7V to 4.2V. It can also accept up to 12V input, but doing so requires increasing the base feedback resistor to approximately 1.5KΩ — failure to adjust the resistor may damage the transistor or transformer.
Q: Is this kit suitable for beginners in electronics?
A: This kit is best suited for intermediate-level electronics hobbyists or students with some prior experience in circuit assembly. The circuit is straightforward and well-documented, but the extremely high output voltage demands a solid understanding of electrical safety. It is commonly used for high school science experiments, negative ion generator projects, and electronic research builds.
Q: What is the maximum arc distance produced by this boost step-up inverter?
A: 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.
