Over time, this spark erodes connector contacts, causing resistance buildup and potential failure. An anti-spark switch uses MOSFETs to gradually ramp up voltage, eliminating the spark entirely. It also gives you a safe, convenient way to power your build on and off without disconnecting the battery.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: What is the actual continuous current rating — 100A or 200A?\u003c\/strong\u003e\u003cbr\u003eWith the factory aluminum heatsink, the switch is rated for \u003cstrong\u003e100A continuous\u003c\/strong\u003e. To achieve \u003cstrong\u003e200A continuous\u003c\/strong\u003e, you need to attach an additional external radiator (recommended size: 20×12×1.7cm). The 1200A peak rating applies to brief inrush spikes only (milliseconds). For most electric skateboard and eBike builds, 100A continuous with the factory heatsink is sufficient.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: My ESC has large capacitors. Will this switch work?\u003c\/strong\u003e\u003cbr\u003eThe switch is designed to handle ESC capacitor inrush, but output capacitance should be kept \u003cstrong\u003eunder 6,000μF\u003c\/strong\u003e for reliable operation. If your ESC or power distribution has higher capacitance, the switch may not operate correctly. Check your ESC specifications for total capacitance. Most single-ESC builds are well within this limit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: Is there short circuit or reverse polarity protection?\u003c\/strong\u003e\u003cbr\u003eNo. This switch has \u003cstrong\u003eno short circuit protection\u003c\/strong\u003e and \u003cstrong\u003eno reverse polarity protection\u003c\/strong\u003e. Always double-check polarity before connecting (red\/positive to IN+, black\/negative to battery negative). Never short circuit the output terminals. A short circuit will instantly destroy the MOSFETs and may damage your battery.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: Can I use this switch for an eFoil or marine application?\u003c\/strong\u003e\u003cbr\u003eYes, the switch itself is compatible with eFoil voltage ranges (up to 60V \/ 14S).

This arc burns and oxidizes the connector contacts, can damage ESC capacitors, and in extreme cases can cause fires or explosions. An anti-spark switch uses MOSFETs to gradually ramp up the current, eliminating the arc entirely. It also gives you a safe, controlled way to power your build on and off without disconnecting the battery.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: What's the difference between 80A continuous and 200A max?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e80A continuous\u003c\/strong\u003e is the sustained current the switch can handle indefinitely without overheating (with adequate airflow). \u003cstrong\u003e200A max\u003c\/strong\u003e is the peak current it can handle for short bursts (e.g., during motor startup or hard acceleration). For sustained currents above 80A, attach a heatsink to the aluminum base using thermal silicone grease.

The aluminum PCB is corrosion-resistant, but the electronics must be protected from water ingress.

For sustained operation above 80A (up to 200A), a heatsink is strongly recommended. Apply a thin, even layer of thermal silicone grease to the back of the switch, then press the heatsink firmly against it. Secure with screws if the heatsink has mounting holes. Ensure the heatsink does not contact any PCB traces or components on the edges of the board.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: Can I use this switch with any battery voltage and ESC?\u003c\/strong\u003e\u003cbr\u003eYes, as long as your battery voltage does not exceed \u003cstrong\u003e80V safe operating voltage (20S max)\u003c\/strong\u003e. he switch is compatible with any ESC or motor controller — including VESC-based ESCs, hobby ESCs, and custom controllers.
