FLIPSKYAnti Spark Switch Aluminum PCB/CASE V1.0 200A for Electric Skateboard/Ebike/Scooter/Robots

This is exactly what I was looking for. Something that can switch on and off battery power to a controller without having a spark happen. This can handle up to 90 Volts and 300 Amps, and I am using it with a 72 volt battery system. It's heavy duty wiring is ideal for large connectors. If you wanted to use it with lower power rated systems, you can still use it, but would have to make sure you could use the 10 gauge wire into a connector that could accept that size of the wire. I am using lever connectors that can handle 10 gauge wires.

I believe this would be a perfect product if the included switch was rated for higher than only 24 volts I've already gone through damaging multiple other components because of this little birdie maybe they need to check their Mos for the build to see if they're receiving the wrong parts from whoever's putting these together for them

Stopped my vecs from being damaged but not my battery didn’t make it to the final build and use of my board but it is what it is

I have purchased two of these over the past few months working on my project and both of them have failed me after only a few miles of riding. Both of them worked great with my key switch for a short period of time before they would get stuck in the ON position, with no way of turning the power off even after unplugging my key switch from the board.

The component itself seems to be working OK.Only problem is, the description is incorrect - it clearly mentions 12AWG (and that's why I bought it), but the cables are actually 10AWG, which was really difficult to use on my XT60 connector.Would expect better description for such an expensive product.
