Is an anti spark switch necessary with hobbywing 150A ESC=

[emjas]

Hey builders!
Do anyone know if a anti spark switch is necessary for a 6s longboard configuration with a HobbyWing EZRun 1/5, 1/8 Scale 150A Pro Brushless ESC, or is it built in with the ESC?

you will get a small spark when connecting the batteries. at 6s it's not too big, but it will wear out your connector over time. Going to 8s/10s/12s you will see that spark really become larger.

Instead of a anti-spark switch (great but $$), i'd also look at a simple anti-spark loop key. Simple and easy, and cheap.
here's my how-to from a while back to make your own:
