To switch or not to switch ?

flaxbybuck Opening post 3 years ago

I wrongly entered my last post in the 'how to' section where, it seems, you are unable to respond. So here is my query for which I am seeking your guidance.

I have a motor circuit that comprises : 5S 5000mAh 30C Lipo; 40A fuse; 90A marine ESC; 3 x 20A fuses; 46 x 50 870KV brushless motor. There are no switches in the circuit yet.

1.Should I have a switch serving the battery ?
2. If yes, what rating ?
3. Should I have a switch between the ESC and the receiver ?

Any advice or guidance gratefully received. 😉

Len - thank you so much for your help.
You have put a name to a device which I somehow hoped would exist. This has enabled me to further research and successfully shop for one.
The use of this car audio circuit breaker will take the place of my in-line fuse and also be switchable, thereby enabling me to switch the battery on or off without taking up any more space in the boat. I also discovered that these circuit breakers are available in a range of sizes (amperage) going up into the stratosphere ! In my case the 40 amp size is costing less than £8. 😉
