Remote switch & Circuit breaker

[Gilbert Pun]

Like to welcome ideas the design on how to put in Remote switch & circuit breaker on big off shore boats for 15S or more.

Stick a HEV battery kill switch through the deck. https://www.evwest.com/catalog/prod...ucts_id=267&osCsid=383qbhnero6c3bkte7fhaimuf4

Or consider using an industrial relay powered by a small 3S lipo and electronic switch. https://www.evwest.com/catalog/prod...ucts_id=406&osCsid=383qbhnero6c3bkte7fhaimuf4

I knew Tyler would come up with something heavy duty. Lol

Thanks, Tyler.
Any one put anything on their big boats ?
Espectially RC control switch ?

Pilot a channel off the radio to control one of these relays to turn on power to the motor ESC.
-for a system under 60 volts use one of these.

if its over 60 volts you might need one of these

this also has a better current capacity.

We ran one of these contactors in our full size electric hydro. The speed control was rated at 2000 amps, but we didn't draw over 1000 amps in our runs. Fortunately it was donated and we didn't ask the cost. Tecknowledgey carries many smaller contactors and switches.

Not to my knowledge Gilbert. The higher current contactors are quite heavy and large and would only fit in the really large boats.
Ideally you also need a soft-start circuit to reduce the arcing in the contactor when it closes and instantly charges the caps on the ESC.
I have welded these contactors shut in HEV's when the soft start was accidentally not used.

Thank you, Guys, for all your input.
