Basic ESC question

[floatn turd]

New to the boat scene, If a boat needs a minimum of 100Amp ESC to run and I throw a 180Amp or larger, Is that going to be OK?
Is it a case of you can go over the AMP number on the ESC but not under??

Its a stupid question, I know..
Thanks

Welcome!
yeah, best to go overboard, NEVER under.
the 180A rating on the ESC is the most it can take, that doesn't mean it will try to deliver 180 amps. (in theory you could run a 180A esc on a tiny little 3A motor)
the motor will draw amps (not exactly but..) from the packs and the ESC will just deliver it (again not exactly) to the motor, if the motor wants more than 180 amps for longer than the ESC can take (ie the burst rating) then boom. Always overestimate your setup, ie your packs should deliver more than your ESC ((mAh/1000) *c rating) and yopur ESC should be more than your motor, kinda like taking a step up every time.
short answer: 1st q: yes
2nd q: pretty much.

No problems with extra headroom, the esc only supplies the current the motor will draw. If you choose the wrong prop the esc is capable of delivering enough current to destroy the motor., if you go the other way and choose an esc that can't handle the current the motor demands the esc will go up in smoke.

All questions are stupid, unless you know the answer.

Thanks for the info, I have one more question,

My set up runs on all "deans" are they that much worse for the "average guy" than the 5mm bullets? I'm no racer but if there is a big difference in performance then I will swap it all over.

Any thoughts??

It depends on how many amps you are drawing. If your setup draws no more than 60 amps then Deans are okay. More than that, go with 5.5mm bullets or larger. There is a downside to the bullets though, it is far easier to connect your ESC or packs with the wrong polarity. Solder them on with different polarity for male and female plugs. Usually, the negative on the packs is male, positive is female. Either way, always double check before plugging in.

I have seen highly experienced racers plug in wrong and toast $500 worth of batteries in a second.

I just Bought a Motley Crew boat, (stock) and I want to get the Genesis Offshore Brushless RC Twin Hull (1045mm) as my next project boat. So should I switch it all over to 5.5mm so I can swap stuff back and forth between the two boats??

Man I'm sorry, but this is my first electric build and I really think you need to be asking someone else. I don't know everything I need to know about my build yet, Sorry

Thanks for the info man, but I don't think I'm the one who posted the thread asking about types of connecters. But, this info falls right in there with info I'm going to need to know.

Thanks,
