mah effect on esc?

[Daveknitter]

After minor problem with esc talking to great tech at Castle Creations he had said that he thought batteries i'm using 2- 5cells 5300 mah 65-100 dis. in series that i could burn out esc because mah was to small for esc, even tho have made over a dozen runs and everything is running perfect.(100-110 degrees over 53mph) Running Hydra ice 2,12 cell 50 volt max, leopard 5692 720kv in 40" dee vee.

Because your running a 10s boat on only 5300 mah and they require lots of power to go. My 4s, 6s and 10s boats all run 10,000 mah each because of run time and the speed controls are happier.

MarkF, Thank you for quick reply, total newbie to sport appreciate your imput.

Dave,

Higher capacity and higher C ratings have a stabilizing effect on the input DC voltage to the ESC. Almost all ESC's for the hobbyists do not have enough capacitors to handle the high ripple current. This is one of Castle's weaknesses for their current ratings. Higher capacity offers stiffer voltage reducing the dependence on additional caps. Short wires and good connectors also help reduce the ripple.

Tyler,

Thanks for reply, already have additional caps, good connectors, could make wires a little shorter, might keep everything as is can't afford new batteries and chargers at the moment, and considering being a newbie i think it runs great. thanks again. Dave

If you are happy with it, then don't changed anything...

Castle told me I needed at least a 1527 neu to move my little 32" cat......lol

I have found in the past castle will say anything on the phone . But, they could have been right

I run Castle ICE 200 aircraft controllers almost exclusively, and Tyler is 100 percent right, not enough cap capacity for safety. Their four caps simply have inadequate values for boats...same caps on the ICE 240 Hydras. I install five 1000 uF caps across the power leads, and pulling 260 amps my ripple current is just over one volt peak on 6S.

"If you are happy with it don't change anything" is a silly comment. The next time out the ESC may blow since this kind of damage is often cumulative rather than catastrophic. Adding an adequate cap bank (most commercial banks are pretty poor) can add considerably to ESC life and improve performance along with it. Do what you want but if you push your equipment then adding a good cap bank can be worth it.

Arrogance on display again....typical Jay Turner..

He says he's happy with the way it runs....never meant he should not add capacitors.

By the way Jay...every Castle controller should have extra caps added...it was a crappy design on Castles behalf from day one...a consumer should NOT have to add extra caps when they spend the money that Castle sold these ESC's for..but they are required. Perhaps they would still be making marine ESC's if they designed them correctly and didn't get a crapload of returns.

They put themselves out of the marine ESC business.

Welcome to my Ignore list....so sad that your personal attacks define you.

Believe your "silly" comment was a personal attack...

Also, years ago I was a proud member of your infamous "ignore" list...lets hope you actually keep me on it this time...many of us on here wear that as a badge of honor.

Just wondering.....how many people are on your ignore list?

What issues are you having with your esc??
I know several who have run Castle escs that no longer do.
the newer ones act like they have more problems vs the older speedos the used to make

I agree with this and was the big issue when the Brushless Revo first came out
