Which Speed Controllers For This Motor? Big Newb!
 

Hi, I'm not sure which speed controllers go with this fan motor,

If it says that the power is 252W or 16 amps then is that the max power it can handle safely and do I need speed controllers that are in the 15 to 18 amp range for safe efficiency?

Like would this be a good one?

Or maybe these are better?

I have this speed controller already but it's 25 amps so I'm worried about frying something.

Also is this battery good for the motor,

If I understand it correctly you're suppose to multiply the constant discharge which is "30C" by 2.65 for that battery and then that gives me about 80 amps constant, If I get a speed controller at 15 to 18 amps then will it safely handle the constant 80 amps or does it not matter if it's higher?

Thanks!

You will always want the battery to be able to handle more Amps then the Speed Control will take. Basically it means the battery can give up to a that amount of amps, and will give the speed controller what it wants up to that point.
