ESC compatibility (Will it work?)
 

Hey all, I have a question that is specific to ESCs and amperage. I recently got ahold of one of the Chinese 1/14 Hyper Go H14BM trucks and its a kick in the pants. Super fast, durable, and comes with a ton of extras and spare parts for the inevitable breakage. However, In an effort to improve control and use one tx with all my cars, I wanted to pair it up with my Flysky transmitter and make it work a little better than stock. I was successfully able to install the rx but I found that the stock 45A ESC only has a momentary push button to turn it on and off and is not really programmable or able to be calibrated to the new tx. For the moment, I am looking to borrow a Hobbywing ESC I have in another 1/14 car since it can be programmed and calibrated. The concern I have is that it is only a 25A. Here are the specs I can find for it:

Cont./Burst: 25A/90A
Resistance: 0.005 ohm
Motor Limit:
2S Lipo 6 cells NiMH: On-road:≥12T; Off-road: ≥18T; 2040Size Motor
3S Lipo 9 cells NiMH: On-road:≥18T; Off-road: ≥24T; 2040Size Motor
Rating Voltage Of The Stock Cooling Fan: Without Cooling Fan
Built-in BEC: 6V/1A(Switch Mode)
Program Port: Rx Wire
Dimension: 36*28*21mm
Net Weight: 38g

As mentioned, the stock ESC says: "Smart 2S/3S ESC with heatsink" (As far as I can tell: "smart" just means that you can push the button on it five times and unlock a faster mode.)

Here is the info for the motor that I have gotten from the manufacturer:

2852 4400KV
Maximum operating voltage: 12V
Resistance: 20mR
Maximum power 354W
Rated power: 145W
Rated current: 15A

So... I have put in the different ESC and connected a heat sync to the top. It seems to be working fine but Im a bit worried about the difference in Amp ratings. I will only ever be running 2 and 3 cell batteries in it and from what the ESC says, it is rated for 2S/3S so all of this is just to ask if it will safely work for this setup? It seems crazy that the stock is rated at 45A and the Hobbywing at 25A and should work but Im still fairly new to a lot of the technical stuff for motors, ESCs, and those specs.

I should also specify that Im not competing in any kind of races nor will I be really pushing it though I will be using it to some degree offroad and average guy jumping thrashing/bashing.

Thanks in advance for any assistance.
