Limited Amps on Input - 06.29.2005, 02:36 PM

Here's a question to you electronics folks:

If your batteries were physically limited to less amps than your speed control and motor wanted to pull, what happens?

I ask this because I've learned that the new FMA lipos I bought have a note with them that specifically says that their wiring limits them to 60 amps, even though they are capable of more. I assume this means that the pack will only offer up 60 amps regardless of what is being demanded of it. If this is true, that's a great way to help ensure lipo safety since my packs should be physically capable of 128 amps, but are limited to 60. That should mean they would never overheat because they never get pushed too hard. However, I'm curious...

With that in mind, what happens when the speed control and motor want 100 amps during heavy accelleration or other spikes? Do they just operate on the 60 amps and not run as hard?

I'm expecting to get some first-hand experience this weekend, but I was hoping that someone else might have a good idea before I blow something up! :)

Electronics run on smoke... if you let the smoke out, they stop working.
