SBrick squeaks in the forum
Support
Hi, I just got SBrick and installed it on my MOC car. (I didnt' test it with LEGO IR receiver) The car runs with 2 LEGO PF L motors directly paired and a servo motor. And its weight is about a Kg.
At first, the car runs like 5 to 10 meters without any problem but it slows down gradually and finally stops. If I try to run it afterwards, the SBrick squeaks and the batty LED blinks and nothing moves.
It works OK if I lift the chassis and run the wheels in the air, of course.
On the other hand, I tried to short the current limiter fuse in the LEGO AA battery box (mine is manufactured in 2013) but my AA battery box didn't have any current limiter installed. No, fuse but only C1 and R1 was soldered there, unlike here:

So, I'm kind of stuck here... I tried to install 2 XL motors on a different model with similar weight (a bit heavier than this one) but the same squeaky thing happened.
Is the squeak noise an internal current limiter alarm installed in SBrick?
