Hi all, I recently saw a very cheap motor controller on Aliexpress and decided to order it just to see what it would be like. As expected, I’m having a few issues with it, and was wondering if anybody here has experience with these no-name unbranded ESCs found on Aliexpress (unsurprisingly, the Aliexpress sellers haven’t been able to help at all and haven’t responded to my questions). I have two main issues:
the ESC is intended for a 6S pack, and I’m currently bench testing it with a 24V 2.5A PSU. When I power it on from the PSU, I always get a low battery warning (one out of four bars on the battery level gauge). Do people know how to configure such ESCs to avoid this error or is there some other workaround?
I’m still able to run the motor despite the low battery warning, and the motor spins up fine. However, when I pull the throttle back to enable braking, the motor will slow down and come to a stop, but it no longer spins up and the ESC just ignores throttle-up commands. After that, even though the motor won’t spin up upon pushing the throttle potentiometer to the max, I can still pull the throttle low and the motor will continue braking (which I saw because the motor required more force to turn).
Has anyone here experienced similar issues with their ESCs? If so, were you able to fix them?
Finally, does anyone know how the motor controller I linked above compares to the “generic eBay ESC” that everyone uses? (e.g. this one)
Any advice is greatly appreciated!
