Can I connect 4in1 ESC to motors without soldering?

I’m an electrical engineering student working on a senior design project to build a drone. We’ve chosen a 4in1 ESC, specifically the BLHeli 32. It can handle up to 60A, and we’re hesitant to solder the motor wires directly onto the pads because of the high current. Is there another way to connect the motors to this ESC? I’m new to drones, so any advice would be greatly appreciated!

You’ll typically need to solder the motor wires to the ESC pads—that’s standard practice. If you’re looking for guidance, you can check wiring diagrams for similar ESCs online. Many people start with soldering, and it’s manageable with a bit of practice.

Got it, thanks for the info! If soldering is the usual approach, we’ll make it work. I appreciate the help.

If high current is a concern, you could explore using connectors like bullet connectors instead of soldering directly. This might add a bit of resistance, but it allows for easier assembly and replacement.

If you’re using the BLHeli 32 ESC, it might be helpful to review the related GitHub issues to see if there are common problems or tips shared by others. It’s worth a look to avoid potential headaches.
