My power cable is failing

Post by akbarhash »

Hi. Maybe this is an isolated problem but my power cable keeps failing. I had the original one go some time back. Then I soldered it back horizontally but that too failed twice. Now I have gotten new walkera cables, with I will admit a smaller gauge wire, but this time i soldered it correctly by sending the cable through the holes. this too failed in a short period of time.
I am using the crazyflie a lot, to do some testing but the cables are causing me frustration. Does anyone have any suggestion. The last thing I can think of is to install some right angle pins then attach the wires there as I am afraid I might do damage to the crazyflie if this keeps going on.

What do you mean by "failing?" Is the solder joint breaking or is the cable coming apart? If the solder is breaking, are sure you're getting a good solder joint? The solder is pretty much 100% of the mechanical force holding the cable so it can't be a cold joint...

I mount my battery in a reverse position to take up some of the slack in the cable. It also reduces the stress on the solder joints. Maybe this will help you?

The cable is coming apart at the solder joint. I feel there needs to be some reinforcement at this point apart from the solder.
