In a previous post I talked about strictly using Powerpole electrical connectors. The only problem that I have encountered is when I try to separate two connectors. When putting them together one slides up into the other using the slots on the side. Sometimes when you try to reverse the process it doesn’t work so well. So I use a couple of pliers or a small channel wrench. Works great. Haven’t broken one yet.
Never liked to solder. When I first started flying electrics I was using Dean’s connectors. And at some point you probably need to solder connectors to ESC’s or batteries or something. Many years ago I discovered Anderson Powerpole connectors. I was attracted to them because NO SOLDERING!. The connections are crimped instead. If you have ever used a wire crimper before you can figure out what to do. If not, there are many Powerpole tutorials and how-to’s on YouTube. Besides not needing to solder, the other benefit is that while very secure, they are easy to connect and disconnect. You hear a little click. And after more than 15 years of using them and many hundreds of flights I have never had a problem.
