Great plugs. They transfer energy well and are easy to install. They are easy to separate once they are in use, that is not the case with allot of the supposed good connectors. Some are almost impossible to separate once you plug your battery to the speed control. Great plugs, try em you will like em......................RT

I was pretty much satisfied with the performance of the Deans connectors I had been primarily using since I got into RC about 1.5 years ago. I was not very satisfied with soldering them, though. The YouTube videos make it look super easy, and I have done okay with them sometimes, but other times I just can't seem to get it right--I wind up with a sloppy solder, I melt the connector, forgot the heat shrink, etc etc. Now, I know it was probably all because of my lack of skill or a cheap soldering iron or whatever. I'm not blaming Deans. They are without a doubt the most popular connector and are a quality product, but maybe they are not for everyone.

So I decided to try these--even though I once complained to Horizon that I wish they would not use proprietary connectors! I am so glad I did. I soldered a battery and ESC in just a few minutes on the first try--with my poor skills and poor soldering iron!

I'm sold on these now and will use EC5's when I move to larger stuff. It also helps that my local Hobbytown has them in stock!

after years of usuing different connectors this is the best i have found and only discovered them when i ordered a new battery pack .
