Lopping off the ends of the power connectors on your brand new gear may not sound like a good idea, but it probably is. Anderson Powerpole connectors have become the defacto standard for power connections in amateur radio. They are easy to connect, and come in a variety of amp ratings and colors. It is the power standard for ARES/RACES teams, and a quick, safe, way for hams to come together, and share power at an event or emergency. The connectors themselves are fairly inexpensive. But you will want to make a one-time investment in a proper Powerpole crimp tool. They are about $40-$50. Powerwerx has a great selection of Powerpole connectors and accessories. They also have an excellent tutorial page on how to make proper Powerpole connections. Check it out!
