RC Pro Plus has been at the forefront of battery connector development for years. Providing high quality, and high reliability, RCPP has quickly became a leader within the industry. 

Meet the "REB 7808 S.T" aka S7 Solderless connetors! Solderless? Absolutely! Solderless connections are more commonly found in applications outside the R/C industry, and inherently provide lower point of fatigue within the connection. 

The RCPP Solderless connectors are built with the ability to install the connectors to each application in minutes. With the bare wires exposed, each bullet connector utilizes 2 setscrews (180 degrees apart), to create a secure mechanical connection.

RCproplus SOLDERLESS connector tips.
These are my tips that work for me and have not necessarily been approved by the manufacturer.

The instructions on my bullet package says they are for 8-10 awg applications. The wires that I have on my esc and lipos are both 10 awg. For me the bullets work fine with the longer set screws that come with the bullets(older packages may come with shorter set screws). So if you have the longer 4-5mm set screws you should be fine with 10 awg with no modification.

However, If you want more security when using the 10 awg or smaller guage you can fold the wire back on itself to create a larger gauge to insert into bullet, thus when you insert the set screws it creates more mechanical pressure against bullet. As you tighten both set screws, it pushes the wire on each side against the inside of bullet surface. Also since the inside surface is threaded, it will result in greater security from pulling out.

Also you will note that there are two set screws to be used in each bullet, one should be flat and the other with a pointed end.

To prevent the set screws from loosening, I create a slight burr on the threads of both set screws so that they won’t unscrew by themselves(don’t over do this by creating too big of a burr!). The reason I do this instead of using loctite is due to the fact that I want the set screw to be conductive, and using loctite on threads could be an insulator. I want as much conductivity as possible and that means wire to set screw to bullet.
