Battery Connector Usage Chart: Model Aircraft, Boats & Cars

There are many high quality types of connectors available nowadays for use with battery packs for model airplanes, helicopters, boats, and cars. A wide range of current handling capacities are required depending on the demands of electric power setups. Smaller park flyer types only might need connectors and wires that can handle 10 amps, whereas larger scale models and 3D helicopters can easily need more than 100 amps for acceptable performance. Connector failure is often the culprit in crashes due to inappropriate contact ratings. It is well worth your investment in time to research and implement proper connector usage considering the time and money invested in your model.

Specifications used for the following table were obtained from the suppliers. When making your selection, always add in a safety margin of at least 10%. For example if your application will draw a continuous current of 55 amps, then it would be best to use a connector rated at 60 amps or greater. Note: Connector images are not to scale.

(Seize the Day!)

Even during the busiest times of my life I have endeavored to maintain some form of model building activity. This site has been created to help me chronicle my journey through a lifelong involvement in model aviation, which all began in Mayo, MD. There is a lot of good information and there are lot of pictures throughout the website that you will probably find useful, and might even bring back some old memories from your own days of yore. The website began life around 1996 as an EarthLink screen name of ModelAirplanes, and quickly grew to where more server space ...
