A Deans connector is just a type of electrical connection. Its popular and has been around for a while - some refer to it as a T type plug. It uses 2 blades that are turned 90degrees to each other to lessen the possibility of making a reversed polarity connection - which usually has disasterous results.

Usually you match the connection you get if you're starting out. Once you have a preferred connector, then you change them as needed.


BTW, the Accucel-6 is available from HobbyCity's USA warehouse, it costs more, but then there is no long wait for int'l shipping. I got mine in 4 days.
