New injection molded extensions with the Deans and Multiplex ends on them. As you can see disconnecting them is no longer a problem. In the past they were hard to do without putting strain on the solder joint. Also there are no more issues with corrosion. It is a small but significant improvement to something which has been and ongoing problem that we all put up with. They will be available in 6, 12, 18, 24, and 36 inch lengths.
Any of our batteries which use 16 gauge wire and deans or Multiplex will also have the same connection.
