The adapter opens up the battery market for owners of a PowaKaddy Freeway 3, Freeway 5, or Freeway 7 trolley by featuring a 3-way connector at one end and a conventional 2-way battery connector at the other. So batteries like the outstanding lithium CaddyCell can now be used, meaning Freeway owners can upgrade to the best quality battery on the market rather than being restricted in their choice.
