100 Watts 12 Volts Mono Suitcase change connection

Hi,

On the Renogy 100 Watts 12 Volts Monocrystalline Foldable Solar Suitcase, can someone tell me where to buy (URL?) a cable to swap out the alligator clips to O-ring battery terminals?

I am wanting a more convenient and faster way to connect the panel to the battery bank as it is under the stairs in my Class A motorhome.

I was thinking of a 'permanent' cable from battery bank to outside edge of coach with some type of adapter that I could just plug into.

It can't be that hard, but I can't find a cable anywhere.

thanks

Paul
