ouch, so sorry, that was unclear, I meant the connector on the battery going to the fridge. My mistake. I meant that the way you set up the PP with the shrink wrap seems to waste a lot of space since it goes straight out from the battery. It looks very professional as it is, indeed, nice, but I would just bend the wires coming out of the PP, and try to support/wrap them somehow, if even necessary. So it basically looks like your fridge (yes) plug, so much more compact. TBH, I have lots of PP connectors on cables without any shrink wrap whatsoever and they are just fine. But, eh, if you have the room, then enjoy the beautiful shrink wrap and sheath job!
