Anybody seen these or tried them? They would need to be waterproofed but Im intrigued to drop the $10, waterproof it and see how they do. https://www.tindie.com/products/makervan/powerhub-xt60/
At 16A draw they're really not suitable for our purposes. I do have a solution though. These will be offered by SJS *soon* (not sure when but soon @bsgkid117) Solid copper bus bars with different plug combinations. Just solder together and then cut the connecting tabs to isolate the polarity.
Where is that "take my money" picture. I just made up a bus this winter with copper bars without easy holes.... Not fun.
