I second the recommendation for PowerPoles. They work well, they're easy to connect and disconnect, they won't be confused with connectors for other things, and a lot of the ham radio community has standardized on them. The only downside is that the tool for assembling them is a bit costly (around $50); if you only have a few to do try to borrow the crimping tool rather than buying one. (That's the price for the crimping tools from ham companies. The official Anderson ones are a LOT more expensive, so don't buy those.) Those Philmore connectors are PowerPole clones. At the sources I checked (Amazon and eBay) they cost more than real PowerPoles from the usual ham sources (PowerWerx, Quicksilver Radio, West Mountain Radio), so there is no reason to buy them. All three of the ham companies I named are good sources; if you run into any of them at a hamfest you can buy from them with confidence. You can also buy PowerPole components from Mouser, but you have to buy at least 100 at a time for them to be cheaper than buying from the ham suppliers. They sell the parts separately; you need a black housing, a red housing, and two contacts to make a complete set. There are two different versions of the contacts; one with round ends with a slit and another with vertical tabs. For crimping with a tool you want the round ones. The PowerPoles that hams use come in 15A, 30A, and 45A versions. The housings are the same and they all interconnect; the only difference is the size of wire that the contacts are designed to accept. If you try to use a small wire in a high power contact you won't get a good crimp; if you try to use a big wire in a low power contact it won't fit. Power handling capability is limited to the lower of the ratings in the connection. There are also larger PowerPoles for higher current connections; they don't mate with the 15A-45A versions. If you want to use PowerPoles for something other than DC power connections in the 12V neighborhood, you should make them distinct from the ham power connection standard in some way. Use different colors, a different configuration of jacks, whatever. That way nobody will plug your other thing into a 12V power supply. The best prize I ever won at a hamfest was an AndyCrimp - the old dedicated version, not the Pro with interchangeable dies. Not quite up there with getting a KX3 but it's been very useful.
