Now you know why us hobbyists have bins, drawers, and boxes of extra parts. If youâre going to pay that shipping, at least buy way more than you need.
Eventually⊠you donât need to buy much of anything to prototype.

Do you have a suggestion for a standard connector for small wires? I'm a huge fan of Anderson Powerpoles for larger wires, but I don't have a go-to for smaller wires (e.g. those on little LiPo batteries)
What kind of voltage + amperage? Already have a wire gauge planned?
Without any info, Iâve enjoyed working with the XT line for basic power needs. Likely youâll just need
XT 30s, if dealing with 1-30 amps. Easy to solder, cheap, and theyâre keyed.
Though I am going to guess the ubiquitous but pain in the ass JST (PH or XH) might be what you really need. Low voltage + data.
I'm asking for projects that I haven't yet thought of yet. Probably 20 gauge or smaller and low enough amperage that isn't going melt the wire.
XT look like they can only handle large wires. I don't see any 2-pin JST connectors.
I want something like Anderson Powerpoles, but for smaller gauge wires. Something standard that I could attach to every small device and small battery that I buy so I don't have the "wrong connector" problem.
JST PH 2-pin is what youâre asking for. Regularly use them on 20-28 gauge.
There are smaller connectors, but they have fewer mating cycles and are a pain to work with (tho the ones I mentioned arenât fun, either). Would recommend 2mm pitch to start with.
Theyâre very common. Can get a set of 100 connectors for $5ish.
Literally search for âJST PH 2-pinâ. Buy a decent crimping tool to save some frustration. Worth the money.
Or buy a set of pairs (make/female) with existing wire leads to start you off and see if theyâll work.
