Powerpoles are pretty great for inter connected modules. They require a crimper but you can put any number of them together to make a multi connector of wires. They are also not male or female, they all plug together so no mistakes. I would get the 30A size. The plastic bodies are the same for these lower currents, only the metal connector inside is sized to fit different gauge wire. And different gauge sizes will also plug together. There are about a half dozen colors or more
There are many sellers, so look around, here’s one
