To provide an alternative to Anderson Powerpole connectors, since my team dislikes them due to them needing special crimpers to get a good seal and generally wanting higher gauge wire than FRC is supposed to use.
An alternative is
XT60 connectors. You solder on the wires so you don't need anything special to get them on and you can remove the wires if needbe. They're not patented either so they come from a lot of different suppliers.
