That butt connector splice scares me. The crimp looks bad and there is too much exposed copper on the ends, there should be little to no wire visble, maybe 1/8in exposed or less.
It looks like you tried to crimp it with one of these = big NO! This tool is garbage, like a last resort to even strip wires with it let alone crimp. Will never get a good solid crimp with one.
Ideally you would want a ratchet type of crimper with removable dies where it will not release until the connector is fully crimped.
Or at least this, use this crimper with uninsulated crimp connectors. You could take those covered ones you got and cut the covering down the middle with a razor blade and remove the covering. Then crimp the connector.

Usually you should solder the ends of the butt connector as well. But just crimping should be ok.
Then you should use some adhesive line heat shrink tubing, the glue inside the heat shrink will melt and create a water tight seal for the connection.
