I used very similar terminals on Ankle Wreacher. I crimped all the joints with a hydraulic crimper and haven’t had any issues.
I pulled 350A from the board last night, 8~10v of sag. Most of which was probably the battery haha(not drop across the terminals)
If you did want to solder them, make sure you continue heating it after inserting the wire to bring the wire up to molten solder temperature. Just inserting the wire into a pool of molten solder will cool down the solder without heating up the wire, leading to a cold joint.
