You can get them pre crimped like this if you don’t have a quality crimp tool. If you don’t go with this route. If you need to make like 200+ connections consider getting a quality crimp tool and then the crimp ends and housings, bonus there is no potential failure from solder joints (just from bad crimps since you will most likely not buy the 450€ JST WC-240 that is the official crimp tool. Tbf the engineer PA-09, which is what I use, is pretty solid once you get the hang of it and much more reasonable at ~ 30€. They don’t ratchet and they’re slower because they don’t have the wide dies but the crimp shape is very high quality, which matters. Just don’t get the ultra cheap unbranded or noname ratcheting crimpers with shit dies that cost like 10-15€ and give you bad crimps that fail 40+% of the time)
