Build Molex Micro-Fit 3.0 (MX3.0) male connector if needed

Female pins are used in the male connectors. Orientation is important, they should click into place without excessive force, and should then be locked in place.

JST XH 2.5 (2.54)mm plugs can be built, but can also be purchased pre-built in bulk, though on Amazon they seem to be sold only with matching male connectors. Aliexpress has just the correct pre-wired female connectors.

Check the color of the wiring before purchase - it's less confusing if the wire colors match that on the battery when plugged in.
