Like Molex there can be any number of pitch sized connectors made, your case its generic random "china" connectors made enmass (perhaps a sloppy counterfeit job)
Ideally you would just get rid of the Julet's and use regular, normally available connectors from your electronics/wire/commercial retailer who sells to commercial outfits but also sells to the public or find a local rc shop for bullet connectors, xt's, anderson pp's, rather then having to wait days or even a week or longer when ordering on ebay or amazon for some random, generic connector that may or may not fit due to the sellers inability to properly describe their product in the details section.
The good news is, 3 wires per connector. If its a battery or even to a certain extent a controller (capacitors still have juice in them), just dont go ahead and snip all at once, take the insulator material off first and snip each wire individually. You can roll the dice on the controller if your feeling lazy, but the battery up to you.
