Julet 4Pin 3pin 2pin Male Female Waterproof Cable Electric Bike Extension Cable Connector

The package has several complete sets. Both the male and female plugs. I needed to fix a light on an electric bike and these plugs fit perfectly with the factory plugs so I would say 100% compatible. The connection is tight and seals nicely. I have no doubt they will keep moisture out. I Do Not know if they are submersible. The quality appears to be equal to the original, no concerns to be noted so far. Functions as expected. The diameter of the whip was slightly smaller than the original. Got to me quickly.

I'm very very pleased with this purchase because of the fact that when I've read other reviews they were saying you only get one cable this actually came with multiple cables which I need for multiple applications I used one as soon as I received the package which the package ride very swiftly by the way this item worked perfectly the first time solved my issue right away I would definitely recommend this item if you need it for your bike

I needed one to repair an ebike brake switch. Worked great. Would probably also work for dynamo lights.

Great

Works just fine

I bought these to make an extension so I could have two output plugs with voltage on my ebike. These fit snugly so they will be waterproof. The wiring appears to be the same gauge as the original output wiring coming out of the controller.

Not a power supply cable for ebike battery charger. Very small like a speaker wire or something . Cheaply made wast of time and money. Going back to amazon

These cables work, but the sheathing on the individual wires melts far too easily. When I attempted to add heat shrink to the connections I had made, the heat from my heat gun melted the sheathing on the wires. If you have a hot air tool, or a variable heat gun, I suggest that you turn it down to a medium or low setting before applying shrink wrap.
