These solid 2.5mm pitch connector cable pairs are great when you need something that can carry a couple amps of current, easy to connect and disconnect, and is just-about 0.1" pitch compatible.
These cables are nice and long, 20 cm each, in fact. They've got both small form factor and are a matching set, with an inline socket and plug connector. The two friction lock to make easy-breezy connections whenever you need light and small connectivity.
The two cables match with each other and with any JST XH compatible connectors. Wires are stranded 26 AWG.
Important: There appears to be no standard to JST-style wire connectors, some batches will have the red and black wires in a different order. ALWAYS check polarity before using! You can easily swap the wires with a pin if required.
