JST 2-pin cable
Red and black tinned wires with a 2-pin JST PH connector on the end. 4" / 100mm long. Matches up nicely with Adafruit's Lipoly charger!
Adafruit don't have the 'mating' version of this, with the receptacle - but they do have a long extension cable that can be cut in half.
New! Adafruit now use genuine JST PH connectors for these cables so they are easy to insert and remove. For more information about JST PH connectors, visit the JST theybsite
