I have seen and heard that it is possible to attach a rechargable battery to my cortex controller. When I open up the back of the controller I cannot find a place to attach a battery. How do we attach a rechargable battery? Help please!
The only Batteries we sell for the CORTEX are re-chargeable and connect to the White Power Port next to the On/Off Switch on the unit.
Sorry, I meant the joystick for the cortex controller. I have heard that the same batteries that are used for the cortex controller can somehow also be used on the joystick. I would like to use the rechargable batteries because the AA batteries die way to quickly. Sorry for the confusion.
**We do carry re-chargeable AAA Batteries now for the Joystick. See http://www.vexrobotics.com/products/accessories/power/276-1696.html **
