A small PCB board to use as a 3-volt power source for small LED projects. It uses a 2450-coin battery, an on/off push button switch, and a junction block for connecting your LEDs. The back of the board has double-stick tape for easy positioning and an easy pop-out battery holder for easy battery replacement. Great for all your DIY LED projects. Very similar to 708-1, but the 2450 battery will last approximately three times longer than the 2032 battery.
