I have made a simple, battery power supply, which, can be used either as a dual ( + - 3.7V ) power supply or a single ( 7.4V ) power supply.
This can be used for anything. Tested and used with Danelectro FAB Metal distortion and overdrive.
The chassis can be connected either to the middle point or to the negative point of the 18650, Li Ion batteries.
The device is simple, just a couple of batteries and a couple of switches, no electronics, nothing else electrical too. However, the device has been found to be very useful.

Just a thought, two polyfuses could be added to protect from short-circuit? The same idea can be used with two PP3 9V batteries for +/-9V for higher voltage opamp circuits.
