I use batteries like this for my electronic work. I do fuse it, but what you have is a virtually unlimited current source at a voltage that never changes.

For + - ground supply, I hook up two batteries in series and now have a ground in the middle with a + and - 12 volt supply. FAR better than commercial power supplies - and the price is right.

Some solid state stuff, especially analog, wants a very stable power supply. Bread boarding and prototype with the above configuration makes it a LOT easier as I don't have to be concerned with the stability and cleanliness of the power (no spikes, no high frequency "fuzz" - just pure DC at it's best.


Happy new year!
