Make Your DSLR Camera Run Four Times Longer with a DIY External Battery System

If you don't want to be tethered to an AC cord and your DSLR battery doesn't have an option for a supplementary external battery, the folks at DIY Photography show you how to connect two batteries to make your camera last four or five times longer.

This project requires some wiring and soldering work, as well as taking apart a lithium-ion battery, so you'll need to take care (standard disclaimer: Know what you're doing or things could explode). The instructions, however, are thorough. Basically, you hack a "sacrificial DSLR battery" and connect it to an external high-capacity DSLR battery.

This gives you the ability to do long time lapses or otherwise shoot for longer than you normally would without needing an outlet nearby.
