So I have this recorder that likes to eat AA batteries for breakfast. I need to buy something way more efficient, but it may come at a cost. But must it?
The setup I'm looking at right now is a IDX Lithium-ion battery coupled to the recorder via a cap that leads to the DC power in. Pretty standard setup; these batteries are used to power all sorts of pro gear, such as video cameras and audio mixers. Cost is an issue, though, as these batteries can cost up to $200 each, and the chargers are nearly $400.
So who's figured out a cheaper way of doing this?
