It’s just an idea that can get better if refined; I’m talking about the Hungry Batteries. They’re not any power-chomping monsters, but rechargeable batteries that get slimmer and slimmer as they run out of juice. Essentially providing you a visual aid to indicate recharging time! The highlight being, easy removal from the cramped confines of a battery-house. No news on what kind of materials to be used for the casing, but I guess some kinda foam / sponge will do.
