Disposable batteries are toxic, expensive and take up too much space in landfills. But they're also necessary because we still need to power our remotes, cameras, game controllers, gadgets and drones. That's where Pale Blue comes in. Their new Lithium Polymer USB Smart Rechargeable Batteries are more efficient, faster charging, and longer lasting than other rechargeable batteries and topping them up is as easy as hooking up a MicroUSB cable. You could even save a thousand dollars per battery compared with the cost of normal disposables. These might be the best batteries out there.
