There are a lot of Wi-Fi or Bluetooth enabled devices out there that can be turned on and off with your smartphone, but there’s no need for your devices to feature Wi-Fi or Bluetooth support if they are using Batthead batteries.
Battheads are Bluetooth-controlled, AA-sized rechargeable NIMH batteries with the ability to connect to your smartphones using a Bluetooth Smart Chip. Other than being able to switch on/off devices with your smartphone, your smartphone can even notify you if you unknowingly left your Batthead-powered device somewhere.
Still not enough features for you? Battheads can also turn on/off depending on the time of day, proximity to the phone or even depending on the ambient temperature. Then there are Battheads with an accelerometer, so when you move the batteries they will detect it. A device having this battery could come alive when you pick it up or turn off when it’s not being moved for a few minutes.
The smartphone app (iOS and Android versions are coming) will detect which set of batteries is being used in a device. So there will be no issues when you are charging one set and using another in a device. But we are not sure how the app deals with things when multiple sets of batteries are used simultaneously in many devices.
Interested in these unique batteries? Battheads will only reach production if the funding goal is met over at Kickstarter. If you pledge 19 CAD (US$18.40), you can get a Batthead without an accelerometer provided their funding campaign is a success.
