External Battery System for Cameras
Free Gift

  • £31.00

The Camtraptions External Battery System dramatically increases the life of a remote or camera trap set-up by powering your camera with a larger capacity battery.

The system consists of a dummy battery, which is inserted into the camera's battery compartment, and a Compact NP-F Battery Adapter. This NP-F Adapter is compatible with the popular Sony NP-F battery type. The major advantage of this system is that a range official and third party NP-F type batteries are available in a variety of different capacities and sizes. The largest NP-F970 battery has a capacity of around 8,800mAh!


  • If you do not need the dummy camera battery, then you can buy the NP-F Battery Adapter on its own here.
  • If you just need the dummy battery and not the NP-F Battery Adapter, then you can exclude the NP-F Adapter by selecting the "NP-F Adapter Not Included" option above.

Key features:

  • The system can provide a significant increase in battery life for your camera. For example, when paired with an 8,800mAh NP-F970 battery the life of a typical camera can be increased up to 8x!
  • Adapters available for a large range of digital SLR and mirrorless cameras.
  • The camera’s existing battery life indicator can be used to check the remaining charge.
  • Fits into our Camera Housing even when used with a large NP-F970 battery.
  • The high-quality coiled cables offer a maximum extension of 110cm.

How much longer will my camera last? 

It is possible to work out the increase in your camera's battery life when using the External Battery System. Find out the capacity of your existing camera battery (it should be written on the battery itself and is measured in “mAh”). Then find out the capacity of the NP-F battery you want to use, measured in “mAh”. Divide the NP-F capacity by your existing battery’s capacity. This will tell you how many times longer the camera will last when powered by the External Battery System.

What's Included? 

1x dummy camera battery and cable

Optional: 1x Compact NP-F Battery Adapter

The NP-F battery is not included and must be purchased separately.
