15 Wh Battery

This 15 Watt-Hour Lithium Polymer battery outputs 5 volts at up to 1A to power a GoPro camera or other accessories. The USB Battery Pack has a selectable Always On operating mode that is required for long-term deployment using our Blink controller.

  • Under normal circumstances, the standard GoPro battery will last for one to two hours of shooting. The CamDo Blink controller can be programmed to turn the camera off between shots to only have the camera powered on when the footage is needed. However, while Blink can extend the length of time the camera can be deployed on a single battery, the total amount of time the camera can remain powered on is still the same. The V15 battery increases the GoPro battery life by approximately 4x and has the Always On operating mode required for use with our Blink controller.

    There are a lot of battery packs available, however, don't be fooled by cheaper alternatives. Most of the USB battery packs on the market have an automatic power saving feature which turns off the battery if it is not continuously supplying power. Often, this feature is not even mentioned in the battery description, and only discovered when you find the camera's internal battery is dead, even though the high powered battery pack is still fully charged.

    Calculating battery life is non-trivial. It depends on the camera model, firmware version, SD card speed, lighting conditions, battery size, age of the battery, ambient temperature, and more. To help you understand the issues and to calculate estimated battery life, consult the Camera Power Consumption Study and our Time Lapse Calculator.

    Up to four V15 battery packs fit in our Weather Resistant Outdoor Enclosures and one V15 battery is included with our 6Watt Solar Power System. Up to three V15 battery packs can fit inside of our DeepEXT aluminum deepwater housing extension.

    The V15 comes with all necessary cabling to parallel up with other V15 batteries including the V15 that ships with our Solar system. See the FAQ's and Support tab on this page.

    settings_powerTwo Operating Modes

    • Always On mode that is required when using our Blink controller since it prevents the battery from automatically turning off due to inactivity.
    • Automatic Off mode will automatically turn the battery off after 20minutes of inactivity.

    • The battery is protected against failure due to overcharging, over discharge, overcurrent (short circuit), unusual voltage input, and temperature extremes.

  • Frequently Asked Questions

    How long will the battery last before it is discharged?

    It depends on many factors: the controller you are using, the camera you are using and the shooting schedule you have programmed. There are just too many variables to give an accurate answer.

    In theory, the 4,000 mAh V15 battery combined with the standard GoPro 1,050 mAh battery will give you about 5 times the shooting time.

    Combine multiple V15 batteries together in parallel (you can fit 4 x V15's in our solar enclosure to provide 16,000 mAh (60 Wh)) to give you that extra shooting time.

    An analysis of the power consumption of the various GoPro cameras and an explanation of how to calculate the theoretical battery life is outlined on the GoPro Power Consumption page. Our Time Lapse Calculator page can be used to assist you in planning the interval times of your time lapse project.

    How do I connect multiple V15 batteries together?

    Additional V15 batteries can be ordered for use with our Solar and weatherproof enclosures (4 x V15's can fit in our enclosure) for extra shooting time. All of the wiring to connect them together comes with the batteries. It just a simple matter of plugging them together as per our guide here.

    How many V15 batteries can fit in the solar or DRY weatherproof enclosures?

    Up to 4 x V15's can fit in either the Solar or weatherproof DRY enclosure. It just a simple matter of plugging them together as per our guide here.

    How can I tell when the battery is in Always On mode?

    It is easiest to determine the operating mode when the battery is disconnected and neither charging or supplying power to a device. When in Always On mode, if you double tap the power button a few times, the LED should continue to stay lit. If the LED goes dark between every other double press, you are not in Always On mode.

    How can I change the operating mode?

    To switch modes, hold down the power button for six seconds.

      • If the charge indicator flashes 3 times and stays lit for a second or two, you are now in Always On mode.
      • If the charge indicator flashes 3 times and then goes dark, you are now in Auto Off mode.

    If you are not in the desired mode. Press the button again for 6 seconds to change modes.
