Make sure your firmware is up to date! We’ve made significant changes, improvements and bug fixes for most radio issues for capsule 2.0 & vision props. All your vision and capsule 2.0 props need to have the same firmware version to connect to each other, have the same modes, brightness and runtime, so make sure to update the firmware on all your props!

If your lights don’t run as long as expected, or appear to have very different runtimes, there are a few different possible causes:

  • They are getting old - you can email us for upgrade/replacement instructions. 

  • They are not all getting charged fully.

  • Your lights have different firmware or brightness settings.

  • Your lights are in different modes (some modes use more power than others).

  • The battery capacity is reduced.

  • The battery is draining when not in use. 

The best way to save power is to choose a lower brightness level, it can more than double your runtime. Setting the "auto sleep" function can also save a lot of battery life by dimming or turning off your light when it's not in motion. Brighter modes will drain your battery more quickly.


First, mark any light you suspect might be faulty to keep track of it.

  • Check your USB jack, cable and charger - click here for how

  • Make sure your lights all have the same updated firmware version, same brightness level, and are all in the same mode when testing.

  • Charge all your lights fully, and then remove them from the charger and let them sit for 24 hrs.

  • After 24 hours (or up to 1 week), check their battery levels: 

    • Hold the button down from off, the light will blink a color indicating its battery charge level - from red to green - until you let go of the button. Red is low, Orange is OK, Yellow is good, Green is great. 

  • If the charge levels differ significantly, there may be a fault, but the charge level detection is not precise, and your actual runtime might still be ok.

  • Check the runtime:

  • Firmware must be flowOS 2.0 or later 
  • Brightness level must be default: level 4
  • Updating the firmware does not change any settings, so you may need to set all the lights to the default brightness level by deleting the brightness level setting (hold past 5 red blinks, about 17 seconds)
  • Go to "bolder" mode (page3 mode 8)
  • Set a timer for 2 hours.
  • The lights should still be on after 2 hours. If any go out before 2 hours, the battery is either faulty, or if it's over 2 years old its capacity has reduced normally with age. 
  • If the battery is new and good, the runtime in bolder at default brightness will 3+ hours
  • It is expected for a capsule battery to lose about 15% and vision battery to lose ~30% in 1 week, while in standby as the light listens to the radio for button presses. After one week of standby, it will turn fully “off”, no longer respond to the 'group on' signals. Once the button has been pressed, it will start responding to group signals again. Since flowOS 2.6, we have introduced a "standby" setting on p5m6, where you can choose how long your prop will continue to respond to group on and auto-wake after you've turned it off. Here's more info on changing your standby period.
