Hardware overview
Battery
This is the first TTL trigger on the market with a user-replaceable battery.
It uses a standard LQ-S1 battery (commercially available), but only one specific type is compatible—please check connector type before purchasing.
This battery can provide power for approximately 6000 shots, assuming the camera’s sleep mode is enabled.
If sleep mode is not enabled and the camera remains active continuously, the battery may discharge within 5 days.Battery capacity and charge level can be checked via the software, but you can also get feedback by pressing the SMART button on the back of the i-TURTLE 3 trigger.
It’s recommended to turn off the camera first, then power cycle the TURTLE (off and on again). The trigger can remain connected to the camera.
Then, press the button and observe the number of LED flashes below the SMART label to determine the battery level.
