Low Battery Indicator: The Kick will detect, and stop functioning, when a battery charge level drops below 3.2 volts UNDER LOAD (with an atty/carto attached). This is a safety feature. The Kick will tell you this feature is activating when you experience STUTTER VAPE (vapor-no vapor alternating – may feel like tss-tss-tss). If you continue to vape beyond this indicator, the Kick will stop functioning until a fresh battery charge is detected. If you remove the battery and meter test it (unloaded) it may read between 3.4 and 3.6 volts. There are many variables that can contribute to the various unloaded readings.
