Hi Mooch
If the voltage is too low, there may be a slightly larger self discharge phenomenon. The voltage at the time of shipment is OK, but after a long time of storage, the voltage of some batteries will slowly drop, such as 0.005v or lower every day.
At present, the technology of K30 has been solved to make the voltage more stable
Self discharge problems still exist in some brand batteries, but the proportion is much less than before, and lithium battery technology is improving
The K30 voltage in the video is lower than the cut-off voltage of the li-ion battery, which may have a little impact on the performance, but it is still safe. The built-in protection device is still in place. In case of short circuit or huge current output, the protection will be started, and the battery will fail. The explosion-proof valve device has nothing to do with the voltage, but with the internal pressure of the battery
Low voltage battery can be repaired by charger. The voltage is restored to the normal voltage and then used in some equipment
If the conditions are not met, it is not recommended to use
Low voltage will affect the performance of the battery, such as 3000mAh battery, the capacity of the repaired battery is only 2950mah
Pay attention to daily use, do not let the battery voltage too low,do not lower than the cut-off voltage
At the same time, the use of batteries will also cause performance loss. Li-ion batteries all have service cycle life
If the battery has quality problems, please contact the after-sales department
Thanks
