How to avoid short circuit of mechanical and electronic smoke?

1. Always check the resistance and short circuit of the atomizer. Different from the general finished electronic cigarette, the mechanical electronic cigarette can ignite even when the atomizer has a short circuit. Here, the resistance value of short circuit refers to zero or close to zero, but most finished e-cigarettes will not make the resistance value lower than 1.5 ohms (Ohm), which ensures that the battery will not be under excessive pressure.

When using a new atomizer, be sure to check the resistance value of the atomizer first, and then screw it onto the mechanical battery compartment after confirming that there is no abnormality.

If using RBA assembled atomizer, do not let the resistance value be too low, because too low resistance value will make the battery pressure too high. It is best to control the resistance value between 2.4 - 3.0 ohms at the beginning to ensure safety.

Although the atomizer is not easy to be short circuited, it is better to use a multimeter to measure it. The specific test method is as follows: take out the battery, connect the battery compartment with the atomizer, place one probe of the multimeter on the positive pole of the battery compartment, and the other probe contacts the surface of the battery compartment (note that it is not the negative pole of the battery compartment). If the multimeter shows a non-zero resistance value, it means that there is current passing through, so there must be a short circuit somewhere.

When using a multimeter to test the resistance, it should be noted that the lead of the multimeter may also generate resistance. We have seen some very cheap multimeter, the lead resistance is even higher than 0.6 ohm. The lead resistance can be displayed by touching the two probes of the multimeter. When testing the atomizer, you need to subtract this value to get the true resistance value. For example, if the resistance measured by the atomizer is 2 ohms, if the lead resistance is 0.6 ohms, the real resistance is only 1.4 ohms.

2. Avoid running out of battery power. Another possible cause of battery damage or even fire is that the continuous discharge exceeds the discharge threshold, which means that the battery is too clean.

A lithium battery usually has 4.2V when it is 100% full. When the battery is used, the voltage will decrease. When the voltage drops to 3.6V or even 3.3V, you can still use the battery safely. But the safe way is that when the battery voltage reaches 3.6V, you'd better stop using the battery and charge it as soon as possible.

If you are not familiar with your battery, you should always measure the battery voltage with a multimeter to see how many times the voltage will drop from 4.2V to 3.6V. This can help you estimate battery power without a multimeter.
