Additional functions of the board provided in the electronic battery mod (see "Battery mod").

— Varivolt. Battery mods that allow you to adjust the voltage supplied to the atomizer. Due to this, the power supply changes and, accordingly, the heating power and the general vaping mode are regulated. At the same time, unlike the varivolt (see below), the voltage change in the varivolt is carried out only manually, regardless of the resistance of the atomizer. In fact, this means that if the user wants to get the same power on an atomizer with a different resistance, he will have to reconfigure the varivolt.

— Variwatt. Battery mods with the ability to automatically maintain the specified power supplied to the atomizer. An automated version of varivolts, which is able to automatically adjust to changes in the resistance of the atomizer. The voltage in the variatt is set for a specific resistance of the atomizer; if the resistance changes, then the electronics automatically sets the voltage at the output of the battery mod so that the power remains unchanged. Thanks to this, you can put heaters with different resistances on the battery pack without worrying about reconfiguring the power parameters — the variatt will independently select the desired voltage, keeping the intensity of soaring at the usual level. The main disadvantage of this option compared to...the varivolt is the relatively high cost, and compared to thermal control(see below), the need to choose the power experimentally, by trial and error.

— Variwatt + Varivolt. Battery mods capable of operating in two different modes — varivolt or variwatt, at the request of the user. These modes are described in more detail separately, and their combination in one battery pack can be useful for those who appreciate the advantages of vari-watt, but are not averse to experimenting with vari-volt as well.

— Thermal control + variatt. Battery mods that combine the variatt capabilities described above with the thermal control function. Thermal control allows you to monitor the temperature of the spiral, maintain it at an optimal level and turn off the power when approaching critical heating. The combination of these two adjustments is the most advanced option for today, in fact, eliminating the need for the vaper to manually select the optimal power settings. At the same time, the steam turns out to be pleasant to the taste (both due to its own temperature, and due to the fact that the probability of burning the wick is reduced to almost zero), and the battery charge is consumed in an optimal way. A serious drawback of thermal control, in addition to a rather high cost, is limited compatibility with atomizers: for this function to work correctly, a “head” with a coil made of nickel or titanium is required, and such models are relatively rare, and they are not cheap in themselves.

— Thermal control. Battery mods, the settings of which are limited only by thermal control. This function is described in more detail above; here we note that thermal control itself does not allow controlling the intensity of soaring, therefore this option has not received much distribution.

The ability to update the firmware of an electronic cigarette — more precisely, a battery mod (this is where all the control electronics are usually located).

This feature is most often found in models with advanced adjustments such as wattage or thermal control (see "Battery mod") — simpler devices do not require complex firmware (although there are exceptions). Major manufacturers of electronic cigarettes periodically release software updates for their equipment that improve the quality of work and eliminate errors noticed by consumers. So this feature is highly desirable for a device with extensive functionality and complex electronics.

The smallest resistance of the heating coil of an electronic cigarette.

The meaning of this parameter will be different, depending on which part of the device is in question (see "Type"). So, for atomizers, this parameter is given if spare heaters are supplied in the kit — accordingly, it is indicated for the “head” with the lowest resistance. For a battery mod, this is the smallest resistance that can be connected to it. And in starter kits, the minimum resistance is also usually indicated by the battery mod; low-resistance "heads" in such cases may or may not be included in the delivery.

Anyway, data on the minimum resistance is important in the mutual selection of an atomizer and a battery mod (including when creating custom windings) — connecting an atomizer with too low resistance is fraught with overloads and various unpleasant consequences, up to fire. However, this parameter is of particular importance for lovers of the so-called subohm — soaring at a low heater resistance (up to 1 ohm), which allows you to achieve high steam saturation (when the resistance decreases, the power increases). Not all batteries are capable of working with sub-ohm heaters, so the suitability of a battery mod for such vaping needs to be clarified.

The highest resistance of the electronic cigarette heating coil.

The meaning of this parameter will be different, depending on which part of the device is in question (see "Type"). For an atomizer, this can be either the resistance of the complete heater, or, if there are several “heads” in the kit, the resistance of the highest-resistance replaceable coil. For a battery mod, the highest resistance is indicated at which the battery is able to deliver sufficient power for operation. For the starter set, the data is usually given according to the battery mode, while the resistance of the complete heater (heaters) may be lower than the maximum.

Data on the maximum and minimum (see above) resistance is necessary, first of all, to select an atomizer and a battery mod that are compatible with each other. The atomizer must fall within the operating range of the battery mod, otherwise the battery will either be overloaded (if the evaporator resistance is too low), or simply will not provide the desired degree of heating (if it is too high).

The maximum power supplied by the battery.

This is one of the main parameters of the battery pack that determines its compatibility with the atomizer. Starter kits (see "Type"), by definition, include atomizers that are optimally suited to a given battery in terms of power, and this parameter is mainly of reference value. But when choosing components separately, you should pay special attention to it. Higher power allows you to achieve more saturated steam, but only up to certain limits — too much heating leads to a deterioration in taste, and even burning of the wick (which, all the more, does not contribute to improving the sensation of soaring). So the atomizer must normally transfer the power of the battery, otherwise, at best, you will have to constantly limit the power with the help of a varivolt or variwatt (see "Battery mod"), and at worst, normal use will be impossible at all.

Note that for classic evaporator tanks with one spiral, power up to 40 W is considered sufficient; more powerful batteries are designed mainly for advanced serviced models, drip atomizers and bacodrips(see "Type of atomizer") that have more than one coil and, accordingly, are more high consumption in terms of energy consumption. Also note that the actual heating power depends on the voltage, and in fact it may be lower than the claimed one, depending on the resistance of the atomizer. See “Maximum voltage".

The lowest voltage that the battery mod can supply to the atomizer.

The meaning of this parameter depends on the type of battery mod and the functions of the board (see above). So, in mechanical and simple electronic modes, the smallest value to which the battery voltage can drop before it turns off and requires charging is usually indicated here. Knowing this parameter, as well as the resistance of the atomizer, you can calculate the minimum guaranteed vaping power.

If we are talking about a mod with adjustments like varivolt or variwatt, then the minimum voltage is also the lowest voltage that can be set manually in the settings. This may be necessary to reduce the power and, accordingly, the intensity of soaring — for example, if the gas station has a very rich taste, and abundant dense steam would be overkill. In adjustable battery packs, the lower the minimum voltage (with the same maximum voltage), the wider the adjustment range, the more options the vaper has to adjust the vaping parameters. See “Maximum voltage".

The highest voltage that the battery mod can supply to the atomizer.

Knowing the minimum (see above) and maximum voltage, it is possible to estimate the heating power that the battery is able to provide at a certain resistance of the atomizer. For example, if we have a battery mod with a voltage range of 3.3 – 4.8 V and an atomizer with a 1.8 Ohm coil, then the current strength at the minimum voltage will be 3.3 / 1.8 ≈ 1.8 A, and at maximum 4.8 / 1.8 ≈ 2.7 A. Accordingly, the smallest heating power will be 3.3 * 1.8 ≈ 6 W, and the largest 4.8 * 2.7 ≈ 13 W. In this case, the nominal power of the battery can be higher, but not vice versa — the actual power cannot be more than the nominal. Let's say, theoretically, the battery from our example, combined with a 0.15 Ohm sub-ohm atomizer, even at the minimum voltage, should produce a current of 3.3 / 0.15 = 22 A and a power of 3.3 * 22 = 72.6 W. However, if a power of 50 W is claimed in the characteristics, then higher values \u200b\u200bare impossible to achieve, even if you unscrew the regulator to the maximum — at low resistances, the voltage at the battery output drops sharply.

The presence of a microUSB connector in the battery mode, through which batteries can be charged.

The main advantage of this feature is that it makes the battery independent of proprietary chargers. The microUSB standard is extremely popular in various portable equipment — smartphones, tablets, players, etc.; accordingly, a huge number of chargers, USB-microUSB cables and network / car adapters for such cables have been released for this connector. Thus, the battery mod can be charged not only from the "native" adapter / cable, but also from any accessory with the appropriate connector. However, note that all of the above applies mainly to models with non-removable batteries. If the battery is made removable (see above), then anyway it is recommended to charge it in a separate charger, and use the microUSB port only in case of emergency. This is due to the fact that in most battery mods for replaceable batteries, the boards are not designed for regular use in charger mode, and frequent use of microUSB charging can lead to premature failure of the board.

The presence of a display in the design of an electronic cigarette — more precisely, a battery mod (see "Type"): putting a display on an atomizer does not make sense for a number of reasons, in particular, because there is not enough space there. But on the battery pack, even a small one, it is quite possible to place a screen. Usually this is the simplest monochrome matrix (black and white or in another colour, say, white characters on a blue background), capable of displaying data in one, at most two lines. However, even with such equipment, control becomes more convenient and intuitive: a variety of digital and textual data can be displayed on the screen, for example, the set voltage or power value, operating mode (variatt / varivolt, if both are supported), battery charge, start message and the end of charging, failure notifications, etc. And some models may even provide advanced touch displays (see below)
