The paramount criteria in choosing digital technology and battery equipment rightly is functionality, reliability and operational efficiency. At the same time, as autonomous power supply technologies develop, manufacturers of the same mobile devices cannot but pay attention to the emergence of new approaches to organizing charging. Developers strive to make this process as easy as possible, thereby attracting consumers by this criterion. A rather unusual, although quite logical attempt to master this direction was made by the creators of the Opus BT-C3100 charger, an overview of which is presented below. The concept of universal charging was continued in this small device, but new features were added to it.
Instrument Features
The model is a small device designed to charge batteries and rechargeable batteries in four slots. Unlike similar devices, this modification allows you to work with a wide range of charge current indicators up to 2000 mA. Especially for working with nickel-cadmium and lithium-ion cells, the device integrates the optimal characteristics of the charge supply. Moreover, both batteries of different types can be serviced in slots at the same time. If batteries with high voltage are used, then a special switching on the control board is already required from the user himself. Also, the features that distinguish the Opus BT-C3100 charger from the total mass of analogues include the extensive inclusion of protective systems. The most effective among them is the ability to detect overheating and prevent the negative effects of a short circuit.
Main characteristics
One of the main parameters is the charging current range. It has already been noted that the maximum is 2000 mA, and the minimum is at 200 mA. In this case, the current unloading, valid only for lithium-ion batteries, is in the range of 200-1000 mA. The maximum charging capacity is 20,000 mAh, which is one of the best indicators in the class. At the same time, the device has very modest dimensions - 14.4x9.8x4 cm with a mass of 0.234 kg. As for the case, the Opus BT-C3100 is made primarily of plastic, but provided with modern insulation coatings. The model package includes only the power adapter and operating manual.
User's manual
In the process of using the device, the owner will have to deal with the LCD display, which will reflect the performance of the device. The display shows several display panels, each of which corresponds to a separate operating mode. The MODE button is responsible for selecting a mode. To activate the desired format of the device, hold it for several seconds. You can monitor the parameters of serviced items through the DISPLAY panel. In particular, it reflects the values of currents, voltage, characteristics of the battery fluid, etc. The charge current control element is separately presented - the CURRENT button is responsible for this choice. To designate a specific slot as active for control, use the SLOT button located on the edge of the Opus BT-C3100 panel. The instruction notes that a command with charging parameters can be given to each cell separately, and to all placed batteries at once.
Maintenance Instructions
The device requires a careful attitude, maximum protection against strong shocks, chemical damage and moisture. It is important to consider that even high-quality smart charges can lose their working qualities over time. This can occur, for example, in deviations of recorded indicators when analyzing the next battery. The best accuracy in the family shows a modification of the Opus BT-C3100 v 2.2. The manual recommends also testing it for all operating parameters. For testing it is also desirable to use high-level equipment with a minimum error. In addition, it is recommended that you clean the connectors periodically with special material. Salting of functional surfaces cannot be allowed, since such phenomena primarily affect the loss of accuracy of electrochemical measurements. In addition, the optimal battery charge time frame should be observed. Track them helps the same control panel with a display. The endurance of these standards is useful from the point of view of safety for the device itself and for batteries.
Positive feedback about the model
The device has a lot of advantages, which are not obscured by the rapid wear of the working base. Users to the forefront in this list display the omnivorousness of the device. It works with elements of various kinds, both popular formats and little-known ones. Moreover, the ability of the device to additional extended measurements with the same lithium-ion models is separately indicated. Only specialized equipment can compete in the efficiency of servicing this element. There are other advantages that attract the new generation Opus BT-C3100 v 2.2. Reviews indicate that even slightly damaged and damaged batteries can be serviced by the device - the main thing is that the cell case is solid. Users praise the implementation of the control panel. In general, the presence of a functional operator display is rare for chargers, but in this case, the introduction of the innovation was successful.
Negative reviews
Among the significant flaws, users highlight only the lack of support for the format of telephone batteries. Due to this drawback, the model, of course, cannot be considered fully universal, although it is possible to get out of this situation using special adapters. To minor flaws, users include a relatively low speed of updating results, periodic inaccuracies when measuring mAh, as well as overheating of the case. It should be noted that many consider the cooler as the weakest point of the Opus BT-C3100. The reviews, however, note that in the new versions of the device, the cooling system was significantly redesigned and improved. Another thing is that this did not affect the measurement errors for some indicators. The deviation range of 3-5% is still an unpleasant operational moment of this model.
How much is the Opus BT-C3100?
In the domestic market, the model is available for 1.8-2 thousand rubles. This is a relatively small amount, given the high-quality elemental base of the device and the functionality that is offered in it. If you wish, you can find a more affordable similar Chinese device with an extensive list of performance indicators, but such products will be significantly inferior both in measurement quality and in durability. If we compare the Opus BT-C3100 with analogues from the major brands Liitokala, La Crosse or Fujitsu, then its cost benefit will be negligible. Nevertheless, this product should first be compared with respect to its operational properties.
Conclusion
The device is unlikely to be useful to the average user of battery-powered equipment. Today, typical device models are optimally powered by simpler universal charges. The wide functionality of the Opus BT-C3100 in such cases can remain unclaimed. Such a purchase will justify itself, rather, in the hands of specialists or radio enthusiasts who actively use batteries of different formats. An important feature of the development from Opus is a wide range of parameters that the device captures when analyzing the filling of a serviced element. That is, in some ways, it is not so much a charger as a diagnostic device. This is evidenced by the external panel, rich in optional features and controls. The manufacturer thought over the balanced technical and operational qualities of the device, and its ergonomics, which are significantly improved in new versions.
