All good day and pleasant education in technical issues of our blog. We have specially created a platform for live communication and exchange of experience in repair business, multicopter and other technical things. Tests of batteries and accumulators, practical experience of repair of various electronic devices and their batteries. The blog is closely connected with our laboratory and shop, all about what is written here, you can find and buy from us.
Pleasant viewing! Leave your feedback and share on social networks! We give discounts to the most active users:)
We have to admit that the study of this issue has disappointed us. After analyzing more than a hundred batteries for gyrometers lower and middle price segments, we do not our no specimens worthy of attention. In practice, it turned out that the presence of branded 18650 batteries in gyroscope batteries is rather an exception than a commonplace. So, how we are deceived.
Repair of gyro batteries always begins with an external battery assessment and measurement of voltages on the contacts. After that, the "patient" is opened and the insides of the battery are examined, the state of the balancing Board and interelement connections is evaluated.
The gyroscope is a relatively new vehicle, a special segment of two-wheeled electric transport. It has its own positive qualities and, of course, disadvantages. The two-wheel electric drive is powered by a built-in battery. As in other cases, it is a lithium-ion solution consisting of elements 18650. Gyrometer have a certain autonomy, in urban environments you can rely on a few kilometers, which is about 30 minutes of continuous driving.
Unfortunately battery screwdrivers not as durable as we wanted. The average life span is from one and a half to two years. Much depends on their operating conditions and charging mode. Very often it is necessary to face a fast discharge of the battery or its undercharging. Eventually there is a question of repair of the battery of the screwdriver.
