For many years of work, we have performed hundreds of tests and various types of measurements and tests of our products. The experience we have helps us build new prototypes of various types of batteries for various applications.

We are trying to develop and do not cease new measurements and tests so as to really know how our products work.

We check temperature of our batteries during tests when the battery is under current. We also check the temperature of connectors, cables and BMS during the discharge and charging process after the test to know that the battery is in perfect condition.

We must remember that the nominal capacity of the battery will be less than the real capacity by about 10%. It is caused by many factors such as decrease of cell capacity under load or leaving unused by BMS.
The example below shows a test of one of the serial built batteries for which cells with a lower discharge current and a larger capacity SAMSUNG 35E were used. The test is performed at an ambient temperature of 21 degrees Celsius.

The battery has a voltage of 36V and a capacity of 10Ah and is subjected to a discharge test under a constant load of 10A.

On the thermal imaging photos you can see the temperature of the battery itself during the discharge process, the temperature of the connectors, wires, fuse and BMS operation.

The discharge chart shows the whole process of how the voltage decreases over time until it is cut off by the BMS.

The example below shows the test of one of the series-built batteries for which high-current cells with higher discharge current and smaller capacity SAMSUNG 25R were used. The test is performed at an ambient temperature of 21 degrees Celsius.

The battery has a voltage of 48V and a capacity of 29Ah and is subjected to a discharge test at 20A constant load.
