What is Internal Resistance (IR) and how to test battery resistance

A battery can be regarded as an ideal voltage source in series with an impedance, which is called internal resistance. When the battery works, the voltage output is lower than the open-circuit voltage (abbreviated as OCV). The difference is the voltage drop caused by the internal resistance.  The internal resistance is measured by ohm (Ω). The […]

Update battery cell cycler software

One may encounter the problem that battery cell cycler software upgrade is needed, but there are still tests ongoing on the channels of the battery cell cyclers. The software could be updated without losing all the settings. After the update, the ongoing tests can be resumed. You don’t need to manually restart the battery cyclers
