The Smart Battery Tester measures and analyze a single lithium, Li-ion, or LiFePO₄ battery cell — 18650, 21700, and 26650.

The accuracy of the internal resistance and battery capacity are ±1 mΩ and ±0.3%, respectively. It also measures current, voltage, and temperature of the battery cell. The user can export the measurements in CSV format file, and monitor the parameters through LCD or mobile application (based on IoT).
