The FNIRSI HRM-10H measures a battery's internal resistance and voltage together using a true 4-wire, 1kHz AC method. It is the quickest way to match 18650 and LiFePO4 cells for a pack or to find a tired cell.
Sorting mode flags good and bad cells against your thresholds, and results are stored and exportable over USB. This is the HRM-10H kit; contact us to confirm the included probes and clips.
