EBC-B20H 12-72V Lithium Lead Acid Battery Capacity Tester — 20A, External Charger/Discharger Support, PC Software, Multiple Measurement Modes

For discharge testing, connect the battery pack to the tester’s "battery" connector using the clamp wire. For charging tests, in addition to connecting the battery pack, plug the charger's output into the tester’s "charger" interface and switch the charger on. The tester monitors the charge current and, when the measured current falls below the preset value, it treats the battery as full and turns charging off. (The tester does not regulate charging voltage or current; it only detects conditions and controls on/off switching.) Automatic charge/discharge sequences are supported with up to 5 configurable steps; each step may be set as a charging mode (requires an external charger) or a discharging mode, allowing fully automated multi-step tests. When connected to a computer, tests can be started via software and the unit will log and display voltage and current curves.
