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

The EBC-B20H is a 12-72V capacity tester designed for lithium and lead-acid battery packs with external charger/discharger support up to 20A and PC software control. For discharge testing, attach the battery pack to the tester’s "battery" connector using the clamp wire. For a charging test, connect the battery pack as above and also plug the charger’s output into the tester’s "charger" interface, then turn the charger on to begin. The unit monitors charging current and, when the measured current falls below the preset threshold, treats the battery as fully charged and switches charging off. Note: the tester does not regulate charging voltage or current; it only detects conditions and performs on/off control. Automatic sequences are supported — you can program up to 5 steps, each step selectable as a charging (requires an external charger) or discharging stage, allowing multi-step charge/discharge cycles to run without manual intervention. When connected to a computer, tests can be started via software and the tester will log and display voltage and current curves for analysis.
