OurDischarge Machine (Model EBC-B20H) is a professional-grade high-precision battery analyzer engineered for capacity testing and performance evaluation of 12–72V rechargeable battery packs. As an automatic battery discharge tester, it supports both constant-current discharge and automatic charging (with an external portable charger), enabling full-cycle testing of lithium-ion, lead-acid, and other battery chemistries.

The EBC-B20H offers exceptional precision: discharge current (0.10–20.00A, 0.01A step), discharge voltage (0.10–89.00V, 0.01V step), and cutoff voltage (8.00–88.00V, 0.01V step). Its rechargeable battery capacity tester function provides tiered accuracy: 0.001Ah for <10Ah packs, 0.01Ah for 10–100Ah packs, and 0.1Ah for >100Ah packs, ensuring reliable capacity measurement across a wide range of battery sizes.

Equipped with an LCD display for real-time monitoring of voltage, current, time, and capacity, the tester also connects to a PC via a USB-TTL cable for advanced functions—including test graph visualization, calibration, firmware upgrades, and automated test cycles. Whether you’re conducting R&D, quality control, or maintenance, our Discharge Machine delivers the accuracy, flexibility, and automation required for comprehensive battery testing.
