Eight-channel 23 V / 50 A storage battery tester with independent channel control, high-accuracy CC/CV charging, constant current discharge, and up to 1000 W discharge per channel. Ideal for 2–20 V lead-acid and similar systems requiring precise capacity, performance and float-charge evaluation, with TCP/IP PC connectivity, Excel reporting, and full protection (reverse, OVP, OTP, short-circuit, power-down).
The Semco SI BCDS 23V 50A 8CH is a robust storage battery charge–discharge tester designed for high-current 2–20 V packs. Operating from AC 220 V ±10%, 50/60 Hz, it provides 8 fully independent channels, each supporting up to 690 W charge and 1000 W discharge (resistive heating). This makes it suitable for demanding capacity, performance and life tests in labs and production environments.
The system offers 7.3–23 V adjustable constant-voltage charging with ±0.03 V tolerance and 2–20 V adjustable discharge cut-off, also with ±0.03 V accuracy. Charge current is programmable from 0.5–30 A, and discharge from 0.5–50 A, both in 0.1 A steps with ±0.03 A tolerance. A 4-core wire sampling method ensures stable voltage and current measurement. Each channel can run up to 90 hours per step and handle single-test capacities up to 999 Ah, with 1–16 cycle index and configurable recording by time, voltage and current intervals.

The tester supports constant current & constant voltage charge and constant current discharge, with cut-off by voltage, current, time and capacity. A built-in float charge conversion automatically switches to trickle mode after 3.5 hours at high constant voltage or when current drops to 0.3 A, enhancing battery life and safety. Comprehensive protections include power-down memory, reverse connection, over-temperature, over-voltage and short-circuit, plus AC 1000 V/2 min inter-channel insulation.
Designed for 0–40 °C, ≤70% RH operation, the compact 900 × 350 × 180 mm chassis uses clip-type fixtures to connect 8 batteries simultaneously. With TCP/IP host communication, LAN port, Windows-based software and Excel report export, the Semco SI BCDS 23V 50A 8CH is a practical high-power platform for accurate testing, QA and characterization of industrial storage batteries.
Semco SI BCDS 23V 50A 8CH , a high-precision Storage Battery Charge Discharge Tester designed for efficient testing and performance evaluation of battery cells. This advanced system supports 8 channels, allowing simultaneous testing of multiple batteries with high accuracy.
