EBCA40L Battery Capacity Tester 40A 200W Electronic Load for Accurate Programmable Charge Discharge

EBCA40L Battery Capacity Tester Overview A precision bench tester designed for measuring and validating battery capacity and performance for cells and small battery packs with voltages up to 5V. Offers programmable discharge and charge modes, current capability, and accurate capacity measurement for laboratory, workshop, and production use. Key benefits Accurate capacity and current measurement to verify battery performance and detect weak cells. Current accuracy is 0.2 percent plus 0.01A for reliable results. Flexible discharge and charge control for repeatable testing: supports constant current discharge and constant power discharge, plus constant current and constant voltage charging. Wide current range and strong power handling: 0.1 to 40A and up to 200W discharge power to cover a broad set of cells and small packs. Clear termination options: stop tests by time, lowvoltage threshold, or manual control to match test requirements. Active cooling for stable performance during extended tests. Technical highlights Input voltage: 110V and 220V Maximum discharge power: 200W Voltage measurement range: 0 to 5V Current range: 0.1 to 40A Current accuracy: 0.2 percent plus 0.01A Discharge modes: CC constant current discharge and CP constant power discharge Discharge termination: by elapsed time, voltage falling below a preset lower limit, or manual stop Charging mode: CV constant current and constant voltage charging Charging termination: when charging current drops below a preset lower limit or by manual stop Cooling method: active fan cooling Capacity measurement resolution Up to 10Ah: resolution 0.001Ah 10Ah to 100Ah: resolution 0.01Ah Above 100Ah: resolution 0.1Ah Included accessories One online cable One pair of test cables One power cable Practical applications Cell and pack testing in service and shops for singlecell Liion, LiFePO4, NiMH cells, and USB power banks that operate below 5V. Quality control and production sampling for power bank manufacturers and component suppliers requiring repeatable discharge and charge cycles. Educational labs and R and D benches where accurate capacity, current, and controlled charging and discharging are needed for experiments and verification. Additional notes Picture is for reference only. Battery is not included. Device supports precise, repeatable testing through programmable discharge and charging profiles, with active cooling to maintain performance during longer cycles. This tester is intended for users who need reliable capacity measurement and controlled charge and discharge for batteries and small packs operating within the 0 to 5V range, combined with flexible termination options and current capability.
