The Storage Battery Systems SBS4815CT Battery Discharger and Capacity Tester is a fully programmable and portable constant current load bank with detailed data acquisition and display capabilities. This model features wireless battery monitoring technology. Compared with the traditional method of each module only monitoring 1 cell, the new wiring operation becomes easier because the quantity of new modules needed is only a quarter of old-fashioned modules. This model is available for offline and online discharging tests of multiple battery strings, and the SBS-4815CT can simultaneously record the actual discharge currents of each battery strings in the test. With automatic calculating function for the discharging current, SBS-4815CT installs the discharge current formula for all hour rates internally, so the setting interface can indicate the suitable discharge currents without manual calculation according to the marked capacities of battery strings and the testing hour rates. Display of the histogram of all batteries to follow the battery voltage tracks in entire discharging process, using the different colors to highlight the lowest and the highest voltage, which can simplify the analysis of the battery voltages.

The SBS-4815CT connects with a PC during the discharge for downloading of the real time data, which can also be downloaded via USB after the discharging process. The included powerful analysis software supports data downloading and analyzing through real time communication or USB memory devices. The software interface includes: battery voltages curve and bar chart, battery resistances bar chart, group voltage curve, current curve, capacities histogram, data form and so on. With a powerful capacity estimating function, the software can predict the capacity of each battery in the tested group. The software shows the data in different formats, including bar charts, curve, and form. Any window can be magnified, and the software automatically generates EXCEL data reports make it convenient to send or download data.
