Quick Overview:

Battery Discharger / Capacity Tester for 20–60 Vdc Battery Systems

The SBS-4815CT is a fully programmable and portable constant current load bank including individual cell monitoring wireless modules with detailed data acquisition, display and reporting capabilities.

Built-in memory continuously records discharge data including: overall system voltage, current and individual cell voltages (when modules are installed).

Parallel Operation

Alone the SBS-4815CT has a 0–150 Amp constant current draw range. However it is possible to parallel additional load banks of the same voltage range with the SBS-4815CT to increase current draw.

With the optional P/N 8400-600A DC clamp the user can discharge up to 750 Amps and the SBS-4815CT will monitor the total DC current being drawn by up to three load banks in parallel.


  • Can be powered from DC or AC power supply
  • Weighs only 21 lb.; designed for portability
  • Can be slaved with other load banks of the same voltage to increase discharge current


  • Voltage and current range: 20–60 Vdc / 0–150 Amps
  • 5.7'' LCD touch screen
  • 4 adjustable stop points and multiple alarm designs to control the process intelligently
  • Wireless modules that measure and record individual cell voltages during testing
  • View test data in real time on screen or with computer via RS232
  • Download data after discharge to USB drive
  • Computer software for capacity evaluation and report generation

Analytical Software and Internal Memory

  • Powerful analytical software calculates test results and reports cell/battery conditions and capacity
  • Software interface displays detailed graphs and charts
  • Ability to export raw data into customized Excel reports
  • Automatically protects and saves data from an unexpected test stop/end
  • Menu interface provides data management operations for parameter settings, test results review, and download by RS232 or USB device to the computer software

Wireless Modules

  • Included for collection of cell voltage data during testing
  • Advanced technology that wirelessly communicates readings between modules and load bank
  • For 2/6/12V batteries
  • One module supports voltage measurements for up to 4 cells
  • Easily locate failed cells in battery and estimate actual capacity of each cell
