* Improvement/Enhancement on CBA V


Scientifically Analyze Battery Performance

  • True constant current battery capacity test with results graphically displayed, constant power testing supported with Extended software upgrade
  • Discharge current is software and electronically regulated using a solid state switch and fan cooled electronic load
  • Test any type of battery; coin cell to automotive or larger. Presets for NiCad, NiMH, Lead Acid, Li Ion, Li Poly, Alkaline, Carbon Zinc, Mercury etc.
  • Solar cell profiling capability
  • Lower current testing capabilities - down to 10 mA
  • Multiple discharge tests can use Watts as a parameter (CBA II/CBA III only allows current)

Perform Fast, High Power Testing

  • Tests quickly at real world load conditions, up to 150 watts or 40 amps maximum, whichever is  higher
  • High voltage testing at up to 55 volts (CBA II/CBA III is only 48V); the equivalent of 1 to 38 NiCad or NiMh cells
  • Perform power profile test (increase current at user's rate to see how voltage/power responds), useful for testing max power output of a power supply or solar cell
  • Optional 500 watt and 1000 watt amplifiers

Accuracy and Precision for Demanding Applications

  • Remote voltage sensing for higher testing accuracy *
  • On-board computer performs accurate measurement with 12 bit effective resolution. Auto ranging for 2 current ranges and three voltages
  • Each CBA is individually calibrated with a computerized calibration system
  • Calibration certification data provided with CBA V Pro
  • SDK for developing your own scripts or programming
  • TTL UART port that can be controlled by an Arduino, Raspberry PI, or other embedded system with a TTL serial port

Built-in Safety Features Provide Superior Battery Protection

  • Improved cooling system allowing higher continuous loads for testing *
  • Additional LED status indications *
  • Fuse blown LED and easy to change fuses *
  • Fail safe: automatic protection of temperature, current and power
  • Safety watchdog stops a discharge in the event of a computer crash
  • Discharge test current user selectable from 0 to 40 Amps
  • Timed discharge test (stop discharge once certain Ah has been reached)
  • Dynamic test (alter test current using panel on the side of the software, without having to stop and start a new test)
  • Automatic voltage shut off at end of test using a software recommended or user selected safe discharge voltage
  • Automatic over-temperature shut off at end of test at using a software recommended or user selected maximum temperature with optional external magnetic temperature sensor

Free Standard Software for Data Analysis

  • User selected battery cell chemistry, number of cells and test current
  • Software recommends safe tests based on user supplied battery information
  • Automatic graph setup and scaling
  • Measures and displays voltage, current, amp-hrs, and watts
  • User can set the criteria for "Easy-Go/No-Go" testing
  • Easy overlay comparisons of multiple graphs may be displayed saved and recalled
  • Save, display and print battery test graphs and battery labels
  • Plug and Play high speed USB interface, with easy to use and intuitive Windows® software        supplied on CD ROM
  • Manage individual tests on any number of CBA V units connected to the same PC
  • Software has no limit on number of CBA Vs that can be attached (CBA II/CBA III required multiple unit license)
