Overview

West Mountain Radio CBA V--Computerized Battery Analyzers

West Mountain Radio CBA V--Computerized Battery Analyzers have advanced capabilities for scientific battery performance assessment.

* 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 V (previous model CBA II/CBA III were only 48 V max.); 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 maximum power output of a power supply or solar cell
* Optional 500 watt and 1,000 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 two 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)
* Extended Software Upgrade License unlocks features for serious battery testing
