    Computerized Battery Analyzer with accessories

    The computerized Battery Analyzer is much more than a simple battery voltage tester or a battery load tester. It will test virtually any type or size of battery, any chemistry or number of cells, up to 55 volts. We are making this tester available with accessories intended for FIRST legal batteries, although teams may purchase the CBA without accessories and create their own cables for testing other battery types.

     

    The CBA not only tests the total amount of energy stored within a battery (capacity in amp-hours), but also graphically displays and charts the voltage versus time under a constant current load. Graphs may be displayed, saved and printed, and the axis parameters can be changed at any time. Multiple test graphs of the same battery, or multiple batteries, may be compared or overlaid; a very useful feature for teams looking to test capacity and performance of their batteries as they age.

     

    To run a test:

    • Install the CBA IV software
    • Connect the battery tester to your computer
    • Connect a fully charged battery to the battery tester
    • Click the "New Test File" Button 
      • If you wish to add an additional test to an existing file chose "Append Test" instead.
    • In the New Test window do the following.
      • Select "Discharge" on the left
      • In the blue box on the right click the "Detect" button
        • For an FRC Battery fill in the following settings: Lead Acid, 13.2V, 6 Cells
        • Enter the Ah of the battery 
          • Usually 18 for FRC batteries
      • Enter a name for the battery at the top under "Test Name:" and label the battery with this name for future comparison
      • In the center of the screen set "Cutoff V:" 
        • This is the voltage that the battery will be depleted to. 
        • For an FRC Battery we recommend 10.5
      • In the center of the screen set "Test Amps:"
        • This is the load that the tester will apply to the battery for the duration of the test.  
        • For an FRC Battery we recommend 7.5
          • This is the highest the tester can do on an FRC battery and will result in the fastest test. 
      • Click "Start" 
    • The test will now run for anywhere between a few minutes to a few hours 
      • Do not move or touch the battery at all during the test 
      • Pausing the test will result in a bad portion of data around the pause and is not recommended
    • When the test is complete a dialogue box will appear informing you of the result and the graph will be complete
      • Click "OK" and repeat the test for another battery. 

     

    The critical number to look for is amp hours (Ah) after the test. If the graph crosses the 10.5V at less than 12Ah after 2 consecutive tests from a fully charged state we recommend not using this battery in competition due to the increased risk of brownouts, especially near the end of a match. Such batteries should be marked and only used for things like practice, demos, or testing.

    Pigeon 2.0

    #am-3556a
    $355.00
    (2 In stock)

    Pigeon is an IMU with 9 degrees of freedom, containing a 3-axis magnetometer, accelerometer, and gyro. The gyro has built-in temperature compensation. Pigeon provides a heading by sensor fusing all 9 measurements. It can be connected to the Talon SRX for power and communication via UART, or it can be wired to the CAN bus while powered from a separate 12V source. Pigeon has built-in compass compensation for hard-iron, soft-iron, and physical tilt. The Pigeon 2.0 eliminates the need for on-boot calibration and temperature calibration and does not require stillness upon boot-up.
