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.
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 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.
This is a 1.5" thick 45A durometer urethane wheel with a half inch hex bore. Great for accelerating game objects or for when low compression is desired. 4 inch outer diameter.
