This is a perfect example of marketing literature stretching the truth a little!

Yes, the CBA III can draw up to 40 Amps of current, but there is also a 100 watt limit. So, up to 40 Amps can be used for a test, but only if the battery being tested is less than 2.5 volts. (40 Amps at 2.5 volts = 100 watts)

For a robot battery (6 cells, 13.2 volts peak, 12.0 volts nominal), 7 Amps is the limit the CBA III will allow. (7 Amps at 13.2 volts = 92.4 watts). There are lots of safety controls in the software to avoid users setting up dangerous tests, and 7 amps is the maximum the software will allow for batteries of the voltage and capacity of our FRC robot batteries.
