But for long time battery tests, such as for battery life-cycle tests, this kind of tests usually will last for weeks or even months. In this situation, the result file will become too huge for computer to handle. In another word, it takes you about months to get the testing result, but in the end you even can't open the result data. That's disaster, right?
So, when you are trying to start up a life-cycle test or other similar long-time battery tests, please remember to modify the default sampling interval from 0.1s to 10s or even 1 minute for the best result.
