Hi, I am doing an experiment on energy usage of the turtlebot3 burger, using an INA219 current sensor connected to the battery. For this experiment, I require multiple repetitions of the same mission. To ensure the validity of the collected measurements, I would like to verify whether the turtlebot has any known effects on power provided from a fully charged battery versus one that has been used for a couple of runs already (and is thus partially discharged). This is to decide whether I should replace the battery before every run, or keep the same one for several runs that are executed after one another. Thanks!
