Research in any field requires narrowing down all variables to only a select few. In electrically assisted manufacturing research, there is often significant variability in the output of DC power supplies, which has been overlooked in the past. In order to control this variable, we have created our own battery bank, which will output a clean signal. A switchboard has been incorporated to allow for any configuration of the four batteries to be used. The drawings and parts used to create this battery bank can be found below.
