ER5C (energy reach 5 cell) is a combination of C50R and C75. This was done because of production's need to move components and SNs back and forth between both projects and overall project similarities. If you look at the project area, you will see that some
of the traveler IDs end with -C50R or -C20. These are there for travelers that were different in their instruction and/or data collection and we wanted to distinguish that it was from the old C50R project. All of the C75 versions were just named ER5C with
no designation at the end.</div>

We are prepared to continue adding the designation to the end if C50 is done and the process is too different from the existing ER5C travelers that are intended to be used. We have also discussed with authors to add a radio button or checkbox in the first step
of the traveler to identify the style if there is no major difference in how the assembly is done. We discussed this with everyone before we made the combined project and all were in agreement of the efforts.</div>

I am concerned that ER5C is becoming a confusing term if it stands alone. We may rework a C50, build a C75, or (soon) a C60. How can the user quickly differentiate that they are pulling up the correct document?</div>
