Thanks Mike Bortfeldt that cable looks like it is exactly what I need.

We aren't actually planning on modifying the chargers that first provided. We are actually planning on making the charging station from scratch. So we will be purchasing a transformer, rectifier, voltmeter read out and designing and building intelligent charging circuitry. We plan on being able to attach 8 main batteries and a few of the small backup batteries to the charing station. We are also planning on adding in some built in power sources with terminal blocks so that we can run experiments and such off of them.

Our current charging setup is the car chargers with the app cables attached to them and the problem is that students will forget to plug them in or forget to rotate them which can leave us high and dry from time to time. So once we have a charging station that is able to handle all of the batteries at once we will always have our batteries well organized and fully charged. Not to mention that we will only have to have one AC plug coming out of the unit.

I will make sure to post pictures of the charging station once we are done with it. We might also post a parts list and schematic for how to make it.
