Thank you to all who responded so quickly and thoroughly in the answers. We were in the middle of finalizing the design tonight and the students wanted to understand why the batteries can not be charged sitting on its side.

Our original design would have the batteries laying on its side with the top facing out when charging in the pit. At other places where space is not a constraint, we will lay the battery cart down on the back which is on wheels so all batteries will be upright.

Now at the pit, we can either lay it on the back and put it under the table or take the batteries out of the holder that carries two batteries and set it upright without the holder in the battery cart. Either way we are going to charge it upright. It may be hard for others to understand what I am talking about. We did manage to finish the CAD model tonight. We are going to tweak it a little, put in the details where the holes are to run the charger wires, power strips etc. We will post it here for you to see at a later date. It is really cool.
