Historic Size of Battery

[Ed Law]

Thanks Cory, Al, Don and Jim,

We will modify our design slightly to charge the batteries in upright position.

We will leave half an inch in each direction to accomodate slightly bigger batteries in the future and swelling during charging.

We will put inserts to take up the slack and change them to different sizes to accomodate batteries of different sizes in the future. I like the idea of using light weight slippery plastics. What will be a good way to secure these inserts that is removable?

We are going to CAD it tonight and build it during Christmas holidays.

The loopy side of velcro should do the trick, and it's soft enough that if a battery needs to be inserted without any plastic spacers, it would just slide past.

Alternately, depending on how its built, the spacers between batteries themselves can be adjusted. I'm looking for a picture of my team's station to tell you what I mean...

Don't forget that the batteries need space on all sides for cooling during charging, If you leave .1/2 inch, ensure that there enough airflow.

I participated in a similar project a few years ago. In the process we took photos to benchmark what other teams were doing. Those photos are available at http://picasaweb.google.com/Mark.Kra...tBenchmarking# for anyone doing a similar project.
