My son is in a Lego Mindstorms club in his middle school. They
placed 10th this year at the State FIRST competition in Illinois.
Anyways, the Bricks eat batteries like they are candy, and as the
batteries are draining the robots performance changes. Does anyone know
the best battery for this type of application ? What we'd like to see
is a battery that can supply a pretty constant current till a certain
point, then falls off quickly.
We've tried Alk's, rechargeable Alk's, standard, ... They all seem to
perform about the same.
Any suggestions of what to use or where there is a web site that shows
the different battery performance information (I've search around a bit,
but have not found any thing too useful).
