  first each time, then this idea of using rechargeable 
  batteries would not be that much more convenient than

  do not have this effect, and it is even recommended that 
  only partial discharges be made before recharging them.

+ \subsection{Combining the Battery with the Motes}
+ 
+ 
+ Currently we are using 3.7V, 600mAh Li-Ion rechargeable batteries, manufactured by Ultralife Batteries, Inc.  Unlike normal rechargeable batteries that are found in electronic devices, these OEM batteries do not have connectors on them already, only two wires with positive and negative polarities.  What this means is that we also have to decide on the type of connector to use.  Judging from the amount of difficulty we have had with the Molex 51021-0200 crimp housings, it would be nice if some other sort of connector could be used, especially a larger one, since the battery wires are larger than the ones used to attach the battery case to the Molex power connector on the board.
+ (to be continued...)
+ 
+ Ideally, it would be nice if we could use the one connector for the entire mote.  This would leave us with three options: use the molex power connector, the adaptor jack, or a mini-USB jack.
