 # LipoCharger
 
-This is a simple but effective charger for LiPo batteries.  It has a higher
-charge rate than the on-board charger on [TeleMetrum](../TeleMetrum), and
-will be necessary for charging the batteries used with projects like
-[TeleNano](../TeleNano) and [TeleMini](../TeleMini), which do not have 
-on-board charging capability.
+This is a simple but effective, dual-rate, standalone charger for Lithium
+Polymer batteries.  It supports who different charge rates, approximately 
+100mA and 500mA.  The higher rate is good for batteries of 400 mAh and higher
+including the 900mAh cells sold with [TeleMetrum](../TeleMetrum) starter kits,
+while the lower rate is more appropriate for the 110mAh cells often used with
+[TeleMini](../TeleMini).  A standalone charger is essential for use with
+TeleMini since it does not have on-board charging capability.

 ## Future Plans ##
 
-We need to build and evaluate some prototypes, and review costing, before 
-deciding whether this design will go into production.
+After some iteration, we have settled on a design that meets our needs.  
+Boards will be available for sale soon.
