+ === Connecting A Battery To TeleMini v2.0
+
+ There are two possible battery connections on TeleMini
+ v2.0. You can use either method; both feed through
+ the power switch terminals.
+
+ One battery connection is the standard Altus Metrum
+ white JST plug. This mates with single-cell Lithium
+ Polymer batteries sold by Altus Metrum.
+
+ The other is a pair of screw terminals marked 'Battery
+ +' and 'Battery -'. Connect a battery from 4 to 12
+ volts to these terminals, being careful to match polarity.
+
+ === Charging Lithium Batteries
+
+ Because TeleMini v2.0 allows for batteries other than
+ the standard Altus Metrum Lithium Polymer cells, it
+ cannot incorporate a battery charger
+ circuit. Therefore, when using a Litium Polymer cell,
+ you'll need an external charger. These are available
+ from Altus Metrum, or from Spark Fun.
