+Different battery types have different charging requirements:
+  * lithium - no minimum, charge at any rate up to the max
+  * flooded lead-acid:  minimum [[electrical:12v:battery_capacity|C]]/10 (10A per 100ah of capacity)
+    * minimum ratio with MPPT = 1.25w:1ah
+    * minimum ratio with MPPT = 1.5w:1ah((1.44w:1ah, actually))
+  * AGM lead-acid:  minimum [[electrical:12v:battery_capacity|C]]/5 (20A per 100ah of capacity)
+    * minimum ratio with MPPT = 2.5w:1ah
+    * minimum ratio with MPPT = 3w:1ah((2.88w:1Ah))
