 ==== adjust charging setpoints ====
+If your sag is consistent you could adjust your setpoints upwards.  If you have 0.2v sag and want 14.0v you would configure the setpoint to 14.2v.
+Or if your battery manufacturer offers a range of charging voltages like 14.0v - 14.4v you could configure 14.4v and know it will be ≤14.4v in real conditions.

 ==== calibration ====
+The controller may also have a **voltage calibration** setpoint.  If your sag is consistently -0.2v you could input that calibration.  You put in 14.0v or whatever you want and the controller increases voltage by 0.2v.
+Unfortunately, sag varies with current so the user might need to figure out average sag in their use case.
