| 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. |

Example: The absorption setpoint (Vabs) is 14.0. The sensed battery voltage is only 13.8v, so the controller actually puts out 14.2v.((or whatever it takes to get 14.0v at the battery)) | Example: The absorption setpoint (Vabs) is 14.0.
