In order for the Delta-Q charger to deliver accurate charge voltage, Delta-Q IC series chargers have built-in software settings which compensate for DC cable resistance. The default cable-resistance compensation for IC Series charger is 20mOhm.
For a setup with a shorter/longer DC cable, the user may wish to further decrease/increase the cable-resistance compensation to optimize charging.
The cable-resistance compensation is calculated base on combined resistance of both the positive and negative conductors(round trip).
As an example: for 20mOhm cable resistance compensation.
- The conductor from battery charger positive terminal to battery positive terminal is expected to have 10mOhms of resistance.
- The conductor from battery charger negative terminal to battery negative terminal is expected to have 10mOhms of resistance.
