In order for Delta-Q charger to deliver accurate charge voltage. Delta-Q IC series charger has a built in software settings which compensate for DC cable resistance. The default cable resistance compensation for IC Series charger is 20mOhm.
For setup with shorter/longer DC cable, the user may wish to further decrease/increase the cable resistance compensation to optimize charging .
The cable compensation resistance 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 10mOhm.
- The conductor from battery charger negative terminal to battery negative terminal is expected to have 10mOhm.
