RV Starting Battery Isolation
For motorhome types with high output alternators and large house loads while operating, consider the RV starting battery isolation technique as a simple solution to multiple use batteries. With this setup, a high output alternator can supply maximum charge current to large house battery banks. All batteries receive proper alternator voltage from an internally sensed alternator due to the very low ON resistance of the BIC-75150A (less than 0.008 ohms). Since there is no diode drop, the starting battery stays fully charged. Electrical loads on either battery will not draw from the other. If you choose this method, we recommend that you contact our technical support staff for assistance.
