Sure Power multi-battery Isolators are designed for negative ground alternator systems, and batteries of the same nominal voltage. They electrically isolate main and auxiliary battery circuits so each battery charges and discharges independently. Sure Power Isolators can be used for a broad range of applications and are designed for marine as well as vehicle use. Special application isolators (including positive ground alternator systems) are available on special order.
For multi-battery applications as a solenoid priority system. Protects chassis charging system from excessive loading, allowing auxiliary batteries to be charged.
The battery seperator has two basic operational characteristics: Assist in engine starting and Protects the charging system.
