SMART DUAL BATTERY ISOLATOR

The Sea-Dog Smart Dual battery Isolator allows two batteries to automatically charge at the same time and then isolates the batteries, ensuring the starting battery is always charged and ready for use. It automatically engages or disengages the circuit at pre-set voltages, eliminating the possibility of discharging the primary starting battery. It features an LED indicator to alert the user when the unit is engaged. This unit is made of machined brass with a weatherproof injection molded nylon housing and silver tipped contacts.
