A safe way to charge your auxiliary battery while driving
No need to tie to ignition, saves installation time
The isolator is automatic and is based on voltage, which saves installation time. When the entire battery system drops below 12.7 volts the solenoid opens and isolates the starter battery from the auxiliary battery.
The optional Switch allows for manual control linking the two batteries together with a push of a button. The isolator will manually operate allowing current to flow for 60 seconds without the alternator even if both batteries are below 12.7V.- Part # BATISOSW
The Battery Isolator monitors both battery voltages
Ability to use an external charging device to charge main battery through aux battery
Cost-effective protection against a flat start battery
