IBS-DBR Configurations

Car/4WD with manual Link

Simple installation in a SUV, car or 4WD. Link function allows to perform full link start from aux battery. Aux battery can also be a removable temporarily used battery.

Car/4WD with manual Link

Triple battery in 4WD with combined Link

Triple battery to extend battery capacity. In emergencies all 3 batteries are linked with the manual link function from the IBS-DBS or DBi-DBS. Energy level can easily be displayed with the IBS-SBS (battery display).

Each battery supplies its range of appliances. All batteries are charged simultaneously from alternator. If Solar is installed charge is distributed onto all 3 batteries automatically. Solar will have priority on battery where it is installed, normally AUX1.

Triple battery in 4WD with combined Link

Dual battery 4WD with trailer, combined Link

Very useful for all customers using trailers. Trailer battery is  charged while driving. IBS-DBR detects if trailer battery is not present IBS-DBR disengages safely the charge to the power plug, no misuse is possible. If solar is installed to trailer and enough charge is available, charge is distributed to Main and AUX battery in the car.

In emergencies the link function from the IBS-DBS links all three batteries for a safe start. Use adequate wiring to the trailer.

IBS-DBR installation is also possible if other than IBS Dual Battery System is installed.
