Description
IBS-RBM Relay Booster Module
Optional upgrade for your IBS-DBS Dual Battery System (sold separately)
If your starter battery is deeply discharged the relay allows the engine to start from the auxiliary battery.
IBS systems without the booster module upgrade allow a manual link start when your battery is at 8.5 volts
The relay booster module upgrade allows you to start from a more deeply discharged battery – as low as 5 volts
Easy to install
