Custom Trucks, &
SUV Dual Battery Setups
For Custom Trucks, SUV's that do not have a need for
winching, off road lights, snow plows, you can still find a need for a
Hellroaring BIC. The backup battery system still provides
starting confidence for those unexpected events of draining your main
battery, including the common leaving your lights on
The backup system offers the ideal automatic operation
with protection even from alternator
failure. No, it doesn't replace an alternator.
But, when your alternator fails and you can't re-start due to a
drained main battery, the backup battery is there fully charged, ready
to start the truck and operate the vehicle for the additional time of
the backup battery capacity. In addition, this backup
configuration also provides extra starting power during cold weather
The Hellroaring Dual Battery, Backup Battery Setup
Now there is a better system! The Hellroaring Battery
Isolator / Combiner. The Hellroaring Battery Isolator/Combiner model BIC-95300B is essentially dedicated to the Backup battery setup. As a backup
battery system, it installs very easily. It will provide high charge rate
capability to both batteries.
When the main battery becomes discharged, just flip a micro-switch to
energize the backup battery and you can start
your gasoline engine. If your alternator had
failed, and you started your vehicle with jumper cables, your
engine would quit very soon after removing the jumper
cables!. Not so with the Hellroaring system.
You should typically have at least 2 hours of operating time with a 50
AH backup battery if you keep unnecessary accessories off. For
vehicles with a Diesel engine that requires two main start batteries, two BIC-95300B units
must be connected in parallel for backup starting along with two Backup batteries..
For this backup battery setup, the Backup battery must be Reserved all by itself with no loads connected. Therefore, all loads and accessories need to be connected to the main battery
system or other system batteries. Connect the Hellroaring Battery
Isolator/Combiner to the backup battery and your starter as shown in
Figure 1. And to simplify installation of the Remote
functions, we have available a Remote
Module kit as an accessory.
With this setup, you will have the security of a backup
battery fully capable of cranking your gasoline
engine even with a completely discharged main battery.
