you install a high power audio system in an automobile, pickup, 4x4, or van, you need the
security of backup starting power for your vehicle or at least isolation from your
starting battery. Locating a suitable space where you can put the additional
battery and isolation device is just one of the issues you will face. Your
typical Battery and Isolator can take up substantial space. Some battery
manufacturers have developed small starting batteries with enough short term power to
start your vehicle after you drained your main battery while thumping your tunes.
But, you will still need a lot of space for your isolator and switching
system for emergency starting. That is....until
our Hellroaring BIC's came along!
With a Hellroaring
BIC-95300B, you can have automatic charging and isolation of your backup
battery. You will also be able to quickly energize your backup battery for
starting. Our BIC-95300B keeps the backup battery charged and
ready to start your vehicle. Yet, it is packaged in a relatively
For a simple installation, we suggest you use your combination deep cycle/starting
battery for all your primary vehicle operation and audio amps. This way, your
alternator and main battery can be connected directly to your amps to achieve the most power transfer
possible. This also simplifies the installation and use
of a backup battery. The operation of the Hellroaring BIC-95300B is
simple. It automatically combines your backup battery to your
charge system only when it is charging. It automatically disconnects your
backup battery from your system when there is no charge voltage, thereby retaining the charge in the Backup battery. When you need
backup starting power, simply energize the BIC-95300B by changing positions on a small
signal switch or with our Remote Module.
With a little extra re-wiring, you could use our lower cost BIC-95150B to simply isolate your
starting battery, using the Start side isolation method, and run your alternator output directly to your heavy loads and deep
cycle battery system. Either way, you should be able to use as large an
alternator as is available because most of the alternator current will not go through the
For Audio systems under 500 Watts, the basic Auxiliary battery isolation method of
our BIC-95150B works well and is very simple to install.
