When temperatures reach
below 0 degrees F, the cranking power loss
in the battery becomes significant. At the same time, the
cranking load from the engine becomes significantly
greater. As temperature drops further, a point is reached
where even a fully charged battery will
not supply enough power to
crank your engine. This problem is sometimes overcome by
using an overnight engine block heater. But, sometimes you
don't have access to the electrical power for the heater such as when
in a parking lot or when you are in the field hunting.
In the Rocky Mountains,
for example, you could be in a hunting camp when a storm comes through,
dropping the temperature by 50 degrees F. This can be a
dangerous situation if you can't crank your engine! If you
live in a cold climate and spend time in remote outdoors, or don't
always have access to heater power, then you need the added security of
the Hellroaring BIC-95300B and a dual battery
Backup battery setup. When the Hellroaring Battery Isolator/Combiner
remote switch is ON, the Backup battery supplies additional power to
crank the engine.
Warm Weather Backup Start
When you are camping, sometimes you
leave your trailer in the campground and head for your favorite fishing
spot in a remote area. You arrive at your spot and fish
until dusk. Upon returning to your vehicle, you discover
your vehicle won't crank. You hadn't noticed that your
alternator had quit working yesterday. So all that time
driving around you were draining your battery. Now you are
in a pickle.
You could have prepared for this
situation by installing a Backup battery in your vehicle
(remember, you no longer have your trailer battery with you).
By installing a Hellroaring BIC-95300B, your backup
battery would be fully charged.
This gives you options
without help from the outside world.
If you hooked
up the standard remote switch feature, you can switch ON the Backup battery to your system and be able to
crank your gasoline engine (and drive for about 2
hours with no lights or accessories on).
If your remote
switch feature is not hooked up, you could open your hood and connect a
small, short jumper wire from the "remote switch" terminal to the
"Backup battery" terminal on the BIC unit. Proceed
as in option 1 above.
If the above
options fail to crank your engine, then it is very likely you may have
a problem other than your battery. Anyway, as a last
resort, you can swap batteries (assuming you also have the tools you
you want the convenience of being able to fully crank
your gasoline engine with a backup battery, we recommend using a
BIC-95300B configured for high current with heavy gauge (one 2 or 4 AWG wire
from the starter solenoid (or main battery +) to the BIC, and one 2 or 4 AWG wire from the BIC to the
backup battery with a 150A fuse at one or both ends), and with a Remote Module. Diesel Engines that require two main start batteries would require 2 BIC-95300B units wired in
parallel and two Backup batteries for Backup starting.
With the Hellroaring BIC-95300B and an backup battery, you will soon
be on your way and a "hell
of a situation" avoided.
