Cold Weather Starting Boost

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-75150 or BIC-75300 and a dual battery setup.   When the Hellroaring Battery Isolator/Combiner remote switch is ON, the auxiliary battery supplies additional power to crank the engine.  

 

Warm weather Starting Boost

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 an auxiliary or backup battery in your vehicle (remember, you no longer have your trailer battery with you).    By installing a Hellroaring BIC-75150 or BIC-75300, your auxiliary or backup battery would be fully charged.    This gives you options without help from the outside world.

1)

 

If you hooked up the standard remote switch feature, you could switch it ON, allowing some charge to transfer from the auxiliary to the main battery.    After about 15 minutes (with the BIC-75150) or immediately with the BIC-75300 (configured for high current), you should be able to crank your gasoline engine (and drive for about 2 hours with no lights or accessories on).
2) 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 "Auxiliary battery" terminal on the BIC unit.    Proceed as in option 1 above.
3) If your vehicle still won't crank (with the BIC-75150), you could use a pair of jumper cables to to further increase your cranking power available to the starter.    Because both batteries should already be grounded with short heavy cable, you only need to jumper the positive side. You can lower the resistance by using both halves of the jumper cable in parallel (+ to +).
4) 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 need).
If you want the convenience of being able to fully crank your gasoline engine with a backup battery, we recommend using a BIC-75300 configured for high current with heavy gauge (one 2 AWG wire from the starter to BIC, and one or two 4 AWG from the BIC to the backup battery)   for up to 300 Amps cranking and 480 amps initial peak current capability.  Diesel Engines require 2 units in parallel for up to 600 amps cranking and 960 amps initial peak current.

With the Hellroaring BIC-75300 and an backup battery, you will soon be on your way and a "hell of a situation" avoided.
