Why choose the NEW Rock Battery for your Lithium Solution?

Although the task of expanding the reputable Rock Racing Battery inventory has been rather heavy, the actual weight of the addition is the exact opposite- ULTRA LIGHT! A racer's ultimate dream of maximum power with minimal weight, we are proud to introduce the newest contender in the Rock Racing Battery lineup: the 16 Volt Lightweight Lithium Battery. At Rock Racing, we don't sell what we don't use. Our extensive vetting process of selecting a creditable manufacturer with verified data and substantiated success not only includes thoroughly reviewing the results of testing conducted by other racers, but also, our own. We can personally attest to the winning power of the 16V Lightweight Lithium Battery!  

IT HAS THE POWER TO WIN!

The Rock Battery Lithium 16V battery is incredibly powerful, recharges quickly, and weighs in at only 9 pounds! Yes, 9 pounds! With the lighter weight, the racer is able to reduce gross weight or move ballast where it will be most effective.

This is the ONLY lithium battery on the market based on prismatic technology. Prismatic cells are more durable and are able to store more power in a smaller area.

The Rock Battery Ultralight Lithium Battery is also internally balanced. This ensures that the battery discharges and charges its prismatic cells equally. Cell balancing on the battery increases the lifespan of the product dramatically. It is also an expensive option when building lithium batteries and that is why some (most) companies don’t do it.

The Rock Racing Lithium battery has undergone 7 years of research, development, and testing. One test that all automotive batteries are subjected to is the CCA (Cold Cranking Amps) Test. This is a Pass/Fail Test done to verify the CCA rating. To conduct a pass/fail test, they load the fully charged battery with half of its claimed CCA and crank ONCE for 15 seconds. The voltage must stay above 9.6 during the 15 seconds of cranking for the battery to pass. The Rock Battery Lithium Team did this same test with the new Rock Battery Lithium Prismatic cells, except they pulled FULL rated cranking for the 15 seconds. They waited one second and did it again. They repeated the 15 second cranking with 1 second pause 60 times before using the reserve power in the cell. The battery was slightly warm to the touch but it melted the shielding on the battery cables. Rock Battery Lithium’s Battery produced full rated and consistent power during the entire test and never slowed its cranking speed. Actually the cranking speed sped up as the battery temperature increased slightly.

We went one step further and did Real World Dyno Testing.  We don't just make bold claims...WE PROVE THEM!

Equipment Powered during test:

*MSD Digital Ignition with Grid Controller

*Race Pack/Data Logging Computer

*Delay Box

*Electric Fuel Pump

*Electric Fans

*Electric Water pump

After powering up all of the electronic equipment and running the MSD Ignition at a simulated 9500rpm we pulled the car in this state for a full 5 minutes.

*Starting Voltage - 16.9(balanced full charge)

*Ending Voltage After 5 Minute Pull - 14.8

*Recharge Time after Dyno Run - 25 Minutes

*Track testing with same car

*Starting Voltage - 16.9(balanced full charge)

*Ending Voltage After Run - 15.3

*Recharge Time after Run - 20 Minutes

To say the Rock Lithium battery passed these tests would be an understatement, It absolutely crushed them!

Frequently Asked Questions

*But is it safe? Don’t lithium batteries explode?

The Rock Lithium Battery is safe and was specifically designed for racing applications. To test, a Lithium cell is subjected to a puncture test in which a steel rod is driven through the cell. Rock Battery Lithium Cells passed this test without any explosion or fire. This can be an issue with other types of lithium batteries.

*How long does the Rock Battery Lithium battery last?

The life expectancy of the Rock Battery Lithium Battery is gauged by depth of discharge. Meaning, if a team used 90% of its reserve power it will last for 2000 charge cycles. In reality, when used in a race car running a 6al or HEI ignition, the depth of discharge will be under 50% resulting in a much longer life span. The average team can expect the Rock Battery Lithium Battery to last for approximately 10 years.

*Can I use my Rock Battery Lithium Battery with an alternator?

Yes. If you have a 16 volt alternator equipped vehicle this will pose no problems with our battery. Alternator output should be regulated @ 17.75 volts and 100 amps.

*Do I need to buy a special charger or can I use my existing battery charger?

While a standard battery charger could be used with some effectiveness, this most likely will damage the lithium cells. Using the Rock Battery Lithium Battery Charger is strongly recommended. It is designed specifically to charge the Lithium Prismatic Cells.

*Is there a Warranty?

Yes, All Rock Battery Lithium Batteries come with a Full 1 Year Replacement and Three year Prorated Warranty for any manufacture defects.*If damaged by user, discounted repairs/rebuilds for LIFE of product*
