Lithium RACE CAR Battery

The RS-20 Lithium Car Battery has a built-in Battery Management System (BMS) to balance the Lithium cells for the safest, longest service-life possible. Additionally, this system has an automatic Low-Voltage Cut-Off that limits over-discharge and Protects the battery from damage.

With our exclusive “RE-START Technology” the RS-20 will go into a “sleep” mode with enough energy to allow you to “RE-START” your Race Car if you over-discharge the battery. This means if you accidentally leave your lights on or play your stereo until the battery shuts off, you can still start your vehicle and drive away… Simply press a button on the battery and RE-START your vehicle! No need for jumper cables, jump-starter or assistance – no other battery on the market offers that!

Additionally, the lithium battery cells used by the RS-20 are rated at 2000 cycles – nearly TWICE that of Lead/Acid!

RE-START Technology


The RS-20 Lithium-Ion Car Battery weighs only 10 lbs, puts out an incredible 1000 Amps, and can easily start a 900 Horsepower Big-Block V8! Yet it has a very compact footprint at L 9-1/2” x W 6.8” x H 7.5”.

Compared to a Lead/Acid Battery the RS-20 is roughly 70% Lighter in most applications. Designed for Race and Performance use, it can offer as much as an 80% weight reduction. This equates to roughly 25-40 lbs of instant weight-loss just by changing out the Battery! That makes it the most cost effective weight-loss product hands-down. To save this much weight in Carbon or Titanium parts would cost over $10,000 dollars. So enjoy better handling, shorter breaking distances, better acceleration and better gas mileage with the RS-20 Lithium Race Car Battery.


The massive weight reduction and ultra-powerful cranking performance of the RS-20 makes it perfect for use in Racing and Performance Vehicles. The RE-START function will provide a high level of comfort and satisfaction knowing you will be able to quickly start your vehicle with the press of a button in the event you drain the battery.

Other benefits include incredible vibration resistance, no liquids inside to spill, and no highly toxic materials such as Lead or Acid.

PLEASE NOTE: this battery is Only for use in RACE CARS and is Not intended for passenger vehicles. (New model coming soon for use in daily drivers and public roads!) Also note that the RS-20 is Not intended for deep discharge use such as powering stereos, or applications where very high Amp Hour capacities are required. It is intended to be used as a Starter Battery.
