Physically speaking, shedding pounds is like adding more horsepower to your race vehicle. Weight reduction can be very expensive, but with EarthX lightweight race car batteries, you can reduce 80% of the weight instantly by switching out your heavy lead acid battery for a fraction of the cost.
To choose the right lithium race car battery for your application, you first need to consider the amount of current your alternator puts out. Once you know the max output of amperage that your alternator puts out, then you need to know how much cranking amps you need to turn the engine over. Match those factors up, and you’ll know which of our lightweight race car batteries to pick.
- The ETX1600 is 8.9 pounds. Max charge current rating is 160-amps. Delivers 1600 Peak Cranking Amps (PCA).
- The ETX1200 is 6.9 pounds. Max charge current rating is 120-amps. Delivers 1200 Peak Cranking Amps (PCA).
- The ETX900 is 4.9 pounds. Max charge current rating is 80-amps. Delivers 840 Peak Cranking Amps (PCA).
- The ETX680/ETX680C or the ETX36 series is 3.9-4.1 pounds. Max charge current is 60-amps. Delivers 680 Peak Cranking Amps (PCA).
Note: If your alternator rating is less than or equal to the max charge current of the battery, it is the right battery for your race car. Example: your alternator puts out 120 amps max current, then the ETX1200 would be your battery choice as it is designed to handle that amount of current.
If your alternator puts out 160 amps max current, then the ETX1600 would be your battery choice as it is designed to handle that amount of current.
Now what if you have a 180 amps max current alternator? You could put 2 ETX1200 batteries in parallel. Or you may be able to use the ETX1600 if your race car uses at least 20 amps to operate as this would drop the current to 160 amps, then it would be acceptable.
