Reduced Weight = More Horsepower
Physically speaking, shedding pounds means 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 ETX1200 is 6.9 pounds and is designed for 120-amp alternators or less with 1200 Peak Cranking Amps (PCA).
- The ETX900 is 4.9 pounds and designed for an 80-amp alternator or less with 840 Peak Cranking Amps (PCA).
- The ETX680/ETX680C or the ETX36 series is 3.9-4.1 pounds and is designed for 60-amp alternators or less with 680 Peak Cranking Amps (PCA).
If you have more than 120-amp alternator, you will have to put two of our lithium race car batteries in parallel to handle the current. Click here for tables and a more detailed explanation.

Testimonials
Dear EarthX, I want to thank you for great service. You warranted my battery, and exchanged it for a new one. I want you to know that I thought I was in for a fight, not used to such good service. Very well appreciated. Some times doing business online , especially second party , can be […] I have to admit that your customer service is well above the standard level that I’ve received from other aircraft businesses. I was expecting a “shrug of the shoulders” response regarding the limited two year warranty for a battery I purchased three years ago. What I was surprised to learn is that your company is […]
When I called a real person picked up the phone when I had an issue with my battery. I then emailed your Warranty folks and everything was taken care of right away. I got a call right back, followed up by an email, with a replacement battery in the mail! That’s Customer Service! I will […]
Thanks a million for the “care package”. It showed up this afternoon. The 36C was exactly what my 1190R needed, starter spins up like it should now – I should have bought this battery 3 years ago when I first got the bike. I appreciate your interest and help!

Dear EarthX,
I have made 10 or 15 engine starts since installing the new EarthX battery last week. It is PHENOMENAL! It spins the engine over much faster and makes the engine starts much better.
Gary W. (in an airshow performance plane)
Thank you so much for the quick reply. You folks have the service side of this business down pat. I can’t tell you how much it means to me to have been able to sort this problem out so quickly and painlessly. In my years in business I graded my […]
My Aprilia Futura 1000cc V-twin doesn’t like batteries recommended by the factory and when using them it struggles to start and usually kills them within 2 years. It also likes to leave me stranded costing $400 for tow trucks and the embarrassment comes free of charge. One of my co-workers is using your batteries […] OMG!!! You sold me a battery for my RV-8A at the Northwest Aviation Conference in Puyallup, WA. I put it in my plane a few weeks ago but the weather did not co-operate until today. What a difference! My starter does not whine anymore and it cranks way faster! Also, I still have not lost […]
Recently purchased and installed an ETX680C for my experimental plane. The 680C replaced a Ballistics Performance EVO2 battery. Your battery is FANTASTIC. There is an amazing difference in cranking performance–I can almost taxi my aircraft when just running the starter! Ted W.
Questioned myself for buying such a costly battery, however it has been one of my best decisions. This battery has performed exceptionally well and I will continue to upgrade to these Lithium batteries on all of my sport equipment!
Buck
The weight loss on my bike was felt immediately. Feels like a have a smaller bike now. Still can’t believe how light weight and strong starting ability. I’m thoroughly impressed. Hope it can hold out for the long run. Very happy so far. Install took a little TLC by bending some loop connectors but battery […]
By changing to this battery in my airplane, I shaved 10 lbs off the forward area and gave myself a far better battery. Easy fit too.
Don
Purchased the ETX900 for my 3300 Jabaru aircraft engine in my Zenith CH750. The new battery spins the engine significantly faster, allowing for starting the engine without preheating every time (anytime it was below 60 degrees F) What a difference it made and saved me just over 10 pounds. It’s worth the price.
Eric
After flying all weekend I must say I am impressed with this battery (ETX 900). My Odyssey PC 925 always worked well until recently with 4 years of use it started turning the prop a bit slower each time during start.
Your ETX 900 turned my engine and prop (IO-360, C/S) faster than I’ve ever seen […]
Greetings from St Louis,
>
> I just purchased and installed an ETX 900 in my Vans RV-4. I have an IO-360 engine with a constant speed prop so I need some good cranking amps. Due to weight and balance considerations the battery is mounted just behind the back seat in the baggage compartment. The previous […]Since receiving the EARTHX battery. . .moments before I left for a Mid-East Hare Scramble. . .I have climbed from 188th up to 38th overall finish.

Dear EarthX,
I purchased an ETX900 for an experimental aircraft. For 3 days I cranked on the motor and finally figured out I had a broken wire which stopped the engine from starting. The battery turned the engine over without hesitation and never needed charging. I was impressed with the performance of this light little battery!
After […]
Wow what a great customer service ! Your response was so fast and helpful.I always liked the performance and the quality of your battery, but now i really love your customer service ! Thank you so much i’m an happy customer !!!

EarthX, I’m speechless. Please let me know how I can sing your company’s praises most loudly. I can’t recall ever having such prompt and wonderful customer service!
I have been enormously pleased with the battery. It is light years more powerful than the lead acid OEM battery.
