  • Made in the USA. Why it matters:
    • Superior craftmanship; rigorously tested; high-quality parts.
  • Due to shipping regulations regarding shipping lithium batteries, the EarthX batteries have a hazmat fee when not shipped ground (We include this in the calculated shipping cost).
  • Extremely light weight, 70-80% lighter than lead acid batteries.
  • Very low self-discharge rate, it can hold a charge for the entire off-season (over six months) except in bikes with continuous draws such as a Harley.
  • Environmentally friendly, no hazardous lead or acid, non poisonous, non-toxic.
  • 4,000 charge cycle life versus 350 charge cycle life of a lead acid battery. Can last up to eight years!
  • Maintenance free.
  • Fast charging (as little as 30 minutes).
  • Higher voltage while cranking means faster starts.
  • Wide operating temperature range, will not freeze or boil-over.
  • Made in the USA with imported cells
  • Some applications may require the EarthX Terminal Adapter Kit (sold separately).

Product Description

Free Standard Shipping!

Order today and receive free standard shipping on your EarthX ETX18B High-Performance Powersports Lithium Battery. Only valid in the contiguous 48 states and not valid with any other offer.

Engineered and assembled in the U.S.A.

EarthX Lithium batteries, Lithium Iron Phosphate (LiFePO4), are designed to be a light-weight, maintenance free replacement of your standard lead-acid battery. These batteries will work with all vehicle charging systems and "modern" lead-acid battery chargers, thanks to the exclusive built-in electronics (Battery Management System, BMS). No other motorsport lithium battery offers built-in electronics which protect it from over-discharging or over-charging while keeping the cell's charge level balanced.

EarthX batteries are an exceptional value given the fact they can last four times longer than your conventional lead-acid battery, lasting up to 8 years. The battery includes a full 2 year warranty (not prorated like others). Your satisfaction is 100% guaranteed with EarthX's Factory Direct warranty!

What Makes EarthX Different?

  • Built-in circuitry (Battery Management System, BMS) to ensure the charge levels are equally balanced 100% of the time for optimal performance and life.
  • Built-in circuitry to protect from over-charging and over-discharging
  • No special cell balancing charger needed due to our built-in BMS.
  • Custom designed cells for maximum cranking amps, lightest on the market and up to an 8 year life span.
  • Cranking amps are rated using an American standard (SAE), not a Chinese standard so our CCA rating is equivalent to existing lead acid batteries.
  • Torture tested to extreme temperatures (-22F to 140F) and vibration (2G 25hz).

Powerful and compact!
July 13, 2022

I bought this battery for a Cafe racer motorcycle project and it has TONS of juice. It is able to easily crank my 900cc bike and still fit into the palm of my hand. As always I recommend checking your required CCA not just CA when looking for a battery. This battery also went dead from being used without an active stator (my fault) and I was able to easily recharge it with a 2 amp conventional battery charger. So far I am more than happy with this purchase and will recommend EarthX to anyone looking for a compact lithium ion battery that is safe and efficient.

Amazing battery!

These lithium ion batteries are truly amazing. Light weight and smaller. I had to use the spacing blocks provided.. my Yamaha vmax starter cranks faster and starts immediately even after sitting for extended periods. I installed lithium batteries in all three of my bikes and never had any issues.

I was using Ballistic Battery's in my 1974 kick only Harley sportsters that I converted to electric start, i wanted to keep the original battery boxes, with Ballistic I had mixed results, with the EarthX it spines the old iron head with little effort, I am a EarthX fan for sure

Product is great. It's light and compact and very powerful. Started my 1850 V-twin Roadliner up very easily. They give you spacer cushions if you are replacing a leaf acid battery. Would definitely but from Battery Mart again.
