  • 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.
  • 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 ETX12A 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).

What's the difference between the "equivalent" and "Actual" amp hour capacity?

The manufacturer includes the "equivalent" rating to show a more apples-to-apples comparison between the lithium chemistry and the lead-acid battery that you're likely replacing.

In performance and real life usability for lead acid starting batteries, they only use ~30% of the stated amp hours before the voltage drops so low you can not start your vehicle. Lithium batteries, however, have a 98% depth of discharge.

For example, the EarthX ETX36 is a replacement for a YTX20 battery, which has 18ah capacity. The amount of usable amp hours are [18ah x 0.3 = 5.4ah]. The ETX36 uses a 12.4ah lithium cell which is actually 7 amp hours more than the lead acid battery it's replacing.

The cranking power of this thing is on another level. Touch the start button and boom. Wow this battery is great. Worth every penny. Make sure to buy the side post conversion kit. It is a must for most motorcycles.

Awesome upgrade from the lead/acid battery in my motorcycle. Went from 70 cold crank amps to 135.

Lithium Bike Battery
October 15, 2018

Outstanding! Even with a brand new standard lead/acid battery this bike ( Yamaha WR450) always seems to crank a little slow and is hard to start, even after it is warm. With this new Li battery it cranks noticeably faster and fires up great even when cold! They are pricey being about twice the price of standard batteries, but since their projected lifetime is twice as long as a standard battery that helps offset the price difference. The super light weight of these batteries is also a real nice added benefit as well! They are a little smaller in size as well and I like the fact they come with several different sizes and thicknesses of sticky backed foam to help size them to nicely fit in the battery tray as well. TWO THUMBS UP!!
