You've found it. This is (in our humble opinion) the holy grail of batteries.

Why? Well, it's the only lithium battery contender with a fully integrated onboard battery management system. Sound like marketing mumbo-jumbo? It's not. 

Brass tacks differentiators:

  • It will protect itself from over-discharging.
  • It will protect itself from over-charging.
  • Due to the built-in management system, you can use a cheap/generic charger, rather than forking up for a specialty li-ion charger. 
  • EarthX makes these bad boys in Colorado, which we think is pretty cool (as opposed to shipping them from overseas).
  • EarthX backs these up with a full value 2-year warranty, which is music to anyone's ears who has ever dealt with a "lemon" lithium battery. 

If you're on one of the larger adventure bikes and tend to run a bunch of electronics/heated gear through winter weather, you may want to consider upgrading from the ETX24C to the "Ultra Cranking" ETX36C for some extra cold season oomph. 

Here's what EarthX has to say about them:

Exclusive Features:
–Over-discharge protection (#1 killer of all batteries and other brands do not protect against this and void the warranty)

–Overcharge protection (Other brands do not protect against this and void the warranty)

–Built-in cell balancing technology (Other brands must use a special balancing charger in order to level the charge of each cell. Your vehicle is what charges the battery most of the time if you do not have built-in cell balancing technology, how is your battery balanced while using it?)

– Short circuit protection up to 1,000 amps (Other brands void the warranty if you short the battery)

–Excessive cranking protection (Lithium technology is different than a lead acid battery and needs to be protected from heat)

–2-year full coverage warranty (Not a prorated warranty that offers you the replacement at a discounted rate if they don’t void the warranty)

–Unique and exclusive design (Custom design with the terminals down the center and most models come with reliable brass terminal adapters for straightforward installation)

– Designed, engineered and assembled in the USA

Why choose an EarthX lithium battery? S P E E D
S= SPEEDY CHARGING- EarthX ETX batteries will charge 2-3X faster than a lead-acid battery.

P= POWERFUL and LONG LASTING- EarthX ETX batteries crank your engine over easily and will improve your starting performance as their nominal voltage is 13.3V compared to a lead acid which is only 12.6V. Also, EarthX ETX batteries life span is much longer than a lead-acid battery and can last years longer!

E= EXTREMELY LIGHTWEIGHT- EarthX ETX batteries are up to 80 percent lighter than their lead acid equivalents. Lighter weight = better performance! This saves an average of 2-3 lbs. for dirt bikes, 6-8 lbs. for street bikes and 10-20 lbs. for touring and cruiser bikes.

E= ENVIRONMENTALLY FRIENDLY- EarthX ETX batteries are environmentally and user-friendly. Nonhazardous, nontoxic, nonpoisonous. Will, not sulfate, will not corrode, will not freeze, will not boil over, will never need water added and will not spill acid EVER!

D= DISCHARGE RATE- EarthX ETX batteries have a much slower discharge rate than lead-acid, and the need to charge them is greatly reduced.

    Lithium battery

    Old battery lagged when the bike was cold. Not this one. Works like a champ. And KTM Twins got it to me fast!

    Dead battery

    1 volt showing. Would not charge using correct charger. EarthX was good about the warranty. Shipped new one right out.

    Earthx battery in KTM 1090 is not the same as stock

    The center mounted terminals on the battery make it extremely difficult to mount this battery using the stock bolts and wires. It was a big letdown for me to have to remove the rubber battery tray cuz it just wouldn't fit. it also required flexing the big and thick heavy battery wires in a way that was very difficult and I don't believe will be good for the wires or the battery terminals.

    Strong and Tough

    Great product. Easy to fit the 1190 Adventure R with supplied foam spacers. Impressive cranking power. The battery survived a 100km/h crash that destroyed the bike.
