EarthX scooter batteries are the most advanced Lithium batteries on the planet today, no one makes a more complete battery.  EarthX scoot batteries have a built in battery management system (BMS) that controls all aspects of battery operation.  This is the only way to ensure the long life and high performance that Lithium batteries are able to deliver.  Weighing in at 70% lighter than lead acid batteries they will also help improve the handling characteristics of your scooter.  Available for almost any scoot, see the cross reference chart below.  We have the best Price Match Guarantee and will beat any competitor's price, please inquire for more information.



Don't be fooled, no other Lithium batteries are as advanced as the EarthX batteries.  The leading Lithium battery manufacturer does not even include a BMS nor a smart charger with their systems.  They advise to use a normal lead acid charger which is the surest way to short life and early death of your advanced Lithium battery.  Other manufacturers include a smart charger, however this does nothing to maintain the battery during the vehicle's charge/discharge cycle.  ONLY EarthX batteries have a built in BMS to regulate the cells during every phase of the charge/discharge cycle.  This is the only method to ensure long life and peak power of your advanced battery.  Every single automotive Lithium battery has a built in BMS, why should your ATV battery be any different?

EarthX’s ETX Lithium scooter batteries are designed as a maintenance free drop-in replacement for the Original Equipment Manufacturers (OEMs) 12 volt lead-acid battery.  To ensure a seamless replacement process, ETX batteries are identical to or smaller than the OEM batteries.  The ETX lithium battery consists of 4 Lithium Iron Phosphate (LiFePO4) cells in series and one or more in parallel with integrated cell monitoring and balancing circuitry.

Lithium batteries are fundamentally different than lead-acid batteries.  A lithium battery voltage remains relatively constant while discharging, while voltage for a lead-acid battery decreases.   A lithium battery can use 100% of its storage capability (measured as Amp-Hour, Ah) while a lead-acid battery typically only uses 30%.  A 2Ah lithium battery has the equivalent capacity to a 6Ah lead-acid battery.  Lithium battery's cranking power will not drop-off and it will also crank your engine longer.  However when the lithium battery runs out of power, it does so abruptly.

The ETX Lithium battery’s integrated BMS continuously monitors each cell’s voltage.  If the voltage of a cell exceeds that of the others it will transfer charge from that cell to the others in the battery.  All lithium powered electronic devices on the market today have built in microprocessor battery management systems, and the microprocessor controlled charge transfer circuits in an EarthX battery can transfer higher levels of current than the typical BMS in today’s cell phones, laptops, or even the competitor’s motorsport batteries.  This ensures that the charge level of all cells remains equal, even with the high discharge (> 100Amps) and charge current (>10Amps) of your motorsport vehicle.

A cell can be permanently damaged if over charged (over-voltage) or over discharged (undervoltage) just one time.  In the case of over-charging (battery voltage > 16V or cell voltage > 4V), an individual cell can rupture and the entire battery will need to be replaced.  EarthX lithium cells together with the BMS create the safest motorsport battery on the market with more starting power and longer life.  The EarthX ETX Lithium Batteries have the following features:

• Flexible battery connection – EarthX batteries can be used in either left or right side polarity applications. You also have the option to connect the battery leads directly to your vehicle.
• Longer Storage Life - there is no need to float charge in the off season
• Environmentally Friendly - no hazardous chemicals and it can be recycled
• Fast Charge - can be fully charged in less than a half hour
• Maintenance Free!
• No Special mounting direction
• Will Not Freeze - Lithium batteries are dry cell technology and will not freeze
