LITHIUM-ION BATTERIES CANNOT BE SHIPPED INTERNATIONALLY BY WILD STEED WORX.
DO NOT USE A LITHIUM-ION BATTERY IN ANY BIKE WITH A HORSESHOE TYPE OIL TANK THAT SURROUNDS THE BATTERY.
EXCESSIVE HEAT WILL KILL THE BATTERY.
DO NOT USE A LITHIUM-ION BATTERY IN SUB 40 DEGREE WHEATHER.
IT CAN CAUSE THE BATTERY TO SELF DESTRUCT UNLESS THERE IS A WARMING BLANKET AROUND THE BATTERY.

Beware competitor batteries. They might be cheaper but they likely have lower amp hour ratings which your beast of a Big Dog will eat for lunch. WSW and our customers have had the best success with Anitgravity's batteries and specifically the two models, ATX-20-HD and the YTX-12-24, we sell.

The Antigravity ATX20-HD battery is a High Power, lightweight lithium replacement for the popular YTX-20 size Lead/Acid battery. This is our HEAVY DUTY version, designed with significant Power and Amp-Hour Capacity in this popular case size.

• YTX20 Standardized Case Size: 6.89 x 3.4 x 5.12 inches (LxWxH)
• 780 Cranking Amps (Ignore the AG website indicating 900 CCA it is not correct)
• 30 Amp Hours (PbEq), 15Ah (Actual)
• 5.18 lbs
• Lighted Voltage Indicator to see state of charge (doesn’t have RE-START)
• Safest Battery Technology using full BMS and Lifepo4 Lithium chemistry
• Compatible with 10 OEM battery sizes (see below)
• Can be mounted in any orientation

ATX20-HD

HEAVY DUTY Series

OEM Size Lithium Battery (Direct Replacement)

The Heavy Duty ATX20 does not have our RE-START built-in jump-starting feature but offers a deeper level of Discharge for more usable Capacity and more Power for Cranking. The ATX-20-HD also has a FULL Battery Management System (BMS) to better protect the battery from over-discharge and over-charge as well as having Thermal Protections. This makes for the safest and longest life-cycle possible.

Many Applications

These batteries are intended for those special applications where an extremely compact size with the most Amp Hours possible is required. We have focused these Batteries to work in Performance Street/Race Motorcycles, Powersports and Automotive Vehicles*; Large Touring Bikes that want extra Capacity; and other uses such as Experimental Aircraft. They can even be used to Power 12v accessories. (*Due to lower amp-hour capacity, not recommended for Street-use automobiles.)

The Antigravity Advantage

The ATX20 is a Standardized Size used in a large number of Powersports Vehicles such as Touring Motorcycles, UTVs, ATVs and more. Often times customers may modify, or add extra accessories to these vehicles and need a more powerful battery with more Amp Hour Capacity. This is where our HD models offer over TWICE the capacity of competitors Lithium Batteries of the same size! They also come with a Voltage Indicator test button on the battery so you can easily check its charge level. If you want to also track your battery condition and status via Bluetooth, you can use the Lithium Battery Tracker.

4 TERMINAL DESIGN

First Motorsports Battery with FULL Battery Management System.

New 4 Terminal Design for easy installation in any vehicle.

FEATURES

• Most Advanced Lithium Battery on the market.
• The first FULL Battery Management System (BMS) including Over-Discharge, Over-Charge*, Thermal Protections and Cell Balancing.
• LONGER LIFE: Up to twice the lifecycle of lead/acid, and other Lithium batteries due to full Battery Management system.
• HI POWER: Up to 2 Times the Cranking Amps of similar sized lead/acid batteries. Better Starting and higher voltage at start-up.
• ULTRA LIGHTWEIGHT: Up to 70% lighter than equivalent lead/acid battery. Up to 15 lbs in bikes or 45 pounds in Race Cars.
• NEW 4 Terminal Design allows easy installation in any vehicle. Fits right or left hand Negative or Positive connections. No more looking for the correct Terminal locations in certain bikes or cars.
• LOW SELF-DISCHARGE: Antigravity Batteries do not self-discharge like Lead/Acid Batteries. They can hold a charge up to a year provided there are no “Parasitic Drains” (accessories that draw power when bike is off, i.e. alarms, ECUs, GPS, heated grips, and other accessories the vehicle might have).
• DURABILITY: Our lithium batteries are shock and vibration resistant making them perfect for Racing, and other applications requiring a durable battery.
• MOUNTING: You can mount our battery in any orientation, there are no liquids to spill or drain out.
• ENVIRONMENTALLY SAFER BATTERY: No Acid or Heavy Metals such as Lead, Cadmium, or Mercury.

(*Over-Charge protection will not protect from faulty Big Dog OEM Charging Systems or a faulty/old Voltage Regulator spiking Hi-Voltages to the Battery. If you have an OEM Big Dog charging system or a Pre-1990s Motorcycle replace your voltage regulator; it is over 25 years old and most likely broken by now.)

BEST USES

• For replacement of all OEM Lead/Acid Batteries of same size.
• Excellent for stock motorcycles up to 2400cc.
• Excellent for Touring Bikes, Adventure Bikes and Bikes where extreme power and larger Amp Hour capacity are needed.
• Excellent for use in Race Cars of all types including large V-8 Racing Motors up to 700 Horsepower.
• Not for use with PWC (personal watercraft).
