NEW! ATX20-HD

HEAVY DUTY Series

OEM Size Lithium Battery (Direct Replacement)

Antigravity Batteries is proud to introduce the NEW ATX20-HD and ATX30-HD. The NEW HD (Heavy Duty) Series was specifically designed to offer SIGNIFICANTLY more Amp Hours (6 Ah more per battery) and Power than the original versions of the ATX20/30 to meet the special needs of those looking for the most compact yet powerful battery. These Batteries are intended for those special applications like heavily accessorized Touring Motorcycles, Racing and Street Performance Vehicles, Experimental Aircraft and more. Simply put, these are the most powerful and compact Batteries available from any manufacturer.

The NEW Heavy Duty ATX20 and ATX30 do not have our RE-START built-in jump-starting feature but offer a deeper level of Discharge for more usable Capacity and more Power for Cranking. They also offer a FULL Battery Management System (BMS) to 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.

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.
