The Antigravity Batteries ATX20-HD and ATX30-HD are part of our HD (Heavy Duty) Series, 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 and more. Simply put, these are the most powerful and compact batteries available from any manufacturer.

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. 

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! 

FEATURES

The first FULL Battery Management System (BMS) including Over-Discharge, Over-Charge*, Thermal Protections and Cell Balancing.

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 7kg in bikes.

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.

DURABILITY: Our lithium batteries are shock and vibration resistant making them perfect for Racing, and other applications requiring a durable battery.

(*Over-Charge protection will not protect from a faulty/old Voltage Regulator spiking Hi-Voltages to Battery. If you have a Pre-1990s Motorcycle replace your voltage regulator; it is over 25 year 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 1700cc.
