These are the First Motorsports Batteries with built-in RE-START technology & a Battery Management System (BMS). The New 4 Terminal Design means DUAL POLARITY!
Direct replacement for these OEM battery sizes:
Cranking Amps: 880
Amp Hours: 30Ah (PbEq)
Weight: 5 Pounds 12.3 Ounces
The NEW Antigravity ATX30-RS battery is built with our groundbreaking RESTART Technology (built-in jump-starting) so you won’t ever get stranded with a dead battery again! The ATX30-RS is a High-Power Lithium battery to replace the YTX30 OEM Lead/Acid Battery, as well as some YIX and GYZ models.
The new ATX30-RS is an extremely lightweight and high-power Lithium-Ion replacement battery for the heavy lead/acid YTX30 battery found in many Motorcycles and Powersport Vehicles. The ATX30-RS offers the first FULL Battery Management System (BMS) found on a Powersport Battery and includes low-voltage cut-off, over discharge, over-charge, and thermal protections with real time lithium-ion cell balancing.
The ATX-30 Re-Start battery can also be used in Hi-Performance Automotive and Racing applications where extremely high cranking power and massive weight reduction in a very compact size are desired. As with most all our batteries, you can easily bolt on our Automotive Terminal Adapters for use in high performance automotive applications.
To give you an idea of the power of this battery, the ATX30-RS can easily Motors up to 700 Horsepower yet the ATX30-RS weighs LESS than 6 pounds! At a massive 880 Cranking Amps in an extremely compact size, this battery offers the most power in the smallest package you can find for your vehicle.
(*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 years old and most likely broken by now.)
***USE A LITHIUM ION CHARGER TO AVOID DAMAGING THE BATTERY***
Please Note: For custom V-twin applications over 103 cubic inches or when a higher compression, modified motor is being used we do not recommend RE-START batteries due to the extremely high current draw of larger V-twin motors.

Excellent for Harley Davidson Touring Bikes and other large Touring bikes that use the YTX30 size batteries.
Excellent for use in Performance and Race Cars of all types including large V-8 Racing Motors up to 800 Horsepower.
Please check the RS-30 Lithium Automotive Battery when more power and capacity is needed.
Please Note: if you own an older classic bike from mid 1980s and earlier you must update the charging system to a modern solid-state voltage regulator. Damaged or excessively old voltage regulators can over-charge and damage lithium batteries and cause smoking and melting of battery. This is NOT a fault of the battery!
