Never get stranded with a dead battery again. The Antigravity ATX30-RS is a high-power, lightweight lithium-ion battery built with groundbreaking RE-START Technology — the world's first battery with built-in jump-starting. It's a direct replacement for the YTX30 OEM lead/acid battery found in Harley-Davidson Touring models, as well as some YIX and GYZ sizes.

At a massive 880 cranking amps and just 5.75 pounds — up to 70% lighter than the equivalent lead/acid battery — you're shedding serious weight off your bagger while gaining starting power that can crank motors up to 700 horsepower, plus better handling and even shorter braking distances.

RE-START Technology — Built-In Jump Starting:

The Antigravity ATX30-RS RE-START battery is a game-changer for touring riders. It constantly monitors its own charge level, and right before it would normally die completely, it puts itself into a sleep mode — saving just enough reserved energy to start your bike one more time. When you're ready to go, just press the RE-START button right on the battery, fire up the engine, and ride away. That's it. No jumper cables, no calling for help, no waiting on the side of the road. For guys running a lot of accessories on a big touring bike, this is the kind of feature that pays for itself the first time you need it.

Hard-to-Reach Battery? On a bagger, the battery is buried. Pair this with the Antigravity RE-START Remote accessory and you can activate the RE-START feature through your existing SAE charging pigtail — no removing your seat or side covers. Want to keep an eye on your battery's status from your phone? Add the Antigravity Bluetooth Battery Tracker.

Features:

• RE-START Technology — World's first battery with built-in jump-starting. Press the button and go.
• Full Battery Management System (BMS) — World's first powersport battery with complete low-voltage cut-off, over-discharge protection, over-charge protection, thermal protection, and real-time cell balancing
• 880 Cranking Amps — Up to 2X the cranking amps of similar-sized lead/acid batteries for stronger starts and higher voltage at start-up
• Ultra Lightweight — Just 5.75 lbs, up to 70% lighter than equivalent lead/acid batteries
• Longer Life — Over twice the lifecycle of lead/acid and other lithium batteries thanks to the full BMS
• 4-Terminal Design — Fits right or left hand, negative or positive connections for easy installation in nearly any bike
• Low Self-Discharge — Holds a charge in storage up to 3X longer than lead/acid (check every 4-6 months, or sooner with parasitic drains like alarms, GPS, ECUs, or heated grips)
• Safest Lithium Chemistry — LiFePO4 technology with no acid or heavy metals like lead, cadmium, or mercury
• Shock & Vibration Resistant — Built tough enough for racing
• Mount in Any Orientation — No liquids to spill or drain

Specifications:

• Cranking Amps: 880 CA
• Amp Hours: 32Ah (PbEq) / 16Ah (Actual) / 204Wh
• Weight: 5.75 lbs
• Case Size: 6.5" x 5" x 6.89" (LxWxH) — YTX30 case

Direct OEM Replacement For:

YTX30, YTX30L-BS, YIX30, YIX30L-BS, GYZ32HL

Best Uses:

• Direct replacement for all OEM lead/acid batteries of the same size
• Excellent for everyday use in bikes up to 2500cc
• Great for extra large, high-performance V-Twin motors
• The go-to choice for Harley-Davidson Touring bikes and other large touring bikes running the YTX30 battery size

Important Notes:

• Large V-Twin Applications: For custom V-Twin builds over 103 cubic inches, or high-compression/modified motors, the RE-START version is not recommended due to the extremely high current draw of these motors. Contact us about the standard YTX20, YTX12-24, YTX12-20, or V-10 models instead.
• Use only a lithium-specific charger with this battery — never a standard lead/acid charger
• Over-charge protection will not protect against a faulty or aging voltage regulator spiking high voltage to the battery
• Not for use in street automotive applications.
