The Antigravity ATX30-RS is a lithium-ion replacement for the YTX30-size battery used across the Harley-Davidson Touring line, with jump-starting built into the battery itself. It delivers 880 cranking amps from a 5.75 pound package, cutting roughly 20 pounds against the stock lead/acid unit while cranking harder in every condition.

The RE-START system monitors the battery's own state of charge. Before the battery can go completely dead, it puts itself to sleep and holds back a reserve of energy; press the RE-START button and the bike starts one more time. On a bagger where the battery is buried under the seat, the RE-START Remote triggers the same reserve through the SAE charging pigtail without pulling any bodywork.

Features

• 880 cranking amps, roughly twice the output of the stock lead/acid battery
• RE-START technology: built-in jump starting from a protected energy reserve
• Full battery management system with over-discharge, over-charge, and thermal protection plus real-time cell balancing
• 5.75 lbs in the standard YTX30 case, an installed weight saving of roughly 20 pounds
• LiFePO4 chemistry with very low self-discharge; holds a charge up to a year without parasitic drains
• Sealed construction, mountable in any orientation

Installation Notes

• Charge only with a lithium-compatible (LiFePO4) charger such as the Antigravity SC-2 or SC-4 Super-Charger. Lead/acid chargers, especially those with desulfation or recondition modes, can damage lithium batteries.
• The RE-START reserve is activated with the button on the battery case, or remotely through the bike's SAE charging pigtail using the Antigravity RE-START Remote.
• Check state of charge every 4 to 6 months if the bike carries parasitic drains such as alarms, trackers, or always-on accessories.
