Product Identity

The Antigravity ATX12-RS is a 6.1Ah lithium motorcycle battery with built-in RE-START jump-starting technology. It directly replaces YTX12 and YTX14 lead-acid batteries in motorcycles, powersport vehicles and generators. The unit weighs 2.6 lbs and fits the standard YTX12 case dimensions of 5.9 x 3.38 x 5.19 inches. It suits riders who want a lightweight, maintenance-free power source with an integrated safety net.

Upgrade Context

This battery replaces heavy lead-acid YTX12 or YTX14 units that lack self-recovery features. The jump is worth it when you want to eliminate the risk of being stranded by a dead battery and reduce weight by several pounds. The built-in BMS provides low-voltage cut-off, over-charge, over-discharge and thermal protection that basic lead-acid batteries do not offer. It also covers 12 OEM battery sizes for broad compatibility.

Build Integration

The battery can be mounted in any orientation, freeing up layout options in tight battery boxes. Its lithium iron phosphate chemistry and full BMS remove the need for external management hardware. The RE-START button on the case lets you wake the battery without tools or jumper cables. It delivers 360 cranking amps for reliable starts in cold conditions. The 12 amp-hour lead-equivalent rating supports standard vehicle electrical loads.
