Antigravity ATX30-HD 12V Motorcycle Battery 970CA (48Ah Heavy Duty)

Antigravity ATX30-HD 12V Motorcycle Battery 970CA: 48 Amp-Hours in the Touring Case. Nothing Else Comes Close

The ATX30-HD is the biggest battery Antigravity makes for a motorcycle: a 24Ah lithium pack (48Ah lead-acid equivalent) and 970 cranking amps in the YIX30L footprint, at 7.81 lbs. That is the battery for the 117 and 131 cubic-inch builds, the high-compression motors where Antigravity does not recommend a RE-START, and the baggers whose fairings carry more amplifier than some houses.

There is no RE-START reserve on the HD. In its place you get roughly twice the capacity of other lithium in this size, a deeper usable discharge, and a lighted voltage indicator on top: press it and you know where the battery stands.

Why the ATX30-HD

• 970 cranking amps for big-inch and high-compression V-twins
• 48Ah lead-acid equivalent (24Ah lithium, 307Wh): the most capacity in a YTX30 case from any brand
• 7.81 lbs replaces a 21 lb lead-acid battery
• Replaces YTX30, YTX30L-BS, YIX30, YIX30L, YIX30L-BS and GYZ32HL
• Push-button voltage indicator; 4-terminal design fits either terminal layout
• Full BMS: over-charge, over-discharge, thermal protection, cell balancing

ATX30-HD Heavy Duty Specs for Nerds

Fits Harley touring and trike models, BMW R18 and other bikes on the YTX30 / YIX30L case. If the motor is stock and you want the built-in jump start, the ATX30 RE-START is the pick; the HD is for capacity and cranking headroom.
