If you have a high compression V-Twin S&S engine greater than 110ci , you may exceed 680 cranking amps and will exceed our ETX36’s capabilities. The ETX36 series is limited to 680 max cranking amps. We do offer 2 upgraded options which is the ETX900 (900PCA) or the ETX1200 (1200PCA). Big Dog motorcycles need the ETX900 and custom bikes/V-twins over 124ci need the ETX900 or ETX1200.
Terminal adapters are included with this battery if you have a front mount connection with the standard size of 6mm.
