The ETX680 lithium battery has a lot of punch for such a light battery!

Use discount code MCI to get $10 off an Optimate TM-291 LiFePO4 charger with BMS reset, when purchased with an EarthX Battery.

This battery is intended for an aircraft engine of 400ci or less; 60 amp alternator/generator or less.

This is also an excellent battery choice if you have a touring motorcycle. If your motorcycle has a V-twin engine larger than 110 ci, then you should upgrade to the ETX900 as it delivers the additional cranking amps needed for a V-twin engine start.

The difference between the ETX680 and the ETX680C is physical size. The “C” is for compact.
