What the Magnum X-1 needs

Every Magnum X-1 from the first 2015 model through 2017 starts on the YTX20HL-BS case, a 12-volt starter battery. Victory ships it with a lead-acid battery that starts to fade after two or three seasons of short rides and off-season storage, and that is usually the day a rider goes looking for something better.

The lithium drop-in is the Ionic S6: 720 cranking amps, 4.4 pounds, the same case in lithium. Charge it with a lithium-compatible charger or maintainer for the off-season and it outlasts the lead-acid battery it replaces by years.

What size battery does a Victory Magnum X-1 take?+

The YTX20HL-BS case, the same one on every Magnum X-1 from 2015 to 2017. The Ionic S6 is the lithium drop-in for it.

Will a lithium battery work in a Magnum X-1 without changes?+

Yes, on a bike with a healthy charging system: the lithium battery uses the same case, the same posts and the same cables, and it drops in where the lead-acid battery sat. Bikes older than about 2000 should have their voltage regulator and rectifier checked first, since a failing one overcharges any battery and lithium tolerates it less. Fill any gap in the tray with the foam spacers most lithium motorcycle batteries include.

Do I need a different charger for a lithium motorcycle battery?+

Use a charger or maintainer with a lithium (LiFePO4) mode. A lead-acid trickle charger can push the wrong voltage profile, and a desulfation mode can damage a lithium pack. A lithium-profile maintainer over the off-season keeps it topped without harm, and the battery loses only a few percent of charge a month sitting on its own.
