For each motorcycle shown Shorai often, but not always, has three battery options. The first is the Standard Recommendation, second is the Race Recommendation and third is the Duration Recommendation. See below for the explanation of each of these recommendations.
- The Standard recommendation is the best overall pick for most applications, and has been selected to give strong cranking performance and long lifespan. For comparison sake, the LFX9A1 is 5.65 lbs. lighter than the lead-acid Yuasa YTZ10S and is ProCycle priced at $124.95.
- The Duration recommendation is for those who want the strongest possible cranking performance and lifespan, and don’t mind a slight increase in weight and cost compared to the Standard recommendation. Users with extra electrical accessories - like stereo systems used regularly when the vehicle isn’t running - may also choose the duration suggestion. The LFX 14A1 battery is 5.32 lbs. lighter than the YTZ10S and ProCycle priced at only $149.95
You can charge your Shorai battery with a regular battery charger but if you want the very best for it, this charger is designed for optimum performance by balancing the individual cells in the battery.
