Our 36V60Ah lithium battery is a popular choice, with successful installations on over 150 types of center-console boats, ensuring over 8+ hours of runtime for boats up to 34ft in calm conditions. For larger boats or those needing all-day power in 2'-4' seas, our 36V72Ah or 36V105Ah systems are recommended. We've designed these three tiers to cater to different needs and conditions, ensuring you get the most out of your trolling motor system.
