That's definitely the best trolling motor battery for the price. We've ran them for years and is always a top choice when guys ask about trolling motor batteries. But for cranking/dual purpose needs, its not enough for us and most newer rigs with multiple big screens, pumps, poles etc. Last thing you want is to be stranded cause of a weak cranking battery at the end of the day. The Duracell barely meets minimum cca for most 250 outboards. Add in all the electronics and accessories, you're susceptible to issues at the end of a full day
