Group 27 AGM trolling motor battery

[Hydro]

Optima's locally didn't have the same CCA's and AH's as my whipped out Big Momma that went TU this weekend after three years (not bad)...

Cabelas, Advanced Auto, Academy, and Bass Pro have their own lines (all made in China )

Trying to dump some poundage while upgrading the TM battery, going from lead acid to AGM ... Not seeing any Opti's that look up to the task ??? At least half the stroke of conventional lead acids , based on AH's ...

Real life experiences appreciated ... Sponsorship and loyalty to one brand or the other not needed ... Just looking for "this worked for me" comments ...

Minn Kota 55lb digital is what we are feeding here ...

Thanks,
Hydro
