Seems like the old batt that came with my bike last year ain't holding up anymore. Appreciate input on experience with the Big Cranks...considering the ETX15, ETX16. 220 and 325 cca respectively.

Anyone with an FLH and the stock right side battery box use those and either have issues or can say "yup fits perfect!"

 

For a stock motor you shouldn't need any more than the regular big *** battery , any decent AGM or gel should do you fine . Wouldn't spend $$ you don't have too .
