bad battery... I know dumb question, but is it wired correctly?

I checked the water in all the cells and only found one that was low. It wasnt even that low. I hVe the batteries hooked up in series, positive of one battery hooked to the negative of the other and trolling motor cables on the other end.

It is either the battery, or your not getting a good charge, do you have a voltmeter? A good self test is to run the motor and check the voltage at each battery, it should fall a little while running, say from 13 to like 12, I am guessing you will see a drop to like 8 or something...

I'll check tonight. I am afraid one battery is weak

That is my guess as well..
