Today was the first day out on the water with our "new" boat. It's only powered by a trolling motor. It is a Motorguide Varimax 24v 75lb thrust motor and I have two EverStart Maxx Marine 29 deep cycle twelve volt batteries. We were out for about 2 hours (first time with batteries and trolling motor, they are all new) and the motor stopped working. The digital display on the trolling motor still worked, but the motor did not function. The circuit was correct and clean. I went home and charged the one battery and once complete I used a multimeter and got a reading of about 13.30 right after charging, the battery that was not charged yet gave a reading of about 12.4 (I thought 12.6 was normal.) When we hooked both of them up to the charger it showed a low battery percentage, but the volts were still "normal" (according to my multimeter), I assume. I am charging the second battery right now. What do you think my problem is the battery or motor, what should I do? We had to be towed back in on our first day on the boat...what fun. Also I'm using a DieHard charger on a fast 10a charge, is this correct or do I need a different charger/setting. Also do Deep Cycle batteries lose there charges and how fast. Do I need something to maintain the battery at all times?
Sorry for all of the questions, I'm kind of agitated and freaking out since it had to happen the first time ever out.
Thanks,
Zach
