Default Using 2 batteries on a 12v trolling motor

I was wondering if any of you have used 2 batteries (run in parallel) to run your 12v trolling motor? Is there any difference in the time the batteries last vs. a 24v set up? I assume you get close to double the time you would with one battery but I am just wondering if there are any drawbacks or unforseen issues....thanks.

no drawbacks, i do it all the time, yes, it will increase your runtime by the capacity of the 2nd battery...

Agreed, Batteries might run cooler and you may actually get longer run time.

And overall length of service life might be better as your not running a single down as low. The less you run them down, the less sulfacation occurs. Of course getting them back on the charger ASAP helps as well. I think I'm going to hook mine up in parallel.

Doesn't matter how you hook the charger up, as long as a positive from the charger goes to positive on a battery, and a negative on the charger goes to a negative on a battery.
