i-pilot trolling & battery charge time?
On the remote battery, I always carry two extras as when they go it sucks not having it. I had a remote that ate batteries quick, and was pretty new. I never use the light function. MinnKota replaced the remote, and it took care of it. Get most of season now... maybe, but when they go dead after a month or so, there may be something wrong.
I do the same. I use the kicker to push and the terrova on a setting that allows it to steer, 3-4 setting usually does it.
Lots of variables such as wind, waves and size of your boat.
I have a 16.5 ft deep v with double windshield, with a 5 mph wind, and 1 ft. waves.
My terrova, 24 volts with two new, size 27 batteries. After 3-4 hours the Min Kota read out says 1/4th discharged.
