Default Re: Length of battery time on the water?

Display your resting voltage on your lowrance head unit as an overlay and when it goes to 11.5 it is time to start the motor and recharge for a bit.
Your VHF radio may also have a low voltage warning built in that will sound off when your battery goes below a preset limit so you don't get stuck in a no start situation but two batteries is almost a must do these days
