• To charge all of your boat batteries while towing, consider our Tow-In-Charge & 12/24/36v Smart Box combo.
  • The Tow-In-Charge charges your 12-volt cranking battery to 12 volts, then activates your 12/24/36v Smart Box to charge your 12 volt trolling motor or accessory batteries on the go.
  • No more dead battery surprises when you get to the boat launch and no more running out of battery power on the lake.
