12-24 volt???

[BLUESHARP]

I`m running 2 batteries in my boat,one for starting the other for accessories.I have a Deckhand anchor cranker on the accessory battery.I would like to buy a 24 volt trolling motor.Do I need to buy 2 more batteries or is there a way to buy 1 battery hook it up to accessory battery and get 24 volts off one end and 12 volts off the other? Do they sell some type of transformer that would break it down to 12 volts again? Hope I explained myself clearly.

Hook accessories up to the starting battery and run just the trollers off of the 2 other batteries.

Yes you can do as you explained and buy one battery and use your accessory battery.
The 12 to 24 volt conversion happens at your trolling motors 3 prong plug. Complete instructions should come with the motor.
