What kind of battery would i need to power a trolling motor?

The link to my exact motor is http://www.amazon.com/Minn-Kota-Freshwater-Transom-Trolling/dp/B0017122V6/ref=pd_bbs_sr_1?ie=UTF8%26amp;s=sporting-goods%26amp;qid=1239418774%26amp;sr=8-1 and it will be the only motor I use on an eight foot long wooden boat and I will use it constantly.What kind of battery would i need to power a trolling motor?
Get a "DEEP CYCLE" battery. They are designed to be run down and recharged like in the way at trolling motor will treat a battery. A regular battery will not hold up as well. Buy the best you can afford.What kind of battery would i need to power a trolling motor?
Constant use of an electric motor,if I understand you, will require lots of amp hour batteries. On a rubber dingy the motor will last from 2-6 hours depending on the speed you run and a dingy is much lighter than a wooden boat. The responses of a deep cycle battery with a maximum of amp hours is right on with a 'smart charger' that charges at 3 stages would be necessary when boat is tied up. Otherwise a very long extension cord will be required for long trips or constant use.



One approach would be a solar panel wired to the battery Not knowing the configuration of your boat so I can only guess but it may be possible to mount the solar panel elevated at the stern. The size or specs for the panel gets quite technical so I would contact experts in the field of batteries and solar charging. I hope this helps. .What kind of battery would i need to power a trolling motor?
Get the biggest heaviest marine deepcycle you can afford and have room for. Get a good charger with "float mode" or "maintain mode" (*not* the same as a "trickle charger"). Charge it soon as possible after every use on a 10- or 12-amp setting.

I agree with David's estimate of run time -- you can get more than twice the run time from two identical batteries wired in parallel (+ to + and - to -), make sure they're matched as to age, construction and capacity, otherwise the weaker will drain the stronger.



solar wouldn't be a bad choice as a maintainer, but with the current state of technology, the solar panels required to recharge a discharged battery would be prohibitively expensive, not to mention huge, I mean the size of a house.
