You need to use a deep cycle battery with a trolling motor. If you use a starting battery, it will fail after the first couple of times that is gets close to being fully discharged. Unfortunately, deep cycle batteries cost more than typical automotive batteries.

You can go to Walmart or Costco and get a deep cycle battery for about $50 or less. If you want to run for a longer period of time spend the extra $10 and get a group 27 (larger in size and capacity) battery. Walmart has a great fully automatic charger (5/1 too for around $60 if you need one.

Hey Doc,
How would I hook up my down rigger and fish finder together with 1 battier or do I need to buy 2 ;D

You can use a single deep cycle battery for all of the electronics on your boat. You will need to invest in a good battery charger.

Get a Guest 3 stage 10 amp battery charger. Best I have ever owned.

When looking for batteries, try to buy the heaviest battery that you can afford. Weight=quality. The heavier the battery the better. This applies to deep cycle and starting batteries. I know it's hard to pass up those cheaper batteries, but trust me on this one! I'm speaking from experience. ;)

The way to look at it is,, how many amps does the trolling motor consume? lets say 5amps as an example, so if it uses 5amps and you buy a 5amp hour battery you could troll for 1 hour, if you bought a 50 amp hour battery you could troll for 5 hours and the battery would be dead, so do the math..

Also you shouldn't drain your batteries past 80% of there capacity otherwise you will damage them and cause pre mature failure..

Hope this helps..Sunracer
