charging trolling battery

[g32004]

I was looking at putting a battery bank charger in my boat from cabelas.
They have chargers with 6 amp 8 and 20 amp charges. I have a 42 lb thrust minkota trolling motor, and a 60 hp four-stroke yamaha outboard.
My question is do these bank chargers work well, and how long do you need to run your motor to charge the trolling motor. I normally only run my outboard 15 minutes out to the fishing spot then use my trolling motor. Then 15 minutes back to the dock is this enough, and what charger should I use.
I live on the water and its a pain charging the batteries everytime you use them.


thank you

Re: charging trolling battery

you are not going to get enough charge, if that's all the running you do. suggest spending the money of getting electricity to the dock. and using a conventional smart charger. also harbor freight sell a float charger, that you connect when you come in an forget about it. excellent for maintaining the battery over the none use periods.

You would only need to run your motor about 12 hours to recharge if it has a 30 amp alternator. If your like most and only run the main motor to get to and from you fishing spot then you need to recharge at the dock or at home.
For a single 50 percent discharged group 27 trolling motor battery charging with a 10 amp charger will take 12 hours or more to fully recharge.

I bought an inexpensive solar battery charger. Ebay has a selection - but note that these are trickle chargers and will take a long time to charge up your batteries. I've seen some in the 12Amp range that should work well (but are expensive).

Very expensive to say the least. A 12A solar panel equates to over 150 Watts will run you between $750 and $1000 not counting the solar controller.
