Have bow mount trolling motor powered by two 12 volt batteries.  To recharge can I hook up to positive on one battery & negative on the other one & charge both at same time?
Thanks

 I dont know your the answer to your question.  Spend the $ and get a 2 bank charger.  Safe, simple, quick.

YES, I am that foolish!

Yes get a two-bank charger safe and simple...

Altough this may work ,I would think you run the risk of over charging one of the batteries...I don't think it would be cost effective to to be replacing deep-cycle marine batteries every so often.

you can hook up the batteries and leave them positive to positive and negative to negative, it remains 12 volts, but double the amps, so the batteries last twice as long. it's the only way i can fish all day with mine.

A quick question while we are talking about trolling motor batteries.  If its a windy day or even not that windy my trolling motor battery only lasts 4 or 5 hours and it is brand new.  I was wondering if anyone has any advice on this or do I just need to get a different battery?

Let me get this straight as I'm dumb.  Hook up positive to pos. on one battery & neg. on Neg on the OTHER battery and double the amps?  They are brand new.

Connecting the batteries in parallel doubles the capacity (amp hours).  The voltage reamins at 12v.  When doing this, you should try to have batteries that have roughly the same capacity.  If you connect a normal 12v charger to two batteries connected this way, I don't think the overcharge protection will work properly.  You might just damage one or both batteries.

Batteries connected in series doubles the voltage (24v) and keeps the same capacity.

Your original post indicates that you have two batteries running the motor.  Is the motor a 12v or a 24v?  That is kind of important.

What size is your trolling motor how big of boat are you pushing around..example a 55 pdf pushing an 18 ft boat requires alot of battery power however if it's only a 16 foot boat you'll get more life out of it

The boat is still in winter storage (I know I need to get it out already and get fishin) and I am not exactly sure the size of the trolling motor but the boat is a little over 21 ft.

An onboard charger is the only way to go.  i got one from Cabellas last summer and it was the best purchase I've made in a long time.  No screwing around with a regular battery charger, just plug it in when you get home and forget about it until the next time you go out.  It was reasonbly priced like $129 or so.  only thing I would have done different is to get a 3 bank instead of a 2 bank.  Not much more $ and that third bank comes in handy if you run multiple sonars, marine band or stereo all on your starter battery.

The answer to your question is yes but it will take twice as long to charge if wired as a 12 volt.  If your batteries are wired 24 volt you need a charging bank or a pair of cables run to each battery individually.  I run a 3 bank charger with 3 Deep Cycle Batteries and 1 Marine starting battery.  I typically never run low on juice on a full  12 hour day of fishing and trolling.  2 large Deep Cycles run the 24 volt trolling motor, each battery has its own 10 amp pair of cables the last (3rd) bank or set of cables goes to a Deep Cycle that runs all electronics, live wells, radios  fish finders etc. (this also tends to solve radio interference with the outboard if any)  The outboard gets its own Starting Battery and is maintained (recharged) by the outboards stator only and only gets used for starting purposes.  Each winter the batteries are all pulled out brought inside and setup with trickle chargers as the boat gets below zero outside.  I tend to have to replace the trolling batteries every 3years the others make it to 4 years+ until I just replace them to be safe. 

I don't spend alot of money on them either I just buy the Walmart Yellow Maxx batteries and they last just fine.  Most people don't know that many of the batteries out there are made by Johnson Controls and just given a different sticker. ie: Walmart Everstart,  Sears Die Hard Gold ,Auto Zone (Duralast Gold) Eveready Interstate Mega-Tron Plus Toyota (TrueStart) Mitsubishi (Diamond Car Care) (Autocraft Titanium) Costco (Kirkland Signature) Pep Boys (ProStart & Energizer)
btw, Johnson also mfg. Optima brand. of course the Optima is hands down a completely different kind of battery and not compairable to a deep cycle wet cell battery.  When buying a battery look for the Mfg Date just like you do when you buy milk some will sit on the shelf for a year before you the unsuspecting buyer picks up your not so new battery (very common at the begining of a season.)  I usually get one that is no older than a month.

Just keep them topped off with water and try and not run them down passed 50% this really shortens the life of the battery always recharge as quickly as possible leaving them run down for 5-6 days then plugging them in the night before you go fishing again... generally not good for the battery.  Running the trolling motor hard also can boil the water away from the battery so check the water level out every so often ( I am guilty of neglecting to do this and have learned the hard way)  I unhook the boat and  plug the onboard charger in and its charged and ready to go usually completely within 8 hours.  A onboard charger rapid charges the batteries then can top them off with less amperage and then maintains them with a trickle charge achieving somewhere around 14.5 volts when done alot better than a cheap car charger ramming the battery with volts until done then kicking off.  Hope this helps with any battery issues some may have.  Tight lines........

A 21ft boat is a lot of boat to move around in the wind...a 12v trollilng motor won't last long especially if you're cranking it up past 6 on those windy days...honestly you should have at least a 80lbs 24v at the minimum is your boat fiberglass...if so that's a lot heavier then aluminium....I new trolling motor by be a wise investment like  said if your running those batteries hard they won't last long.  Hope that helps.

Trolling motors and Batteries

I have a 16 ft deep hull bow rider with my fishing seat in the front, I did a motor search on Minn Kota and it came back with a bow mount 55 lb. thrust 12 volt motor but I am going to put in a pair of batteries in parallel but need help with the batteries capacities. I was looking at 2 100 ah batteries but am unsure if that's enough to get me through 8 hours in a day or not, can anybody help me?

go with a 24 v system - your better off - 2 batteries parallel will not last as long vs. a  24 system.    The reason is that the 24 or for that matter the 36 draws less amps then a 12 - period   Just p/u a 24v and a 2 standard series 27 batteries 180min- and you should be good to go. 

Stay thirsty my friends

Wales, you answer your question, yes you can do that or just charge one while hooked to the other, you will be fine.

Strongly agree.  That extra power while rarely necessary certainly does offer one much more control and piece of mind on the really windy days.  Also if one fishes some of the smaller "no gas engine" lakes you can still troll cranks with a 24V electric.

Pard went from a 55# 12V to a 70# 24V and the difference in battery life and control, especially on the windier days was simply amazing.  It allows a guy the confidence to fish where the fish are even if that means a windy shoreline where the waves are crashing in, knowing you've the power to simply point it out to the middle and power out without having to start the main motor is very re-assuring.

This moment is a paradox, it's the oldest you've ever been as well as the youngest you'll ever be.
