How to hook up batteries parallel???

8 posts in this topic

I have a 12 Volt trolling motor and carry two batteries in the boat. I would like to hook my batteries up to run parallel so it draws off of both batteries at the same time? Do you just need to run a connection between positive to positve and negative to negative and then connect the trolling motor to one battery? Thanks for any help/advice.

+ to + , - to - hook hot to + on battery 1 ground to - on battery 2, this will assure and even draw when used. I just use battery cables from Wal Mart to connect the batteries.

To increase voltage connect Battery 1 - to Battery 2 + ... If using 12 volt battery you will add 12 volts with every battery you add to the series.(2 * 12Volt= 24, 3 * 12Volt= 36 and so on) Then hook your hot to the open + on the first battery and your ground to the open - on the last battery.

yup........thanks for all the tips and hints. Went and got a couple of cables and hooked it all up this afternoon. Works like a charm!! Anxious to get on the water and see if it really makes a difference in battery life.

It will help a ton with run time, I ran my last couple boats on a dual 12V system. Now I run a 24V and wouldnt trade back for nothing.

    • The past week has had me having multiple close calls and missing a brute at 45 yards.  Tonight I talked my dad to give it another try and there were birds in the field when we got there.  Birds ended up leaving as we tried to sneak in.  A short 20 minutes later they were back and we watched and worked the big group of toms and hens for more than 2 hours before we got one to commit.  Dad shot him with his 20 gauge at 48 yards,(this thing shoots an awesome pattern).  The 3 year old was down and only flopped a few times.   Nice 1+ inch spurs, 10" beard and heavy.  A good evening for sure!
    • Sorry to disappoint guys, but this tom was not my first bird of the season. Apparently that's part of the rules. The score won't count towards the team. I don't have any measurements for the jake I shot so we will have a zero from me.    At least my freezer is full. 
    • Way to  go 1957 !! Congrats!!
    • sugar is not a drug. 
    • Another good day today out on Superior ,,,, Had my first double and triple in the new rig today ,,, the day didnt start out with perfect weather but the fishing more then made up for it ,,, The mud  covers a lot of water but fishing the tea  colored water and edges of the mud paid off ,,, the cohos grew 5 inches  from eating this years smelt,,,, had some go 23 inches today 
    • Say no to drugs, like sugar.  Yes, sugar is a drug.
    • I won't be able to post the scores for this week until maybe Wed. so if someone else wishes to do so feel free to do it. In fact for the entire summer season I'm going to be pretty much hit and miss. So don't count on me the lake is calling and I have no computer there. My scores will drop like a rock unless luck prevails.
