Run time on your bow mount motor with one 12v battery?

Recommended Posts

Will one deep cycle 12v battery like the interstate SRM-27 run a 55 lb bow mount most of the day (6-8 hours) on a 14 foot aluminum Jon? Would love to be able to do just one for weight purposes. Starting this build soon. Thanks in advance for the replies guys!

As Wayne said yes, just hope it doesn't get too windy. I went out last weekend and ran my front motor dead and I'm running 2-12s in parallel. I will this is the first this has happened, but it did run them dry. It was 15 to 18mph winds and there were times I had to run it almost full out to keep moving forward. I was going to run just one for the same reason, but I already had the batteries so now I'm glad that I didn't.

2 6v batteries wired in series = 12v and will give more amp hours than 2 12v batteries wired paralell. We did this using golf cart deep cycle batteries before 24v trolling motors were available.

Look into a 55 thrust 24v trolling motor and use 2 12v deep cycle marine batteries wire in series, this would be your most efficient set up.

AGM batteries last longer than gel or wet cells with no mess handling batteries.

It's all about amp draw per hour vs battery weight. To reduce resistance with DC batteries use 6 gage wire from the batteries to the trolling motor.

X2 on the AGM batteries. Never heard of the twin 6v in series. Tryin to understand why, might have to do some reading

Batteries in series multiply voltage. A golf cart battery has a lot of AH.

I understand how a series connection works, I'm a diesel mechanic. Are the amp hours only more because they were golf cart batteries? Tom made it sound like any 6v batts in series would run more hours. I just assumed all he could find were 6v batts made for golf carts.

 

@WRB Can you clarify this for us? Thanks

If you put two 6V golf cart batteries beside a single 12V deep cycle battery, you will see the total physical size would have more AH.

Anything less is just that------less.

Do you use two small batteries for a diesel????

There are lots of differences between deep cycle batteries, plate size engineering to withstand being recharged multiple times. The batteries we used were 6v Trojan golf cart batteries and a pair would run a bass boat trolling motor about 12 hours in average windy fishing conditions. Trojan used the same technology in their 225 series 12v batteries and to this day a top quality wet cell battery.

Go and re-read his original post. He said 2 6v batts in series would run more hours than 2 12v batts in parallel. so the physical size has nothing to do with it. Unless the 6v gold cart batteries had more cells than the 12v.

im only curious if 2 batteries run in series give more amp hours than 2 run in parallel regardless of there voltage. Which is what it seemed he was implying.

This made me think. My best friend owns a business called "the golf cart outlet" 

 

wooooo!

One thing about the 6s is they are around 70lbs each so keep that in mind, that's why I didn't use them on my front motor.  Most of your front motor running will most likely be on the two or three lowest settings unless it gets real windy or it's a strong current, so your front batteries shouldnt impose a problem. Like I said I run 6v GC batteries for my travel motors or transom motors and they are 232ah which gives me like 4.5 hours travel time on full power. When you hook batteries in parellel you double the amps when you hook up in series you double the volts. Size of the battery and its plates will dictate running time, this is something that looked into hard before I spent time and money on my reservoir rig.
