The easiest way to run them parallel is to install a switch and it is more covenant also

RECENTLY REPAIRED TROLLING MOTOR
APARENTLY I HAVE BEEN RUNNING MY 24 VOLT SYSTEM WITH ONE OF THE BATTERIES NOT UP TO PAR. IT HAS BEEN DRAINING FASTER THAN THE OTHER WHICH HAS MESSED UP MY MOTOR. I TOOK IT TO THURMAN HURST IN COON BOTTOM AND HE REPAIRED IT AND IT WORKS GREAT. THURMAN AND A FRIEND OF MINE THAT WORKS ON ELECTRIC WHEELCHAIRS, TOLD ME THAT ON A 24 VOLT SYSTEM IT IS VERY IMPORTANT THAT BOTH BATTERIES HAVE THE SAME CHARGE AND DRAIN EQUALLY.
THURMAN SUGGESTED TO ME THAT I USE TWO 950 CRANKING AMP BATTERIES BECAUSE THEY CHARGE MUCH BETTER AND EQUALLY THAN THE DEEP CYCLE BATTERIES.
ANY THOUGHTS ON THIS?

Maybe this will help some

A car's battery is designed to provide a very large amount of current for a short period of time. This surge of current is needed to turn the engine over during starting. Once the engine starts, the alternator provides all the power that the car needs, so a car battery may go through its entire life without ever being drained more than 20 percent of its total capacity. Used in this way, a car battery can last a number of years. To achieve a large amount of current, a car battery uses thin plates in order to increase its surface area.
A deep cycle battery is designed to provide a steady amount of current over a long period of time. A deep cycle battery can provide a surge when needed, but nothing like the surge a car battery can. A deep cycle battery is also designed to be deeply discharged over and over again (something that would ruin a car battery very quickly). To accomplish this, a deep cycle battery uses thicker plates.
A car battery typically has two ratings:
CCA (Cold Cranking Amps) - The number of amps that the battery can produce at 32 degrees F (0 degrees C) for 30 seconds
RC (Reserve Capacity) - The number of minutes that the battery can deliver 25 amps while keeping its voltage above 10.5 volts
Typically, a deep cycle battery will have two or three times the RC of a car battery, but will deliver one-half or three-quarters the CCAs. In addition, a deep cycle battery can withstand several hundred total discharge/recharge cycles, while a car battery is not designed to be totally discharged.
There are some good links on the site also

I use a Trollbridge combiner. Allows me to use two 12v batteries for 24v trolling motor and running the main engine. Automatically switches back and forth between 12v and 24v. Charges both batteries while running main motor. Works pretty well.

That is exactly what I was looking for a while back. How long have you used it?swatdog wrote:I use a Trollbridge combiner.

2 or 3 months. Seems to perform as advertized. Very easy to install and wiring diagram is very simple. Only used one 50 amp breaker on hot lead to trolling motor. Used 8 ga wire for a 12 foot run. Most recommend 6 but it is working fine and stays cool. I ususally only use thrust of 3-5 on a 10 scale.
