Trolling motor service is basicaly light duty and the related chargers are not all that powerful. That all works in your favor.

Matt


current trolling motors run up to 36 volt models. so I am advised by my professional consultant. and slamming the troller wide open for a day, then slamming it on a charger overnight for the next day is not "light duty".

I certainly agree however that the majority of the folks do use them in relatively "light" duty. but my main question was concerning the inherent explosion built in when two 12 volters are used in parallel.

I see in the Bass Pro/Cabelas catalog that they have three types of batteries.starting; deep cycle/starting; and deep cycle.
are you naysayers calling them liars or are you just mistaken.

One thing to think about.. When you take two 6 volt batteries and put 'em in series like this:

-{6v}+-{6v}+==== 12 volt

What you have is a SINGLE 12 volt battery.

You put two pair in a series/parallel

-{6v}+-{6v}+==== 12 volt
-{6v}+-{6v}+==== 12 volt

You still have one 12 volt battery (around 450 amp hours).

You got this right. I read a lot of posts from internet battery experts on here, and they are knowledgeable, but no one ever gets this part correct. I am NOT saying I am an expert.

For a few years I worked with a guy that did PMs on strings in power plants and sub stations. The individual unit is a jar, the entire string is a battery.

When I was working with him, we did batteries up to 250 volts made up of 2 volt jars (which are really just huge 2 volt plastic containers).

That is where the term "jars" comes from, it actually is correct. The testing tools in THAT industry still call the individual cells jars, and the whole group is a string, with the connectors called straps.

Even today I have access to a Midtronics battery analyzer. I do enjoy it, if nothing else just so I can still play with it.

As I said, I am NOT an expert, trust me, MEX knows WAY more about this stuff than I do.
