Can I switch to 2@ 12 volt batteries without problems with the power inverter or do I have to change or upgrade power inverter.
You do really mean inverter, or converter? No changes to your CONverter, which charges your batteries.

Yeah, there's a few on here who do that. I guess that originated from the first batteries.. Leyden jars. Also, shorter word than batteries.

Matt,

How about explosion/issues with 4x 6V for 12V?


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).

I run a six volt pair in parallel with 3 different size 12 volts.
I've never had a battery explosion (I'd like to run all one size on the 12 volts but. alas.. store was sold out)

But.. IF one, espically the smallest, shorts, an explosion is possible.. Now least you worry.. the "Exploison" is about as powerful as a bubble gum popping. but it scatters all the acid in the battery which is why you need to do a soda wash.


Home is where I park it.

Most 6V GC batteries used in RVs are 230A giving you 12V at 230Ah. Most 12V RV batteries are about 80Ah giving you 160Ah. Marine deep cycle batteries are a compromise and not much better than starting batteries.

If you buy your batteries at Sams Club or Costco, a pair of GC2 golf cart batteries will cost less and as stated, give you more power.

There are boats and then there are boats. My trawler had 3x 8D batteries, large heavy puppies. Never had a problem but batteries do explode but not to often IFAIK.

Lead acid batteries explode when over charged/over discharged (welding/shorted) and/or the liquid level is low.

Not all batteries are alike.

12 volt batteries. most of these are MARINE/deep cycle or MARINE/rv Now Trolling batteries are True DEEP CYCLE.

IMHO, any battery that advertises Cold Cranking Amp (CCA) or Marine Cranking Amps (MCA) is NOT a true deep discharge battery.

I have never seen or gotten paid to clean up after a bank of 6V that had problems.

Bumpy,
I have seen one (and only one) explosion in a trolling motor bank of parallel 12V. That happened when the owner tried to use it to crank the big motor on his bass boat.

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