Change 6v batteries to 12v batteries

It takes two 6V golf cart batteries in series to give you 220AHs and will produce 12VDC for around 447 minutes (7.45Hours).

If you have three groups of these two series 6VDC golf cart batteries in parallel then you can get 660AHs and will produce 12VDC for around 1340 minutes (22 hours)

If you parallel 2 each 12VDC Trojan 27TMX Batteries you will get 205Ahs and will produce 12VDC for 350 minutes (5.8HRS)

If you parallel 6 each 12VDC Trojan 27TMX batteries you will get 630AHS and will produce 12VDC for 1050 minutes (17.5 hours).

Give or take a few...

Just remember the rule of thumb to re-charge a deep cycle battery using smart mode technology in three hours time is around 15AMPS DC current for each 12VDC battery. three groups of 6VDC golf cart batteries will need around 45 amps...
six each Trojan 27TMX will need around 90AMPS of DC charge... Your standard 55AMP convert/charger will have to be swapped out for a bigger one...

Then you have all that weight to worry about... 6V batteries weight around 62lbs each.. The Trojan 27TMX will weigh around 55 LBS each.

You will also have to use much heavier battery cables as well...

Lots of things to consider adding lots of batteries...

So Roy, it appears you know nothing about batteries! ....;)LOL!...just kidding...Good info!

Hi,

It sounds as if the reverse polarity fuses in the converter have been exposed to 24 volts. DAMHIK.

What make and model of battery was put in place?

Get someone in right away to correct the wiring on the twelve volt jars.

I seldom disagree with smk--but 12 volt jars are more suitable for large inverters than six volt. They do need to be wired in a balanced manner.

I'd be talking to who ever installed the batteries incorrectly, too. There is a possibility of other damage.

I don't have 12v power. The 12v disconnect by passenger side console and generator don't work. I thought I burned out the fuses and circuit breakers but everything is fine. The ignition has to be on for the 12v to work lights even when plugged in. The outlets work when plugged in.

The 6 batteries need to be separated, charged and tested.

If you have a large inverter I would go back to the 6x6 next time you need batteries.
Best value at Costco or Sam's Club. (self install)

Unless you have an understanding of basic wiring AI would suggest you hire a tech to come out and fix what ever problems there is and train you how to troubleshoot electrical issues without electrocuting yourself.

You can use the 12 volt bateries if you want to. They just wire in parallel but you need to be sure of your wiring because its different from 6, 6 volt.

If you never are without 120VAC shore power there is no need for more than one 12VDC battery. If you boon dock then 6 6VDC gold cart batteries will supply more power for a longer time. But they will also cost you around $150.00 each
