Dual 6V golf cart batteries on White Hawk

carloss · 03-08-2019, 11:05 AM

Today I finished replacing the single 12V battery on our 2018 White Hawk 26RK with two 6V golf cart batteries. The factory cables were too short to reach the batteries, so I used a dual PowerPost cable connector to connect the factory cables, and the two cables I built to reach the batteries. I did not want to mess with the factory cable connectors. That way we can go back to factory settings and a single battery if we ever decide to upgrade the trailer, without have to cut and replace cable terminals. While I was at it, I also added a battery disconnect to the battery box. I "borrowed" part of this idea from an installation I saw at another forum.

Nice clean installation! I would use some shrink tubing on the open ends of the insulation tubing so water doesn't collect in there.

Thank you. The insulation tubing is open at the bottom so the water will just go trough it, but I like your idea. I did spray all the terminals and cable ends with silicon to prevent corrosion.

Very clean. Thanks for sharing. Now you've got me thinking. Honey, can I have the checkbook?? Please.....

It's a nice installation!

I have a suggestion- Mount the disconnect switch so that the handle points DOWN in normal operation. It might avoid an accidental shutdown.

Also, if the disconnect switch handle detaches when the switch is off (mine does), put a tether of some kind on it, so it doesn't get lost or grow legs.

carloss,

Welcome to JOF

Battery bank installation looks great and will enhance boondocking trips.

Incorporating the battery supports over the top of the A-frame has it's advantages, especially not having to deal with re-locating the OEM wire bundle crossing over the existing support rails.

That's an awesome box. I wish that I had picked one up when I converted to two 6V.

Looks nice. I would, otherwise it would drive me nuts, paint the battery box support beams black so they match the trailer frame. Just my .02.

Yes my OCD wants me to paint the support beams black.

Very nice1 Where did you find the battery box?

Good installation Carlos, although I believe the cut-off switch should be on the positive leg.

Either cable, more of a personal preference.

I would just make sure you don't disconnect the battery when traveling or else your breakaway brake box won't operate.

Looks Good!!
So, Enlighten me here......How much/what are the advantages of the 2 batteries?.....other than Golf Cart Batteries last longer on a charge

Do you need to do anything different for charging them vs. a 12v?

sorry for my ignorance.

Golf cart batteries are constructed internally for deep cycling use.

Using two 6 volt batteries is the equivalent of one really big 12 volt battery.

Nothing different is usually needed to charge them.

Are the bolts / bracket that are holding it to the frame strong enough to hold it in place?

Nice setup. Great battery box and shutoff switch.

We upgraded to a pair of 6v's on our 26BH as soon as experience showed that the single 12v wasn't appropriate for overnights off the grid with the furnace running.

The only thing I would criticize about your setup is the metal support system. We went to a local welding shop and had them weld on a pair of angle irons for battery supports. The existing supports attached to the bottom of the tongue were lacking space, and appeared a little light for the new battery setup.

We had the welder use heavier angle iron, mounted on the top of the tongue. We did the primer and the shiny black paint, and the install now looks like it came from the factory, and is extremely robust. The charge from the welder was only $45.00 for the materials and labor, and they did it while we waited.

Very nice. We have the same battery box and its been great for the last 4 years.
