Another Golf Cart Battery Question

[boulderado]

I am getting ready to replace the original battery in our 2018 Keystone Cougar 24SABWE TT. I have decided to go with two of the Duracell Golf Cart GC2 batteries, $97 each at our local Sam's Club, plus core charge, I am sure. I ordered a new box from Amazon that will fit two of these.

Our trailer has a WFCO converter, model number WF8955. According to the specs it has automatic three-stage charging with output voltage modes of 13.2 VDC range “float” mode, 13.6 VDC range “absorption” mode, and a 14.4 VDC range “bulk” charge mode. Anything to be aware of with this type of converter and my proposed battery configuration? Also, any suggestions on which cable to purchase for connected the batteries in series? I want something solid.

The inside 'control panel' has indicators that shows battery status with just simple lights (E, 1/4, 1/2 etc). This is obviously pretty useless. Any suggestions on an easy fix to add a battery monitor of some sorts without having to do major rewiring? My handyman, who works as a small airplane mechanic, will be helping me with this so I won't burn the trailer to the ground.

As always, super-thankful for any and all input.

Give the WFCO one weekend to see if it will go 14.4 boost mode. Plan to replace it.

I would go 35 amp Boondocker MBA. https://powermaxconverters.com/product/pm3-mba/

If your old batteries preformed well during their lifespan, why do you need to monitor the new batteries more closely? Didn’t the old batteries have similar charging requirements?

- Nothing "different" to consider using 6V batteries in series. You're just turning them into a 12V battery.
Regarding cable for the jumper wires, whatever you use will likely be of the same or better quality than what is installed in the camper.
For an (estimated) 60A current, 6ga is sufficient. I'd probably go 4ga though, minimum. You can buy a couple short premade cables (2 or 4ga) at any auto parts store likely or find some on Amazon real quick, or make your own with some bulk cable and ring terminals.
Presuming the + and - cables existing are long enough to get to both batteries.

That WFCO will never reach 14.4 bulk charging. I'm on my 3rd WFCO and have never seen 14.4, only 13.8 ish. The batteries have to be way way down on charge for the 14.4 bulk rate to happen. Under normal use you won't see 14.4.
That's why people by a Progressive Dynamics charger so they can get a real 4 stage charger.

Are you going to add solar?
If so, your solar controller could give you the monitoring you want.
