He's not switching back, he was referring to converting the AH for his 6 v batteries into an equivalent 12 volt series hookup. Each 6 v Trojan is 125 AH, the series connection is therefore 12 V at 125 AH.

Your battery status monitor will always read full when you are charging since it is only reading voltage and the voltage is more than 13.3 volts from the converter or charger when charging. If you wait 12 hours after you stop charging, the panel will sort of indicate the state of your batteries according to the chart that has been posted numerous times on this forum. Not a good way to tell the status since most of us can't wait 12 hours to find out how much we have left in the bank.

After reading the WFCO manual, I'm convinced WFCO converters usually work as WFCO intended them to. But usage scenarios vary widely from one camper to the next, and the battery charging needs of one user are not nearly the same as the next.

The WFCOs are liked by the RV manufacturers because they are programmed very conservatively to avoid battery gassing and over-charging. And they use cheaper components, and are cheaper to buy. For example, the WFCO will not go into bulk mode unless the battery is pretty low, and for some users not at all. The WFCO, per the manual, will not go into trickle charge for at least 44 hours at a steady current output. That means that while camping, the WFCO essentially stays at 13.7 volts all the time unless you drag the batteries really low, and can trigger bulk mode. It also means slow recharging on a generator or shore power.

The PD is usually programmed more aggressively, and will go into bulk mode sooner and stay there longer. I believe some PD units can be manually forced into a particular charge mode.

On my A-frame the converter is also the power distribution panel, so replacement of the WFCO is not as easy. For our camping style, the WFCO is adequate. We put in two GC2 6V batteries (232 AH), and that is sufficient for 4 nights with the heater. We don't use inverter, generator, or solar to avoid the hassles of each. But we never spend more than 4 nights in any one place. Put the A-frame in the garage when we get home, plug it in for 3-4 days, and we are ready to go again. KISS camping - I like it.

Oh!! I see now since I read it right.

My 6v batteries are also 232 ah.

Stupid question. Of those of you that have had 12v batteries and 6v batteries, which have a better life span?

I had dual 12V size 24 batteries installed by the dealer when I bought the a-frame new April 2014. One of them went bad April 2015. I ended up destroying the other one before I realized what had happened.

I replaced them with dual GC2 6V Interstate golf cart batteries from Costco ($150 for both including tax). This was cheaper than 12V and gave me 232AH instead of 160AH from the12V. The 6V also fit the battery box better. Only drawback to me for the 6V is 40lbs more tongue weight.

After a year, the 6V are showing 12.8V at full charge.

6V golf cart batteries are built sturdier and typically can be discharged more. You can get equivalent 12V batteries but they tend to cost more. Easier to maintain 2 6V batteries versus 2 12V batteries as there are only 6 caps to fill/check.

I usually got 4-5 years out of 12v batteries. I'm into my 6th year with two 6v batteries, they are still going strong and have a resting voltage of 12.75

Excellent information, thanks. This explained a lot of questions I had on the WFCO.

Keep in mind not long a go deep cell batt only came in 6 volt Now you can get them in 12 volt look into the floor sweeper 12 deep cell's made by US Batt.
150 ah out a 31t x2 + 300amp hrs
