Just upgraded to 6 volt

People who demand high performance inverter/microwave performance should seriously consider high CCA AGM batteries which in that mode will kick the snot out of any flooded battery of equal size and weight.

The problem is that most RV'ers learn via the school of hard-knocks. They design, they build and come up short.

But if a boondocking microwave is in the future for you, and battery space is limited. Forget flooded anything. 2 group 31 AGM batteries will markedly outperform 4 Trojan T-125's. The word MARKEDLY is not used loosely here.

Forgot to add: The AGM will blow a flooded 31 in the weeds as well.

The posts immediately above are great by the way. I thought I'd amplify and elaborate.

Agree completely. We do use a microwave, a panasonic true inverter that varies magentron power rather than cycling on and off. at 50 percent power needs about 80A. Running this off two GC is an excercise in frustration, as you point out. unless they are near 85 percent or more charged, the voltage drop will kick off the inverter. with 4GC it's good to around 60 percent. But then we only occasionally run the microwave, and when used for a few minutes at most. so living with the GC drawbacks given how we boondock is in our case a reasonable accomidation. But it is not a good fit for this few percent of our use, but we know how to live with it.

yes, those 4 trojan t-125's I have won't even give the cranking amps ONE of my 65A diesel truck batteries gives. And they aren't AGM's.

But if you like lots of draw often, and long periods, I agree completely. GC for sure are the WRONG choice for that application,
