Field test report of new AGM design

Been field-testing an interesting new 6v GC2 AGM design from Fullriver. Now I can talk about it.
The capacity is a typical 220 ah @C/20 but they weigh 83 lbs. Run them down to 0% SOC then recharge to 100%, roughly following BCI standards but at a slightly lower discharge rate of C/5 to C/8, got 1022 charge-discharge cycles at 100% DOD. I am very confident that their published numbers are conservative.
This is not earth-shattering, but it certainly is a cost-effective incremental improvement for AGM's with well over 1,000 cycles at 100% DOD.
More importantly to me, a typical 25% average daily DOD translates to 3,500 cycles to get to the operating life of 10 years that I see with Concorde at a slightly lower average DOD. From what I can see, these will sell for about 10% more.
I always have more questions than answers. That's the nature of life.

The 200 ah 6v and 170 ah 8v are in stock in Atlanta and California now.

I tend not to use AGM because of price, but sometimes I do if required.
For offgrid full time homes 220 is just too small even at 48v. One can get an emergency set FLA at costco for about 75 bucks each and this has always been a good back-up until the real battery van shows up.
Is the rumor that the lake went dry true

The storm off the west coast was suppose to suck the hurricane in and rain for us. However, the timing did not work and the hurricane is headed for the islands.
Into our 5th week of smoke. Hopefully the window will open for us before Halloween. Friday!
