Reads like marketing fluff. I'd agree if it said 500-1000, but not 3000. I'd agree with 3000 at maybe 50-70% DoD. Now, many batteries come with much more energy than their nameplate, and since they have a bms in there, they can play in a narrower range of SOC - effectively self derating. If that's the case 3000 is more plausible.

" Of note: Draining a new 100AH LiFePO4 battery down 100% is not completely draining the cells. They generally have significant excess capacity until about 2500 cycles.

Of course we are looking at it. Very cool project, BTW.
