Andy on the offgrid garage youtube channel actually just did that a few days ago. his summary was most of these LFP cells will degrade faster due to calendar aging than solar usage will

An 18S pack of 280 cells would be over 16kWh… 3.4 float is nigh 100% soc, so, it should be a HUGE bank…

I don’t see a downside to using 18S, keeping the pack in the knee will dramatically extend their life, as long as you do not discharge below 2.5V per cell… maybe someone can do the math and see what the best lifespan and energy density would be… 3.0 to 3.5 power range… heck, 2.8 to 3.4 would be nearly a full cycle, and a lot of Wh’s….

I put a Victron Smart shunt on the battery.
It has registered 8 cycles since limiting my batteries to between the legs, installed October 20221.
