Another rally question for the group: what I'm attempting to convey in the chart below (that I'll talk to in the Advanced Solar Seminar at the National Rally) is that 100aH batteries are not all equal. The total usable watts (power available to do work) are not the same. I had to use "guestimates" on some of the LifePO4 voltages so the chart has a consistent % listing.
Note the load is assumed to be a constant 1.5 ohms (resistive) and voltage for a given percentage is constant for 1 hour.
Any input? Please don't hesitate if there's constructive criticism-- I'd rather someone here point out a flaw than find out in front of an audience.

P.S. The rest of the battery section of the Advanced seminar is "stolen" from TucsonJim's presentation (with his permission). Jim's battery slides are in the Reference Material of this channel.
