Per
this paper, if you look at graph
d, there isn't much difference between 20, 60 and 100% depth cycles. You still have 90% initial capacity after 3,000 cycles.
253 miles x 3,000 cycles = 759,000 miles on odometer. 786,000 if we use 262 miles per charge. This battery will go past a million miles.
My normal use is 100% -> 30-40% before I recharge so my cycle depth is actually 60-70%.
The beauty of LFP is the usefulness of the top end of state of charge (SOC), durability when dipping into lower SOC and reliability of power until 5% SOC -- when voltage starts to tank.
