It seems the information is copied from the A123 data

LMAO !!!
With few years with TS LFP cells and always charging to 4,3 V has very
little effect on the lifetime. Thou... I will post here some data by the
end of this week about the cycle test on LFP-30 cell.
I have several vehicles with LFPs on the roads. The cells do not give
out the name plate capacity unless you take it to the 4,3 V. Charging is
stopped when the current is less than few amps.
The voltage drops quite fast down to 3-3,2 V in driving. But stays there
until about 20% SOC. then it drops nicely to 2,7 V. Stays there for a
while.. and then drops like a rock to 2V.
This is how LFP-350 cells behave.
They give 100% DOD cycles out (from 2V to 4,3V) over 1000. In my case I
can expect at least 700 000 km (430 000 miles) on the Bus batteries
(before less than 60% 0f original capacity).

I rarely drive more than
100 km a day with the bus "green moster" (
http://www.austinev.org/evalbum/1009 ).
TS cells are MUCH different from A123s. Tolerances and purities are WAY
different. A123 guys, try to make your cells with purufied tab water.
If you'd know how cheap they are to make you would S#
[email protected] your pants !
Thou A123s can out perform the TS in power, cyclic life and capacity. TS
beats with the price.
Thou.. I STILL like more LiCo cells... I need energy dense batteries...
