<p>Simpliphi is another Li+ that is very much worth looking at too.
It comes in nominal voltages that are usable (unlike Tesla) such
as 12 v, 24v, and 48 v. It is also rated to 10,000 cycles to 80%
DOD, which actually could outlast the rest of the system. It is
Lithium Iron phosphate which is heavier than the Tesla, but not
prone to thermal runaway. I haven't tried them yet, so I'm just
in study mode. The voltage stability as the battery discharges is
very attractive. Even at high discharge rates, it holds above
nominal voltage to 90% DOD.</p>
<p>My problem is I have not been able to figure out how much we can
under size these relative to their lead acid counterparts. Being
that they have better capacity at high discharge rates, are less
temperature sensitive, can't freeze, and can be discharged 100%,
I'm guessing we can downsize them by about half, but I think it
would really depend on the application. <br>
Anyone that is using Li+ (like Larry Crutcher) want to chime in on
sizing of Li+ battery banks compared to lead acid? Downsizing is
the only way we could possibly start making these affordable.<br>

I hesitate to bring this up, but I’ve had some questions
come my way about the “new” Tesla 2.0<br>
battery backup units. And with the demise of Aquion, looks
like Lithium and LA are pretty much the only games in town.<br>
<br>
I have been able to find quite little on line ( surprise),
pretty much nothing from Tesla directly, but some from other
folks by google search.<br>
<br>
Does anyone on the list here know anything solid?<br>
For example.<br>
what inverter is being used?<br>
how do they stack?<br>
battery chemistry?<br>
actual size ( depending on which info it changes)<br>
are they actually shipping?<br>
<br>
<br>
Thanks<br>
