Oldsmoky,
I disagree with some of the statements. In particular, the high rate on LI. c1 is possible but not recommended.
Not all LI jars are made to "play together well", in fact some companies flat out say "don't do it".
The other rub about LI is their cold weather charging problem. I'd never be able to use them.
If the wiring is balanced (which it should be) then lead acid jars can be placed in parallel successfully. By successfully I mean getting 9 years of service.
A few of us are using telecom jars. It certainly beats laying down in the snow to check electrolyte levels. It is too soon to say if cycle life will be an issue, but I'm at about 18 months so far. These are "take outs" from cell towers, so they were not brand new. The price was right.
C rates in testing are often 25 amps. So with large inverters the cell count becomes a factor.
My ultimate battery bank would be 800 to 1000 amp-hour 2 volt Surrette jars in a
48 volt bank. Alas, I'll never be able to afford such a lovely system.
