[RE-wrenches] Lithium Ion Batteries

[frenergy]

Wrenchers,

             I seem to continue to have my foot stuck in the past 
regarding off-grid.  Off -grid seems to have more of an element of a 
need for reliability, redundancy, klugability.  Believe me L-ion 
batteries and especially the "total units" like the:

are beautiful answers to "buy it connect up the cables and forget it", 
no maintenance to boot.  I want one. But Yikes, many of these companies 
are new, which will survive well into their warranty period?  Its a 
double-edge sword....if we don't transition into the L-ion world, how 
will they survive?

             Also, if the charge controller, battery cell (in 2 volt 
cell battery pack), fan or inverter fails in a more conventional system, 
there's probably a go-around spare whatever in stock (or the failed 2 
volt cell can be cabled around waiting for a new cell).  Maybe all I'm 
asking is how field serviceable is a failed L-ion battery or its BMS? or 
the total units like above? Are there failures? maybe too soon to know.

             Go ahead, beat me with a stick, maybe I'll learn something.
