Another Lithium Ion batteries question
Could these batteries which are for ELectric vehicles be also used in an RV for deep cycle purposes? http://www.evwest.com/catalog/index.php?cPath=4&osCsid=naglhlcs4afl705sfec49hln20

We think you really should use monitors if you go to LFP. I know a few folks whose opinion I value on various fora who disagree but automating as much as possible makes life simpler. We have the following:
TriStar Monitor: power rate in watts (or night), voltage of battery bank, watts "harvested" that day, state of battery charge (absorb, float)
Manzanita Micro monitor: voltage of battery bank, voltage of each individual cell (16), watt-hours from full charge
Magnum inverter monitor - can check all kinds of things of which I am ignorant and should read up some day.
Of importance is voltage of the cells. 3.4 V is float and which many (who do not like using BMS) set their system. 3.6 is maximum the cells should reach and our BMS controls system to stop at 3.6 V and go to float. Many believe that severe damage occurs above 3.6 V (cells will go to 3.9 V). 3.1 V is where one worries about very fast drop of charge.
