The other current big issue with the Lithium batteries at this time is the inability to ship them via any common carrier.
I am driving to AM Solar from Phoenix to pick up the new 12Vdc 600 amp hour unit next week and bring it back home. At the end of the month, the battery and our rig will go to have this conversion done along with installation of an instant on water heater and a few other "tweaks".
