    I am trying to redesign a couple hundred watt load off-grid system
    by first focusing on the battery technology.  The Li based battery
    "packages" I am aware of are essentially for a residence, which is
    too large for this application. Can you recommend a manufacturer of
    Li batteries that can be used in an off grid application that had
    safe battery charging capabilities as part of its product line. 
    Currently, 2 Trojan L16s are being used, which, while is a fine
    battery, is limited in its depth of discharge.  Thanks for any
    info/help.  Chris
