    <p>Hello Wrenches, 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</p>
