   I've seen advertised in some table of models, that there   
   was a model for Japan that used lithium for power storage.   
   It wouldn't be LiFePo because that would double the volume   
   of the unit. Other than solar powered garden lanterns,   
   there isn't a lot of the "nice and safe" LiFePo in high   
   power devices. They'd probably prefer SLA instead of   
   LiFePo.
