There was the TougherUPS, UPS Watchman, Dell Transformer, etc...
And now... The Symmetra LX Monster
This unit is made with an APC Large Battery cabinet containing twenty C&D Dynasty 93ah batteries for over 23,000vah of battery umph!
Its equal to about (3) APC Symmetra SYARMXR9B9 battery cabinets at 60% off the new APC price. Plus its still $2000 less than buying 3 refurbished SYARMXR9B9.
The secret is the high rate high amp batteries. Not only are they cheaper per battery watt.. they last twice as long.
Our original Demo unit has come back to us and its $1000 off our normal price.
