The UPS w/ external battery is a great idea. One thing you need to watch however is the in-rush current of a nearly drained battery stack. If there was an outage which took the batteries down to where the UPS shut off, when A/C returned the batteries *might* want allot more food than the UPS's charger can supply.
Restated, an array of large GelCels or Edisons capable of 200 Ah delivery will toast a 200 VA Triplite's internal charger. Trust me - there's a reason big battery arrays have large chargers. --- In [email protected], [EMAIL PROTECTED] wrote: > Just to add to Russ, W3CH. > The local club in NJ that did > this did NOT install the battery's > in the UPS.
