Another thing to think about along with larger batteries for the PP is the charging process, which needs to be "shaped" to make best use of the particular battery or batteries, including maximizing battery life.  Also, if the stock PP2000 uses several batteries in series, then each of those smaller batteries is likely to have a lower Ah rating than a single larger battery would.  All this, along with discharge rates and cycles, would need to be considered in modeling a charging system, and the stock charging unit might not be up to dealing with a larger reservoir.

The one thing I take away from all this so far is that it appears that APS have "found" a way to get hi-fi-friendly AC from a battery or batteries.  In and of itself, this is something unique, as far as I know.  It may be that APS' OEM (listed earlier, up the thread) has a range of DC/AC units that are also sonically acceptable for "running hi-fi off batteries"; I just don't know.  In any case, this would still require a suitable charging system, as well, except in this case the charger would not need to be "silent", nor would it need more than nominal AC "conditoning" of incoming AC.
