RE: Christopher Zach (ET) 36 volt inverter from Tripp-Lite

I price models that were specifically charger/inverters.  An extra $20 and 
worth the difference.

Be sure to check with the manufacturer first.

Back in the days when Statpower built their chargers in Canada (they are 
now 
importing them from the Chinese sweatshops), I was considering them for a 
road EV, so I asked about this.  They told me that the outputs of their 
double chargers were not isolated, so they can't be used to charge 
batteries 
that are connected in series.  (A friend of mine who's looked at them 
since 
they outsourced the production says the build quality has gone way down 
anyway.)

Other brands may differ.  I believe that the Guest chargers ~can~ do this. 
 
However, several road EV owners tried them a few years back, and found 
them 
unreliable, so tread cautiously.

I have no information on any other brands than Statpower and Guest.
