Depending on how you figure li-ion battery voltage (I use 3.7 volts per
cell; I've seen some others say 3.6 volts per cell), it will take 13
li-ion batteries to make 48 volts.
The big issue that I can imagine is that li-ion have a completely
different charging profile from SLA batteries. I don't know whether it
would be better to try to build an array at 48 volts, or go for
something much larger (say 480 volts), and do a DC-DC converter to get
whatever voltage you want on the other side.
This will be an interesting discussion.

Lithium Ion batteries are getting so cheap these days it�s tempting to

they behave well with constant voltage running through them supplied

maintainer with an automatic transfer switch be required?
