Do yourself a favor, and switch to watts. That way you don't have to
worry about how you string your batteries together, because watts is watts.
For example, if you have a 100 amp-hour battery at 12 volts, that is
1200 watt-hours. If you have 27 of them (again for example), you don't
have to worry about series/parallel issues because 27*1200 watt-hours is
the same regardless.
Your 109 watts sounds high to me. What do each of the ePTP consume? Our
PMP450 APs are typically using about 12 watts (I think they are rated
more like 15 watts). I think an RB2011 is probably only about 6 or 8 watts.

This is a new concept for me. We are in the process of planning and
deploying three new sites. Like a lot in the WISP world they are
remote. I was wondering if you guys can point me at resources to
start educating myself on this process and put together some numbers
for cost. The sites themselves are fairly simple. The largest will be
running three Eptp Force 110 backhauls. Two Epmp APs and two
Cambium450�s. Microtik 2011 for the router / switch. Using GigSync
Injectorts for the GPS and power. The other two sites are the same
but only one backhaul. Being way up north the calculations I am using
are for Duluth MN weather which should be fine.
I am coming up with 109 watts for this main tower according to google
and manufacture spec sheets (seems like a lot) . Where I get into
trouble is when I start to try and calculate Ah. Any good websites /
youtubes that will help me get a grasp on this?
