<p>I'm sure Storm Power Components would have done an excellent job
of fabbing what we needed but we didn't have the time to work
through their lengthy design/quote/build process. So the bus bars
we used were purchased from Mcmaster-Carr
<a class="moz-txt-link-freetext" href="https://www.mcmaster.com/products/bus-bars/">https://www.mcmaster.com/products/bus-bars/</a> they arrived in
two days.<br>
</p>
<p>Bending and drilling the bus bar we used was not that difficult,
though you really need to plan out what you're doing ahead of
time. An advantage of having two rows of batteries is the
amperage in and out at the paired 4/0 connections immediately gets
halved.<br>

I sent a diagram of my proposed arrangement
and bus sizes to SimpliPhi prior to installation, which
they approved. The buses (copper 11000) running across
the terminals are 1 1/2" X 3/16", they have a rating of
480 amps. The "bridge" buses are 2" X 3/16" with a
rating of 610 amps. The greatest possible
charge-discharge on this pack will be ~327 amps which is
only 16 amps per battery. Typically the max supply is
11.5 amps, loads are less (1, 8048 Radian). The inverter
cables are pairs ( +& -) of 4/0. Picture attached.<br

rise in temp with these amperages. The reasoning was the
amps moving to each battery is so small that even though
the batteries at the ends of the buses have more bus to
move through, they are so over-sized that there would be
a negligible difference in voltage, small enough for the
BMS to handle.<br class="">

I guess the answer to your question is send
your proposal to the battery manufacturer, there are
charts all over the internet for bus ampacities. The
final touch on the way for this installation is a full
sheet of plexiglass mounted on the front of the pack
with multiple stand-offs. BTW, the structural is #1, 4 X
6" doug fir, its a 76 Kwhr pack to 100% DOD. We do a lot
of car charging around here.<br class="">
