Tip #2 Design your own Cable
Making your own cabling is a pain in the asz.
You won't be accomplishing this with a pair of scissors, so break out your
sharpest blade, grinder, or precision cutoff saw; and after having chopped
the connectors specified in Tip
, clean off both ends, carry the wire to the battery bank, and get
a measurement leaving a slight allowance for movement on the parallel
connections (none for the series connections).
Be careful while assessing your cut.
It's true, 12v electricity is eons
safer than the grid electricity, however handling batteries unsafely can
hurt or kill you. I would include here an actual occurrence but I fear
the departments that are set over us as they would use my words against
my freedoms to use the time given by God in the manner in which I
choose. This is the most nefarious of censorship as it hinders my being
able to translate an actual heads-up to the citizenry here.
One cut for your SERIES connection and one for your PARALLEL.
A.) When cutting for series connections, make the cables as short and
direct as possible. These connections are generally clear from the service
cell caps, having play in the series connection would be of no practical
use, that I can think of.
B.) When cutting for parallel connections, make the cables from the first
connector, T H R O U G H
to the farthest battery connector that your cable will reach. Less cuts
equates to less energy loss and minimizes other potentially detrimental
variables. Using a sharp knife, cut wherever the other connectors may be
located. Seen below are cables that extend from& the first terminal to
the third terminal (WITHOUT A CUT). In other words the cable is continuous
through the second terminal.
The argument for custom-cut cables isn't just an argument for safety's
sake, or that it looks neater, or that the result are a more-efficient
battery bank, but also you are gaining the least cost per lifetime by
making your own cables.
In our present-day economically controlled societies, the pre-manufactured
crappy cables are all cut one-size-fits-all (basically), which leads to
critical problems. Anyone having to check the specific gravity of each
cell in each battery, or adding distilled water or sulfuric acid to each
cell in each battery, has encountered the tangled web the corporate crap
creates. Cables are strewn seemingly everywhere no matter how well you try
to loom them. The mess of cables causes confusion, is a proponent of
potential accidents, causes phantom energy loss due to unnecessary
length/distance, and simply looks bad.
Now notice the nice, neat, predictable cables you see in the photo shown
* DISREGARD the DUST (I call it oil-sop)
Aside from the evident fact that I don't generally bother dusting the
batteries (as opposed to the uncensored portion of the Internet which
typically depict batteries that are shiny and probably just for show,
financed by the very entity seeking to gain advantage), more importantly
notice that there isn't any acid build-up around the posts and connectors.
It is patently impossible to clean the posts without disturbing the dust
around the posts...so that's the excuse, I'm just waiting for the day when
I have to clean the posts!
Brass connectors solved corrosion issue
Cutting tailored cable lengths allowed for reduced costs in cabling,
less phantom energy loss, and a safer/more predictable work space.
Direct cable connections from one terminal to the next allows for
quicker transference of power with least amount of heat loss (resistance
due to excess cable length), and overshadows the problems caused by
excess cable, whether it be at the battery bank or the distance from the
battery bank to the end-user device, hub, or appliance.
So if the common marketplace only offers one size in battery cable
thickness, and only offer one or two lengths, cutting it all down for
tailored cuts meant nothing gets wasted. If the next generation want
thicker cables, let them finance it, these cables are getting recycled
is the primary battery bank that handles some of the larger loads such as
washer/spinner, freezer, bread-maker, blender, etc. However it is
needed to be increased due to no-sun season (winter).
a spare Battery Bank is available to increase the capacity/longevity of
the 48v Bank.

Since I converted all cabling to brass connectors, this shows the cables
after a year or more of use.
When it is opportune, checking specific gravity within the battery cells
is a great way to see the true health of a battery.
At times a few drops of the battery acid may spill.
Take no chances with battery acid. Neutralize any spills with
plenty of ...
This stuff is acid neutralizer.
