Making your own cabling is critical
a pain in
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 #1, 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.
true, 12v electricity is eons safer than the grid electricity,
however handling batteries unsafely can hurt or kill you.
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 clear from the service cell caps,
having play in the series connection would be of no good use, that I
can think of. These particular series
connections require no allowance for play.
B.) When cutting for parallel
connections, make the cables go 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. Seen below
are cables that extend from 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 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
Now notice the nice, neat, predictable cables you see in the photos
* DISREGARD the DUST (I
call it oil-sop)
Aside from the evident fact that I don't generally bother dusting
the batteries ever (as opposed to the uncensored Internet typically
depicting 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
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
Brass connectors solved corrosion issue
Cutting tailored cable lengths allowed for reduced costs in
cabling, less phantom energy loss, and a safer/more predictable
Direct cable connection 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,
So if the common marketplace only offers one size in
battery cable thickness, and only 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 as-is ';-)).
