Tip #2 Design your own Cable scheme
You won't likely be accomplishing this with a pair of scissors,
so break out your sharpest blade,
or precision cutoff saw and let's get to work!
After having chopped the connectors specified in Tip #1. clean off both ends and get a measurement leaving a slight allowance for movement on the parallel connections (none for the series connections).
Be careful while assessing your cuts.
It's 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 generally clear from the service cell-caps and having slack in the series connection would be of little practical use.
B.) When cutting for parallel connections, keep the cables as long as possible to catch through as many terminals as possible. Make the cables start from the first connector, T H R O U G H to the farthest battery connector, stripping off the protective jacket to allow for any intermediary terminals that your cable will reach.
Less cuts equates to less energy loss, and minimizes other potentially detrimental variables.
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.
You are also gaining the least cost per lifetime by making your own cables.
The longest cable that could be located here, is long enough to span 3 parallel batteries, another stretch of cable would double-up on the final terminal and resume for yet another unadulterated stretch.
The problem arises when there's only 4 batteries and the cut now is simply jumping one solidly-constructed battery bank, only to have a jump to another 1 or 2 batteries.
If this happens, make sure to always keep the cuts to the back of the battery bank.
In other words, the end that receives the solar or wind-generated power should be connected to the longest continuous stretch of cable at terminal 1, then through terminal 2, then (in my case) terminating at battery terminal 3.
For instance, terminal 3 jumping to terminal 4 could become a hotpoint if the energy coming into the battery bank is located at terminal 4 instead of terminal 1. Terminal 4 in this scenario is the end of the battery bank, which is where any deviation from an otherwise perfect battery bank ought to be placed. By doing so diminishes any possibililty of great heat building up due to shrinking of wire, unnaturally loosening of bolts, and other supernatural occurrences, etc.
As a final note, if you see burned or blackened wire, or greasy wire, these are signs of damage and the cable should not be relied upon. Find another purpose for the damaged cable. The reason you might find burned or blackened wire is due to overcharging or a short or some other problem and a permanent remedy should be sought.
