Designing a bettery Battery Cable and What NOT to do
The pre-manufactured 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 cable 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.
In contrast, notice the custom-cut cable below.
As already stated, the Brass connectors.discovery solved corrosion issues.
But now it's time to consider improving upon another existing "cookie-cutter" convention.
Cutting tailored cable lengths allowed for reduced costs in cabling,
reduced phantom energy loss,
and allowed for 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.
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.
Keep the Baking Soda near each battery bank just in case something should arise.
Now I'm going to interject and place What NOT to Do here.
We interupt this webpage to tell you about something really stupid.
Not too many weeks ago I had this great idea to experiment with two of the best battery banks. Each had responded differently to the test, more-than-likely due to each battery-bank possessing different quality batteries (Duracell knock-offs vs Trojan).
Before I tell you about the test let me first tell you that the battery banks were almost too perfect, certainly the best two that are located in this building.
Being slightly retarded I decided to experiment with them.
It cannot be expressed how much you should NOT do this. When something is perfect, walk away and stay out of the mix!
Yawn. So waking up and feeling experimental (emphasis on mental), I decided it would be a great day to raise the voltages to the two battery banks to see their effects.
That in-of-itself is not a bad thing if they were stray batteries are rated for the voltages increase. And in all honesty, I Know Better!It's probably always better to remain lower than the capitalist's specifications anyway (it's been my experience that it's more likely that the manufacturers and sellers of the available products here in the U.S. are generally over-rated and propagate a lot of hype to make sales go up).
So the setup was that each of the battery banks WERE set to absorption rate of 14.40 volts with an absorption time of 180 minutes before settling into the float stage of 13.70 volts.
Along comes me and now the absorption rate was increased to 14.70 volts before settling into a float stage of 13.50 volts
What was the effect?
The batteries are probably totally fine (basically I gave them an extended equalize state is all), but the water levels went down due to boiling at the higher charge rate.
This was no big deal. Where I ordinarily need to water the batteries once every 3 or so months now came an unexpected need for distilled water (and I don't drive).
My mom brought 3 gallons but that didn't even cover 3 of the 22 batteries affected. So, I fired up the wood-burner and began making distilled water. As the water levels were brought up I couldn't help but to notice there was an unusual oily substance over the tops of the one battery bank that is not of great quality (Duracell knock-offs).
The oily substance made the batteries look older than they were. Each battery comes with a total of 4 terminals (as opposed to an automotive battery that possesses only two)and it was surprising to find that primarily the affected terminals were not even those that were being used at all. They had a strange evil color of sulfation build-up around them. This NEVER happens so in trouble-shooting (because I totally forgot about the experiment after having changed the voltages in the fist place), I went in the other direction.
I checked the loads, wasted time. I checked the orienation to the now-fall sun, they were all needeing adjusting. If the reader of this wonders what I'm talking about, then you invariably live in a southerly State (I'm in Springfield Ohio where the sun is all over the place).
Eventually I checked dip-switches and noticed the outrageous settings.
Well one good idea deserves another and there I went with great idea $2.
I'll have to stop back here and finish this later....it's just too depressing right now to finish.
More of this?
