Designing a bettery Battery Cable

and What NOT to do

Off-Grid Battery Power

Tip #2 (part 2)

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 sulphuric 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 cables. The connections to the cables are easy to identify, inspect, and work around.

As already stated, the Brass connectors discovery solved corrosion issues and other common problematic issues intrinsic with contact of two metals made possible by the connectors, long-term placement of cables might best follow suit.

Tailor-cut cable lengths allow for reduced costs in cabling, reduced phantom energy loss, allows for a safer, more predictable work space, etc.




The Complexities of Series Connections within a Bank of Batteries

Pertaining to a solitary 12v battery, there is little to consider since it requires no series connections for cables because the series connections are contained already within the solitary battery via cells.

Those cells intrinsic in the solitary 12v battery are all equal dimensions, a uniformity which can be equalized moreso than six 2v batteries in series via cabling.

However if the same 12v battery were comprised with six 2v batteries, long-term consideration of the quality and placement of the series connection cables are a variable worthy of prioritization.

Consider the effect where each cable that connects from one battery to the next are all different sizes and lengths, what would be the effect?

Thinner cabling would carry the heat, longer cables will carry the heat, both will become vulnerable to a short-circuit.

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.


If you can afford it, the closest cable to "0" is where you want to be (remembering that the series cuts generally do not require any excess play for movement once placed).




Hydrometer is a must for battery bank maintenance

Baking Soda Neutralizer

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 Baking Soda


Keep the Baking Soda near each battery bank just in case something should arise.
