The gauge of a cable refers to its thickness, with a smaller number indicating a thicker cable. The thicker the cable, the more current it can safely carry without overheating.
There are plenty of charts associated with all things batteries and solar. You can use a high or low-voltage wire gauge chart to see the amount of current flowing through or the size of your cable. The battery cable size chart is a good way to see the effects of changing a cable size as well as deciding whether you need an upgrade.
Remember that choosing the correct wire gauge for your battery cable size is based on two factors: current and distance. Now that you know how to calculate your current requirement, you just need to figure out how far you need to run your cables. Remember, shorter is always better. Less cable means less weight and lower cost.
A battery cable gauge chart is a useful tool for selecting the right cable size based on your system's amperage and distance requirements. This chart helps you visually correlate the amperage your system needs with the appropriate cable gauge. It's especially helpful for avoiding the guesswork involved in choosing a suitable cable size.

It is easy to tell from the above diagram that battery cables typically have larger sizes due to the high currents they are designed to carry, and you may notice that whether it is solar battery cable size or marine battery cable size, they are generally thicker than other types of wire.
Many boaters use the word “voltage” without really understanding what it is. Voltage is not current, that is, it is not the movement of electrons from one point to another. Rather, it is your boat's electrical system's ability to move electric charge from one point to another. Think of it as a hose pipe – the water that flows. Below are easy steps on how to hook up a boat voltmeter to ensure that your battery is in tip-top performance. Now that you are done with your boat voltmeter wiring, how do you take a reading? Well, some boaters prefer keeping a constant check on their meters when the boat engine is running while others prefer taking their reading when every accessory is.
For example, vehicle batteries. Here is a simple Battery Monitor circuit for a brisk check of a 12volt Lead-Acid Battery. The circuit fabricates with the help of the LM3914 and a few other components with 10 LEDs which will indicate the voltage level. Battery charge should be continually observed to monitor the life of the battery.
The terminal voltage of the Lead-Acid battery should be within a certain range such as 12 to 13Volt. In the event that the battery voltage lessens beneath 10 volts for a long period, the battery won't accept any charging current. Thus, if the terminal voltage surpasses over 14 volts, the battery will be devastated.
There are two ways to wire batteries together, parallel and series. The illustrations below show how these set wiring variations can produce different voltage and amp hour outputs. In the graphics we've used sealed lead acid batteries but the concepts of how units are connected is true of all battery types.
A couple of hardware needs for adjusting the circuit for a 12volt battery. One is the lab power supply and the second is a digital voltmeter.
