According to Purkeys Fleet electric, optimal cable choices will lead to exceptional electrical performance for your fleet. Here’s why you should be concerned about the cables that connect the parallel batteries in multiple battery systems:

• Cables are a critical component in cranking and charging as they provide the path for current to flow to and from each battery. Here are three key elements to look out for with your cable installation:

1. Length: They must be long enough to have some flex and comfortably reach each battery.They should not be too long that they route over the batteries or touch other cables.

2. Flexible: The cables must be very flexible so that they absorb vibration and do not induce stress on the terminals.

3. Correct gauge: Larger gauge cables provide more current-carrying capacity and reduced voltage drop.
In addition to choosing the right cable length, flexibility and gauge, terminal ends must be sealed and they need to be tin-plated copper lugs with correct hole sizing. Here are a couple of important features of terminal ends:

Plated terminal ends: Tin plating over copper provides great conductivity while offering the best corrosion protection.

Heat shrink: Heat shrink is designed to seal the terminal to the cable and not allow corrosion to wick up the cable.
