If you have one or two cables that are longer than other cables, it will change the resistance within the battery pack. Maintain the same length of the wiring between the batteries. Good wiring practice also means putting down the fuse in the anode side. Remember, by connecting lithium batteries in parallel, you can keep the nominal voltage at 12 v, but it will increase the Ahr capacity, so the discharge and charging will be higher.

This is called connecting the lithium batteries in parallel.

Lithium batteries can be connected to generate more energy to run larger motors or extra capacity. Can we have a battery that can give me more voltage or current? The answer is yes.
