Why would I need a relay between a DC motor and my Arduino?

A motor connected to a relay will generate electricity when the relay opens. The voltage produced by the motor will rise quickly, and could even cause an ''arc'', or spark. The motors generated voltage is usually conducted away to avoid this effect using a diode.

Wiring Batteries in Parallel Danger: A Comprehensive Safety Guide

In a real-world scenario, if you connect a 100Ah new battery with an 80Ah older one, the older battery will reach its capacity faster, forcing the newer one to overcompensate. State of Charge: A battery at 90% charge connected to one at 50% can cause rapid discharge rates, akin to a car moving downhill without brakes.
