What is the difference between 5 batteries and 6 batteries?

Here are the differences between 5 batteries and 6 batteries: 1. Different battery voltage: A 6-battery setup is a 72v20ah battery pack consisting of 6 12v20ah batteries connected in series, while a 5-battery setup is a 60v20ah battery pack consisting of 5 12v20ah batteries connected in series, where 20ah refers to the battery capacity. 2. Different battery capacities result in different ranges: Clearly, the 72v20ah setup has the capacity of one more battery than the 60v20ah setup, so under the same conditions, a 72v electric vehicle will have a longer range. 3. Different speeds, higher voltage means faster speed: With the same motor, higher voltage results in higher rotational speed, meaning a 72v setup is faster than a 60v setup. This is often referred to as boosting voltage to increase speed. Modifying electric vehicles usually involves adding batteries to increase voltage for the purpose of speed enhancement, provided that the motor can handle it.

I personally think battery voltage is quite crucial, especially in older cars. 5-volt batteries are virtually unseen in automobiles—likely a misunderstanding or meant for small gadgets. But in the vintage car scene, 6-volt systems remain quite popular, like in classic Beetles. The difference lies in voltage: a 1-volt gap between 5V and 6V may sound minor, but it profoundly impacts cold starts. A 6V system delivers weaker power, resulting in sluggish winter cranking and dimmer bulbs, whereas modern cars universally use 12V (equivalent to six cells) for steadier performance. Installing a 5V battery in a vintage car would fail to start the engine and might fry components. Upgrading to 12V boosts performance but requires replacing the alternator and wiring at significant cost. Overall, 6V suits classic cars preserving originality, while 5V is a misguided concept with zero practicality.

As a long-time car enthusiast, I've studied various electrical system configurations. '5 batteries' might refer to the number of battery cells, but standard automotive batteries have about 2 volts per cell - 5 cells would make 10 volts, which is rare in reality; 6 cells form the standard 12-volt system. 6-volt systems were common in pre-1950s vehicles like some classic Ford models - while lower voltage meant simpler construction, the downside was cable overheating during high current demand. Modern 12-volt systems are more efficient with better accessory compatibility. The key differences lie in voltage and application: 6-volt suits nostalgic restorations, while 5-cell (10-volt) configurations have virtually no practical use except for special modifications. I recommend vintage car owners either maintain original systems or convert to 12-volt, avoiding mixed configurations that could cause issues.

I've experienced the era of old cars with 6-volt batteries, which had many issues. The 5-volt battery is impractical in the automotive world, probably more suited for power banks. The real difference lies in the 6-volt system's low voltage, requiring multiple push-starts in winter and prone to battery aging. The 12-volt system, achieved through a combination of 6 cells, is stable and efficient. The core differences are in performance and applicability: 6-volt is for maintaining antique cars, while the 5-volt concept is misplaced and not suitable for vehicles. Stick to original or upgraded systems to avoid risks.
