72V 100Ah Golf Cart Lithium Battery

What is the difference between 48V and 72V?

The primary difference between 48V and 72V systems is their voltage output, which affects performance and efficiency. A 72V system typically provides more power, allowing for higher speeds and better performance in applications like electric vehicles. However, it may require more robust components and wiring due to increased voltage.

How many cells does it take to make a 72V battery?

To create a 72V lithium battery, you typically need 20 cells connected in series, assuming each cell has a nominal voltage of 3.6V. This configuration allows the total voltage to reach approximately 72V when fully charged.

What voltage is best for a golf cart?

The best voltage for a golf cart often depends on the intended use. Generally, 48V systems are popular for standard golf carts, providing a good balance of power and efficiency. Higher voltages like 72V are used for performance-oriented carts requiring more speed and range.

What is full charge of a 72V lithium battery?

A fully charged 72V lithium battery typically reaches around 84V, depending on the specific chemistry used. This is based on the standard charging voltage of about 4.2V per cell, multiplied by the number of cells in series (20 cells for 72V).

Can I charge a 72V battery with a 60V charger?

No, you cannot charge a 72V battery with a 60V charger, as it will not provide sufficient voltage to fully charge the battery. Using an appropriate charger designed for 72V systems is essential to ensure proper charging and maintain battery health.

What are the disadvantages of lithium golf cart batteries?

Disadvantages of lithium golf cart batteries include their higher initial cost compared to lead-acid batteries, sensitivity to extreme temperatures, and the need for specialized chargers. Additionally, they may require a Battery Management System (BMS) for safe operation, adding complexity to the setup.

How much does it cost to convert a golf cart to lithium batteries?

Converting a golf cart to lithium batteries typically costs between $1,500 and $4,000, depending on the size of the battery pack and additional components needed, such as chargers and BMS. While the upfront investment is higher, long-term savings on maintenance and replacement can justify the cost.

How fast is 3000W 72V?

A 3000W 72V system can achieve speeds of approximately 25-35 mph, depending on factors like vehicle weight, aerodynamics, and terrain. The formula used to calculate speed involves dividing power by weight and considering efficiency losses in the system.

What is the range of 72V 35Ah?

A 72V 35Ah battery has an energy capacity of approximately 2520 watt-hours (Wh) (calculated as $72\times 35$). The range will depend on the vehicle's efficiency; for example, if consuming 1000W, it could provide about 2.5 hours of runtime or approximately 25 miles, depending on conditions.
