How many volts should a fully charged 36 volt golf cart have?

Answered by Willie Powers

To determine the voltage of a fully charged 36 volt golf cart, it is important to understand a few key concepts. First, it is common for batteries to read slightly higher voltage when fully charged than their nominal voltage rating. This is due to factors such as internal resistance and self-discharge. In the case of a 36 volt battery pack, it is not uncommon for it to read around 38.2 volts when fully charged.

However, it is worth noting that the voltage reading can vary depending on the specific battery chemistry and the charging method used. Different types of batteries, such as lead-acid or lithium-ion, may have slightly different voltage characteristics. Additionally, the charging method, whether it is a traditional charger or a smart charger, can affect the voltage reading as well.

Now, when it comes to the maximum drop in voltage under load, it is generally recommended that the voltage should not drop too low to ensure optimal performance and longevity of the battery pack. As a general guideline, a maximum drop of around 6 volts below the fully charged voltage is often considered acceptable.

In the case of our 36 volt battery pack, if we consider a fully charged voltage of 38.2 volts, the maximum drop under load should not exceed 32 volts (38.2 volts – 6 volts). This means that the voltage should not drop below 32 volts or less when the battery pack is under load.

It is important to note that exceeding the maximum drop under load can result in decreased performance and potentially lead to premature battery failure. Therefore, it is crucial to monitor the voltage levels of the battery pack regularly, especially under load conditions.

A fully charged 36 volt golf cart battery pack may read around 38.2 volts. However, it is important to ensure that the voltage does not drop below a certain threshold, such as 32 volts or less, under load conditions to maintain optimal performance and longevity of the battery pack. Remember to consult the manufacturer’s guidelines and recommendations for your specific battery pack to ensure proper voltage management.
