Is It Possible To Overcharge A 12v 400ah LiFePO4 Golf Cart Battery?

12v 400ah LiFePO4 golf cart batteries have been a complete revolution in the world of technology. They have proven to be an upgrade of the traditional lead-acid batteries with some modern features and functionalities to meet the varying needs of golf cart owners. According to recent survey carried out amongst people who make use of golf carts, it has been discovered that most people prefer using LiFePO4 batteries in their golf carts. This could be due to their overwhelming benefits which can hardly be experienced with other batteries.

Here is where the problem actually lies

Despite the ever-increasing popularity of 12v 400ah LiFePO4 golf cart batteries, it is important to point out that there are some subject matters which remain very confusing to its users. A typical example such is its charging system. For instance, there are people who believe that these batteries can be overcharged. For this reason, they believe that lithium ion golf cart batteries are a much better option since overcharging them is not possible. 

Are you amongst those who believe that LiFePO4 golf cart batteries can be overcharged? There is no need racking your brains about this subject matter. This is because everything will be revealed about how these batteries have been designed to charge for proper functioning. 

What is overcharging?

It is very important to explain the meaning of overcharging since lots of people are confused about what it truly entails. This is a situation whereby the battery is left to charge even after reaching 100%. It is the point of a battery beyond 100%. Simply put, you must have seen how a lithium ion golf cart battery charges before now. Sometimes, the percentage levels are indicated to help you know when such charging process can be interrupted or stopped. 

A situation whereby you leave the battery to keep on charging after attaining 100%, such is referred to as overcharging. It has some serious implications on the battery power which most people do not know. For instance, overcharging has the same effects as over-discharge in a LiFePO4 golf cart battery. This is one of the major problems that shortens the lifespan of most batteries. 

When a battery is constantly overcharged, there is every tendency that its power will be reducing gradually. The same thing can also be said when it is over-discharging. This also reduces its storage capacity to a great extent. For instance, a battery that is meant to last for 72hours can stay for 68hours due overcharging or over-discharging. Over-discharging is a situation whereby the battery power is allowed to drain up to zero percentage before a charging process can be initiated.  

Key points to note:

• Overcharging means charging beyond 100%

• Overcharging can kill a LiFePO4 golf cart battery

• Over discharge can kill a LiFePO4 golf cart battery

Is it possible for a 12v 400ah LiFePO4 golf cart battery to overcharge?

The first thing you have to note about these batteries is the fact that they have been built in a special way. Simply put, they cannot be overcharged. In other words, they can hardly be overcharged. For instance, they usually come with battery management system (also known as BMS). This component is responsible for protecting your LiFePO4 golf cart battery against over-current, short-circuiting, over charging and over-discharging. It is through the Battery Management System that the charging condition of these batteries are monitored. 

It is like a detector which works round the clock to ensure your LiFePO4 golf cart battery is in a very perfect condition. This is done through monitoring the charging state and cutting off current supply whenever such is necessary. It should be noted that lithium ion golf cart batteries, regardless of their capacities, also have this component in place. Without its installation, your battery will experience excessive charging thereby reducing its power over the course of time. This can make you to spend unnecessarily. 

Key points to note 

• LiFePO4 golf cart batteries come with in-built Battery Management System which prevent them from being overcharged

• Lithium ion golf cart batteries also have similar BMS features 

• Without BMS, a battery will have shorter lifespan

What can go wrong?

Just as said above, a LiFePO4 golf cart battery has BMS (battery management system) which helps to prevent any problem related to overcharging. However, such does not imply something cannot go wrong. For instance, if the battery management system is not doing a proper job of preventing overcharge, there is every chance that your battery could be vulnerable to being damaged. Although cases like these are very rare, they can happen especially when your battery has been used for a long period of time and the internal components have started experiencing wear and tear factors.  

At such point, there are certain things you can do to ensure your battery does not get affected by overcharge or over-discharging problems. Some of these will be listed out below. 

Using a timer. This is probably one of the most effective ways to avoid the problem of overcharging once your BMS is not functioning as expected again. You can use a timer to ensure the battery does not charge beyond a particular number of minutes or hours. All you have to do is set the timer and monitor it regularly to know whether the charging process will be disconnected. 

Avoid 100% charging. Charging a 12v 400ah LiFePO4 golf cart battery up to 100% is very risky especially when the BMS is no longer active. This is because its power will be reducing gradually since there is no monitoring or protective system in place. This is probably one of the major reasons why most batteries stay up to 3years and get damaged. If your BMS is damaged, it is recommended that you do not charge a battery up to 100%.

Having seen the above, it is obvious that a LiFePO4 golf cart battery cannot be overcharged due to its BMS. However, there are instances whereby it can experience such problem. One of such is when the BMS is damaged or dysfunctional.
