Why Is My 48v 100ah LifePO4 Golf Cart Battery Pack Too Hot?

Golf cart batteries usually become hot whenever they are used. That is because the batteries are responsible for the large supply of energy to the electric vehicle. It should not really come to you as any surprise when this happens because that is how the battery chemistry has been designed. This heat dissipation and becoming cold again is how it is able to sustain itself over the period of use. 

That said, you need to be weary of your battery getting extremely hot. If you ever sense this or notice some kind of unusual odor coming out from the golf cart battery pack terminals, know that it is time for you to find out why your 48v 100ah LiFePO4 golf cart battery pack is behaving that way.

The level of troubleshooting you will carry out on your cart battery will actually depend on the type of battery you are using and how long you have used it. Your battery will definitely get warm when you are using it. However, if this heat becomes higher than expected, you need to stop and check what the problem is. 

Here are some tips to help you troubleshoot what could be wrong with your 48v 100ah LiFePO4 golf cart battery pack

• It is absolutely necessary you confirm that the battery has been appropriately connected. If the battery has been wrongly connected, it could result to the problem of overheating, forcing the charger to become extremely hot as well. So, something as insignificant as a wrong connection could be responsible for this. Make sure you find this out. 

• Water level shortage – your inability to keep the water in your golf cart battery pack at its required level is an invitation to overheating. Every battery comes with a line that indicates where the minimum water level should be. When that water is always at that level, the possibility of experiencing any overheating will be reduced.

• Air movement – you do not just position your 48v 100ah LiFePO4 golf cart battery pack anyhow. If it is kept in a place where there is poor ventilation, it could start to overheat. Please ensure you connect it in a place where the air flow will be maximum. That way, it can be cooled by the air current, leading to lower chances of any overheating. 

What could make a battery terminal melt?

Battery terminals can melt for a couple of reasons. One of the most common reasons for this occurrence is dirty or loose connections. To ensure this does not happen, there are a few things you could do. Make sure you apply the correct sizes of the wires and try to see that all forms of connections are fastened as much as possible. 

When connections are not tight or even dirty, the outcome is that resistance starts building up on that terminal. You cannot expect your 48v 100ah LiFePO4 golf cart battery pack to perform optimally when it is building up resistance on its terminals. Batteries and resistance are not the best of friends! Resistance will only make the battery heat up more than necessary. 

As you watch out for loose connections to avoid resistance, also ensure you are careful of not making the bolt, nuts, and other connections too tight because that will give rise to wear and tear, and eventually leading to resistance. 

How you tighten your bolts, nuts, and others is what is referred to torqueing. There is a correct amount of torque that you ought to apply when doing your connections. Find out what yours is. 

Why do they become hot as they charge?

It is normal for your golf cart battery pack to be hot as it charges. There is nothing abnormal about it. As electrical energy is distributed from one head to another, some level of warmth should be expected. Having said that, you must be aware that overheating could result from overcharging your 48v 100ah LiFePO4 golf cart battery pack

Generally, you can make use of your battery for virtually an entire day after charging for just a few hours. For some other products, their chargers are designed to go off after charging for over a period of 16hrs. 

The basic thing here is that you keep an eye on the water level of your battery and ensure it does not go below the required level. That will keep your battery in a better state over an extended period.

Why do they smell awful when charging?

If you notice your 48v 100ah LiFePO4 golf cart battery pack releasing an offensive odor whenever it is charging, do not break your head over it. That is the chemistry of the battery, which is how it is designed to behave during charging cycles. Whenever a new battery is purchased, the acid level at that point is extremely high. Hence, it will release some gas when you use it. This is absolutely typical. 

As you continue using the battery in its lifetime, you would keep perceiving this odor though not the way it was when you first bought the battery. The bad smell you perceive during such charging process can be attributed to a product of the charging reaction known as hydrogen sulfide. 

Though the charger might become extremely hot to touch and produces this foul odor, you do not have to be afraid or bothered unnecessarily. The smell and hotness of the golf cart battery pack charger differs from one manufacturer to another. So it does depend on what kind of charger you are using.
