Types of 36V battery for golf cart

Lithium batteries

Ordinary lithium batteries are divided into NCM lithium batteries and LiFePO4 lithium batteries, while the lithium 36V battery for golf cart generally are LiFePO4 lithium batteries.

A lithium iron phosphate battery (often abbreviated by its chemical composition LiFePO4 battery; or further abbreviated as an LFP battery, which stands for Lithium Iron Phosphate) is a lithium-ion battery whose positive electrode material is made of Lithium Iron Phosphate.

LiFePO4 offers many advantages over other Li-ion battery designs and older lead-acid (LA) batteries. They are lighter, require zero maintenance, have better charging and discharging characteristics, and last longer, making them one of the most valuable electric propulsion solutions in the golf cart segment.

Other key advantages of LiFePO4 include high current ratings, longer cycle life, zero leakage and fire risk, and resistance to suboptimal charge and discharge cycles.

Lead-acid batteries

Lead-acid batteries are by far the most popular and used rechargeable batteries. For over a century, they have been used in a wide variety of applications including golf carts, RVs, energy storage, emergency power sources, electric vehicles (even hybrids), communication systems, emergency lighting systems, and more.

The widespread use of lead-acid batteries is due to their wide voltage range, different shapes and sizes, low cost, and relatively easy maintenance. Compared to other secondary battery technologies, lead-acid batteries are the cheapest option for any application and have relatively stable performance.

However, with the development of technology, lead-acid batteries have been abandoned by many countries due to high pollution and low cycle times, and they have turned to the development of lithium battery technology—LiFePO4 lithium batteriesare environmentally friendly and have a lifespan of up to 10 years.

Lead acid battery vs lithium battery, Which is the best 36v battery for golf cart?

Lead-acid batteries have a long history. After hundreds of years of development, lead-acid batteries have a lower upfront cost, but a short service life and require regular maintenance to maintain normal operation. In recent years, lithium batteries have sprung up and occupied more shares. The initial price of lithium batteries is much more expensive, but they are maintenance-free and have longer service life and higher efficiency.

Compared with lead-acid batteries, lithium batteries have the following advantages

  1. Environmentally Friendly
  2. Lightweight And Compact
  3. High Energy Density
  4. Low Maintenance
  5. Long Lifespan
  6. Low Self-discharge Rate

In terms of user experience, obviously lithium batteries are the best batteries for golf cart.

How To Install A 36v battery for golf cart?

There are two ways to install a 36v battery for golf cart. You can use a single 36V LiFePO4 batteries or three 12V LiFePO4 batteries. Both methods is fine, and each method has different installation requirements and advantages.

If you’re not good at wiring the battery by yourself, you should consider hiring a professional.

36V LiFePO4 batteries In Parallel

Connecting a 36V battery is relatively simple, Just as below picture.

First, connect the positive (red) terminal of the 36V battery to the positive (red) lead on the motor. Then connect the negative (black) terminal to the negative (black) lead on the engine. That’s it. Your installation is complete.

12V LiFePO4 battery In Series

Firstly, using the connector cable, connect the negative (black) terminal of the first battery to the positive (red) terminal of the second battery. Then do the same thing to connect the second and third batteries.

At this point, you will have three 12V batteries.

Connect the positive (red) terminal of the first battery to the positive (red) lead on the motor. Then, connect the negative (black) terminal of the third battery to the negative (black) motor lead.

If you have successfully connected all three batteries, your 36V LiFePO4 Battery system should be ready to use.

As a bonus, you can install a power switch on the positive lead. This way, you can completely cut power to the battery when you’re not using it. It’s an extra safety measure and also saves a lot of battery when you’re not using the motor, extending its lifespan.

The Benefits Of Using Three 36V LiFePO4 Batteries in Parallel

The 36V battery is “plug and play”. You don’t have to figure out how to connect three 12V batteries in series for higher voltages.

Even if one of the batteries is damaged, the whole system will not stop immediately, giving the user enough time to repair.

The Benefits Of Using Three 12V LiFePO4 Batteries in Series

When there is a 12V LiFePO4 battery failure, the entire system will not run, and the fault can be eliminated in time. and easy to replace. Also, unlike a 36V LiFePO4 Battery, your 12-volt battery doesn’t require a dedicated battery charger. They also feature engine start assist.

Using 12V LiFePO4 Batteries For 36V Batteries System

In the past, batteries were usually made of lead acid or AGM. However, we’ve made some incredible technological advancements, and recently, many application are now using lithium batteries. In fact, Li-Ion batteries are the standard recommendation for 36V Battery systems due to their longer life, lighter weight, safer components, and more stable power.

How Long Do 36V Golf Cart Batteries Last?

Obviously, when someone asks me about how long do golf cart battery last, we should distinguish between lead-acid batteries and lithium-ion batteries, because the lifespan of the two is very different, which is determined by the internal chemistry of the two. Below I talk about the lifespan of lithium and lead acid batteries separately.

The above diagram is the cycle life of Trojan Deep-Cycle Gel Batteries, the lifespan is 500times@80%DOD.That means if you charge/discharge your golf carts one time per day, your golf carts battery can last 500/365=1.36years. And if you charge/discharge your golf carts one time per two day, your golf carts battery can last 500/365*2=2.72years.

And if you charge/discharge your golf carts one time per two day, your golf carts battery can last 7000/365*2=32.86years.

In summary,
Golf carts Lead-acid battery can last 1-3years

Golf carts Lithium battery can last 10-20 years.
